Cell balancing is a passive process that discharges those cells with the highest charge levels so that their charge levels more closely match the charge levels of other cells. It does not occur while charging is active, so it doesn't consume any charging power. Cell balancing occurs while the battery pack isn't being charged or discharged. It occurs more rapidly at higher charge levels.MKH wrote: ↑Wed May 15, 2019 3:58 amEarly in the charge cycle some of the time/energy will be used to either warm or cool the batteries to optimum charging temperature, late in the charge cycle some of the time/energy will be used in cell-balencing, which helps maintain the battery pack's 'health' and max charge it will take.
The level 2 EVSE really just tells the i3 how many amps it is allowed to pull from this station. That's it, all the decisions on how much power to push into the battery is made internally by the charging controllers on the i3 (EME). I suppose with one of the smart EVSE stations you could change the advertised amp limit to force the i3 to consume less power.CanisLupus wrote: ↑Thu May 16, 2019 9:28 amWhat would be interesting to know is 'For any given EVSE , which power level (kW) is it communicating to the vehicle as it's MAXIMUM Allowable ? ' . 30 Amps is close to our i3's maximum but if the EVSE doesn't allow our maximum then which power level will our i3 step down to ? The ChargePoint stations usually indicate about 5.8XX KW when I charge from them . Is 5.8XX one of the charge levels that our i3 will utilize ? With this thought in mind I might try the different settings in the charge level menu and see which power values show on a ChargePoint Station .
There aren't distinct power levels that an i3's charger supports. The charging power is the lesser of what an EVSE (AC) or charger (DC) can deliver and the maximum that an i3 can accept (~7.2 kW AC or 50 kW DC).CanisLupus wrote: ↑Thu May 16, 2019 9:28 amThe ChargePoint stations usually indicate about 5.8XX KW when I charge from them .
