2023 NHL Entry Draft favorites: Matvey Michkov will fight for the top three, two more Russians can be selected in the first round – July 11, 2022

Daria Tuboltseva

ca.

Draft is traditionally a high-profile event in North American hockey. For two days on July 7 and 8 in Montreal, NHL clubs chose the best young players. This year, the hosts had the first pick, Montreal sensationally settled on the candidacy of the Slovak Juraj Slafkovski, and the favorite Shane Wright went only fourth to Seattle. Another player from Slovakia, Szymon Nemec (New Jersey), came second, and Logan Cooley (Arizona) was third. For several days, experts and journalists have already managed to discuss the choice of teams this time and began to argue who will be on top in a year.

The 2023 draft rankings haven’t come out yet, but various publications have already compiled the top 10 and top 30 best prospects coming out the next year at Rookie Fair. Russians and Europeans were not included in the list of the best. The favorite is (and not the first year) Connor Bedard . The 16-year-old Canadian (turning 17 on July 17) is described as as talented as McDavid and predicted to be a stellar career in the NHL. At the age of 15, he received an exclusive status to play in the WHL (Western Hockey League). Such a status is very rare, as a rule, only players who later became stars (Tavares, Ekblad, McDavid) were awarded this.

Connor spent half of last season on loan in Sweden, but this year he played a full season in the WHL. He became the youngest player in league history to score 50 goals in a season. Bedarn has 100 (51 assists 49) points in 62 games for the Regina Pets and is the league’s fourth scorer and second scorer. The striker has already gone to the Junior World Championship twice, where he dominated his peers. He lit up at the MFM, but they didn’t finish it, so the hockey player (unlike Michkov) will have a chance in August. Experts note the frenzied performance of the young player.

“What really impresses me is how he gets things done no matter what. Even if you think that an opponent is in his way, he somehow shoots and the puck ends up in the net. He has a unique shot and a unique ability to choose the right position for the shot “,” says Joey Tenute of the NHL Central Scouting Bureau.

Scouts compare Bedard to a legend like Marcel Dionne and see him as the favorite in the fight for the first seed in the draft. His compatriot will fight him Adam Fantilli of the USHL. The 17-year-old Canadian will play next season in the NSAA for the University of Michigan, which means he will get the practice of playing hockey players much older than him. The top three is closed by Matvey Michkov . The Russian, despite the removal of the national team from international tournaments and a four-year contract with SKA, is still highly rated.

“Michkov is a winger with all the skills needed to become a star. His acceleration is excellent, he is an energetic player who seems to be a split second ahead of the game. He is a top-notch passer, able to create chances on almost every shift. Michkov is currently the number one prospect in Europe for the 2023 draft, , said NHL European Scouting Director Goran Stubb.

17-year-old Michkov made his KHL debut last season, scoring 5 (2+3) points in 13 games for SKA. In the MHL, Matvey looked great, gaining more points per game in the regular season. In the upcoming season, the striker should get more game practice in the KHL, as he obviously outgrew the level of youth hockey. However, even if Michkov spends an enchanting season, he has no chance of becoming number one in the draft – the contract with the St. Petersburg army team is to blame. It is valid until 2026 (however, a player can apply for termination 16 months in advance). NHL clubs don’t want to spend such a high pick on a hockey player who can’t immediately come to the team’s location. Somewhere near this trio Dolibor Dvorski , who is preparing to continue the successful march of the Slovaks in the draft. The 17-year-old center plays in Sweden, has already traveled to the MFM and fought with his team at the JWCH in the second group. A few more Russians have a chance to leave in the first round in a year. These are defender Mikhail Gulyaev (Omsk Hawks) and forward Daniil But (Loko). In the second round, and possibly in the first, they see defenders Ivan Remezovsky (SKA-Varyags), Dmitry Simachev (Loko) and goalkeeper Yegor Zavragin (Mammoths of Yugra).

The last Russian to make it into the top three in the draft was Andrey Svechnikov in 2018. And, as time has shown, he performs in the NHL even more successfully than Rasmus Dalin, who was chosen first, although this is probably the case in the teams. According to his potential and talent, Michkov can become a player of the level of Svechnikov or even higher. But Matvey chose to develop in Russia, and this will definitely affect his prospects for the draft.

