> Unfortunately there isn't a standardized pack voltage and the range of what it can be is anywhere from 400 -> 900V. The CCS spec supports up to 1000 volts. All chargers support variable voltages. A car's pack voltage also changes continuously across the charge curve as the battery's state of charge increases. The pack is at its lowest voltage at 0% state of charge and at its highest at 100%. Here's an example of four cars charging, three at 400 volts and one at 800 volts. You can see how the voltage and amperage change across the charge curve: https://www.youtube.com/watch?v=T-Cil3seCHM |
