“Additionally, current batteries will suffer immensely in terms of loss of capacity.”

Seems like that much current into the battery would overheat it.

If the charging efficiency of an EV battery were 99%, meaning 1% of the charging wattage would go to heat, 10 KW would be heating the battery.

Wikipedia says the charging efficiency of a LI battery is 80-90 percent.

But this company must have something that works for some batteries.

Typical for home 120v systems and includes the losses in the charger.

Tesla Supercharging is greater than 90%.