Maha Energy Powerex MH-C9000 Charger (NiCd and NiMH AA/AAA batteries) – “Great analyzer charger.”

Maha MH-C9000 is a charger-analyzer (charger) with wide functionality, convenient operation, high quality and reliability. Deservedly has the title of the best in its class for working with nickel. It has been produced for many years, while remaining a leader in terms of basic characteristics and operation algorithms.

ZU is manufactured by the American company Maha Energy. Assembly – Taiwan, own production. The company has been operating since 93 and is currently a global manufacturer of batteries and chargers. The emphasis is on guarantees of high quality and reliability: mandatory testing of all device functions and automated quality control of each ac-ra without human intervention. The main brand of the company is Powerex. Under it, the highest quality products are produced, and a large volume goes under OEM.

Bought in la-crosse. On my copy there was a small problem with one of the control buttons: it stuck slightly. I had to take it apart and make some holes. At the same time, I looked at the board and the circuit: well done, the elements are placed freely, each channel has its own temperature sensor.

Main features:

Four slots for 1-4 AA, AAA batteries (NiMH, NiCD).
Supported capacity: 100-20000 mAh.
Charging current: 200-2000 mA, step 100 mA, default 1000 mA (auto-on 10 sec after installation of the acc-ra and no operation).
Discharge current: 100-1000mA, step 100mA, default 500mA.
During operation, the display alternates between capacitance, current, voltage, time and cycle.
Modes: charge (CHARGE), update / analysis (REFRESH / ANALYZE), forming (BREAK-IN), discharge (DISCHG), cycle (CYCLE).
Charging current (drip charge): 10 mA.

The main differences from analogues can be noted: the ability to set high currents for fast charging and discharging on each channel: up to 2 and 1 A, respectively – obviously calculated with a margin, four completely independent slots, a clear large and informative display with bright backlight (not turns off). With an unsatisfactory check of the resistance of the batteries before charging, it gives a HIGH error.

A few words about algorithms for determining the charge, why and when it is important. They write that they have excellent developments in schematic, software solutions and one of the best algorithms in terms of sensitivity and correctness. This was one of the highlights of my choice, plus a wide current range and a fixed 100mA step. The manufacturer’s website says:

The MH-C9000 uses a combination of Negative Delta V, Zero Delta V, Peak Voltage, time and temperature to determine the end-of-charge. In addition, proprietary algorithms are used.

It sounds nice, almost all the characteristics of the transient process are listed, by which you can fix the end of the charge: voltage drop (-dV), plateau (dV=0), voltage peak. Temperature and time are also tracked in the algorithm, plus used in the event of a failure or malfunction. As for proprietary algorithms (proprietary algorithm), you can find on the net that we are talking about the inflexion algorithm (by derivative) .

In general, by and large, when charging with low currents, the intelligence of the charger is not needed, the timer function is enough. The issue of algorithms is relevant at relatively high currents. Charging with high currents in itself leads to faster degradation of the batteries and causes increased heating, which is even worse, especially at the end of the process. Therefore, it is important to slow down the process in time. Most devices use the -dV algorithm, but it almost always causes some overheating of the ac-ra. Switching off on a plateau with a time delay gives an even greater “recharge” and heating of the ac-ra. The temperature protection on the charger is set to emergency values ​​and is not used to control the charging process. In MH-C9000 temperature is included in the algorithm, so each channel has its own sensor and the size is made to exclude mutual influence. Thus the inflexion method (on the derivative of voltage and temperature) works best, i.e. the device starts to slow down the process when registering the maximum growth rate of the voltage value, taking into account similar temperature data. At the same time, the ac-r is slightly undercharged. After that, the device enters the final charge mode: 100 mA, 2 hours. And then a drip charge of 10 mA.
This information and some other interesting points are provided on the forum by the developers.

I’ll leave a quote for myself, maybe someone else will be interested.

