Я все-таки решил поискать - интересно же разобраться, как обычно.alpax писал(а):На форумах писали, что замеряли именно сколько было вытянуто из сети, и сравнивали с тем, сколько набралось в батарее. В общем, все не так плохо.
Нашел: потери все же заметные, но приемлемые. Народ пишет о 80-85% эффективности. Вот, например, ветка: https://forums.tesla.com/en_CA/forum/fo ... ficiency-0

I have a TED5000 monitoring my garage breaker panel, which is 99.9% used to charge the LEAF. I see around 82% efficiency, if the car's measurements are accurate.

After four years with my Roadster my results are as follows: of the energy taken from the grid, 78% is used to propel the car (245 kW/Mile), 5% is used up by the car while it is sitting idle (17 kW/Mile), 16% is lost inside the car during charging (54 kW/Mile) and 1% is lost getting from the grid to the car (3 kW/Mile). So the charging efficiency of my Roadster is 271 kW / 328 kW = 83%.

I charged yesterday at a ChargePoint location. The total drawn was 6.250 Kw and energy into the car showed 5.081 from their information. That gives an efficiency of 81%.

It's still early to account for all the variables like battery heaters coming on, vampire load, etc, but so far I am seeing about 86% efficiency (ie, 86% of the energy that comes from the wall makes it into the battery) charging at 40A/240VAC.
