Carbon Electrode Cell Offers Speedy Charge, Will Soon Power Urban Cars.

“In this case, it is set to be 100 kWh, and it was said that it would operate at 400V, so the current value at that time would be 250A. If you charge at 250A, you can do it in 1 hour, but if you charge at 20C, it will be fully charged in 3 minutes, so you will have to flow a large capacity of 5,000A. In that case, it is calculated that even 100 kWh can be fully charged in 3 minutes by charging with 5,000A.

In fact, in order to achieve a high rate with a large capacity battery pack, a detailed calculation is required because of BMS and module design, management system between modules, load on the battery cell alone, allowable deterioration value, etc.”