1) Inconsistent discharge voltage between MH-C9000 and the BC-900
The MH-C9000 and BC-900 use different methods for measuring voltage during discharge. The MH-C9000 measures the voltage under a 1000mA load, while the BC-900 measures the open circuit voltage between the discharge pulses. We chose this particular design because the open circuit voltage does not fully reflect the condition of the battery and that the under-load voltage is the figure-of-merit for real devices. For instance, a highly resistive battery might show a high open circuit voltage (measured between discharge pulses). However, as soon as the discharge current is drawn, the voltage will drop significantly. Here is an example, for a battery with 0.1 ohm DC resistance, a open circuit voltage of 1.2V will give a under-load (1A) voltage of 1.1V.
We’ve come across a lot of AAA batteries (well-known and off brand, new and old) that have DC resistances exceeding 0.3 ohm. Their open circuit voltage, measured between discharge pulses, actually never reach the cutoff and the discharge continues until the MOSFET is unable to draw current (due to insufficient differential voltage). The under-load voltage will already be 0.8V but the open circuit voltage will still be above the discharge cutoff. As a result, the discharge never ends!
However, under-load voltage has one drawback – it also reflects the contact resistance between the charger and the battery. In a 2-point measurement (as used in the Mh-C9000 where only two points are used to measure the voltage across the battery, one on the positive terminal and one on the negative terminal), the voltage drop includes those across the contacts as well. Since no contact is perfect, it is possible to develop a small voltage drop between the battery and the charger. Commercial battery testers overcome this problem by using the so-called “4 point measurement” while two probes carry the current and two probes measure the voltage (so that the contact resistance is not measured).
2) Non-monotonic discharge voltage (with respect to time)
It is normal to have a non-monotinic discharge voltage (and charge voltage as well) due to a change in the battery resistance. This usually happens with batteries that have been sitting on the shelf for a while, and old batteries.
3) Pre-mature discharge termination
It rarely happens, but it does. Did you encounter the problem frequently? on both units? Pre-mature discharge termination is most likely due to a sudden drop in the measured voltage (such that the charger sees a voltage less than 0.9V), often due to a jiggle to the battery, noise, etc.
4) Why isn’t the battery fully charged when DONE shows? Why the 2hour top off charge?
It is a balancing act between undercharging and overcharging batteries. Maha design chargers differently depending on the target market. In the case of the MH-C9000, we favor undercharging in order to extend battery life. Typically, batteries are 93-95% charged when DONE pops up. This is when the user-set charging current stops and the 100mA top-off current kicks in. Our research has shown that this termination strategy will substantially increase the life of the battery by preventing overheating. I think most folks here will agree that the MH-C9000 is a “cool” charger.
5) Pre-mature charge termination
Charge termination issues do happen, but rarely. The MH-C9000 measures the battery voltage (both the absolute and relative value, and as a function of time), temperature (absolute and relative, and as a function of time) and puts the information into a matrix to evaluate whether to terminate the charge or not. At the design level, we decided that we prefer not to overcharge the battery. Occasionally, especially with new batteries or those sitting around for a while, premature charge termination would occur. However, missed termination is extremely rare because of our design choice.
6) Capacity difference between the MH-C9000 and BC-900 the BC-900, when our laboratory-grade instrument consistently gives about 2550mAh). This has to do with two things: 1) accuracy of the discharge current measurement, and 2) accuracy of the time base. The MH-C9000 has a 1% tolerance in the discharge current measurement. Furthermore, the MH-C9000 uses a quartz oscilattor time base (you can see them if you open the charger, I think there are some photos here on CPF) whereas the BC-900 uses a resistor-capacitor (RC) network as a time base which is less accurate .
I trust the BREAK-IN capacity on the MH-C9000. It is typically within 2% of the capacity measured on a calibrated battery analyzer.
I hope this answers some of the questions raised.

The main point of the algorithms in this memory is the preference for a small undercharge of the batteries. The instructions recommend a minimum charge current value of 0. 3C (capacitance) for correct operation, at low values ​​the transients are poorly expressed. But in general, on good batteries, soft charge with currents less than 0.3C works fine (I set 400 mA for 2k capacity). On some “old” ak-ah, it holds for a long time. It is necessary to calculate and control the charge time so as not to heat just like that. I rarely expose large currents for fast charging if necessary.

