How many kWh does it take to charge a 100kWh vehicle battery?
There's a few factors involved:
Resistive losses, transformer losses, switching losses.
Lithium ion batteries charge at 4.2V but discharge at 3.7V, but that's not true for the entire charge-discharge cycle.
Does anyone have an approximate figure for the charge efficiency?
On pay-chargers, which side of the charger circuitry is the meter? On the mains side or on the output side?