A little more about testing batteries for resistance. The first few seconds after starting a charge, the MH-C9000 always performs a “high resistance” test to identify batteries that are not safe to charge, including batteries. Charging such batteries can damage the charger, overheat or explode. For this, high voltage is applied. Batteries that show a HIGH error will not be charged by the charger. From experience, the ak-ry rejected by him are practically no good. In other devices, they can take a small charge and work for a while. Such ak-ry need to be disposed of. And if you charge, then with a minimum current and consider the charge time according to the real capacity, because. they heat up more and often begin to leak, especially at high currents.

It must be said that the default settings (when installing batteries) are not optimal for long-term operation. Not critical, but you need to press the buttons: anyway, first you always put it on discharge, then charge – 400, in principle 500, 600 mA can also be put on large capacities.

And so on modes plus comments based on experience:

1. CHARGE (charge): you can select a current of 200-2000 mA (mA), step 100 mA. As I already wrote, after the end of the charge (appearance of the inscription DONE), there is a final charge (100 mA, 2 h) and while the device is turned on, the ak-r will remain on recharging with a low current – 10 mA to compensate for self-discharge. Charging works in all modes after charging (excl. DISCHG). The current must be set for each slot. Inconvenient: in most cases, you have to work with the same type of ak-mi and it would be possible to implement duplication of settings for the first slot. When the charger is turned on and the acc-ra is installed, time is given to select the mode, if there are no actions, after 10 seconds the CHARGE mode is activated with a charge current of 1000 mA. In my opinion, the default value of the charge current exceeds the optimal performance even for batteries with a conditional capacity of 3k. It fits into the general recommendation of 0.3C. But this figure is determined to reduce the charge time as much as possible while maintaining a “satisfactory” service life. From experience, it is better to set the charge currents to about 500 mA for 3k capacities, the determination of the full charge works correctly. Charging with a current of 1000 mA still gives a noticeable reduction in the life of the batteries. Still very quickly begin to degrade “weak” ac-ry from the set. It should also be taken into account that the charge comes in pulses with a periodic short pause. In reality, I did not look at the process on the oscilloscope, what are the pulse values ​​​​and how it correlates with the current value on the screen.
2. REFRESH/ANALYZE (refresh/analyze): the mode is convenient for determining the actual capacity. Can be used as a single workout. Charge (the current is set, if there are no actions, the mode will work with default values: charge with a current of 1000 mA, discharge – 500 mA), then pause for 2 hours with recharging with a current of 100 mA, the battery gains maximum capacity. Then discharge and again pause for 1 hour. During this time, the chemical processes in the ac-re come into equilibrium. The resulting discharge capacity will be displayed at the end of the mode. And the final charge.
3. BREAK-IN (shaping): essentially the same as the second mode, but with low current over time – capacitance analysis according to the IEC standard. Recommend for new ak-s. I don’t use this mode. The process is long and experience makes no sense.
   Charge current 0.1C 16 hours, pause 1 hour, discharge current 0.2C, pause and charge.
4. DISCHG (discharge): a very useful mode for preventing loss of capacity, it ends at a voltage of 0. 9 V. I usually set 200, 300 mA to completely discharge all batteries in the kit before charging.
5. CYCLE (cycle): up to 12 charge-discharge cycles can be set, the mode ends with a charge. They recommend it for restoration, I don’t use it: a very long process at low currents, it makes no sense to mess around with rubbish. Ac-ry is regularly in my business, the capacity goes away irrevocably in accordance with the term of work. On the recumbents, there is no particular increase after this regime either. Maybe there is a sense in NiCD.

As a result, the MH-C9000 helps to comply with the recommendations for operation, conditions, operating modes of the batteries and maximize their service life. With proper use, ACs really live for a long time, the difference is several times from budget options at medium and high currents. Talk about restoration is greatly exaggerated and the process takes a long time – up to a week or more, at current prices for ak-ry – this is generally unjustified, except that NICD is in a short period of improper operation.
