The Kona has LG Batteries, the Niro has SK. From other blogs, the Ionic 5 P45 has problems with its battery management system. When cold below 20 deg C it charges at half maximum i.e. 110Kw. When battery is hot after charging at maximum, the power to the motors is limited to 60Kw from the normal 250Kw until they cool down. The EV6 prototype also has problems when rapid charging, briefly dropping to 8 or 10 Kw until temperature drops. Does anyone have any information on what batteries are in the EV6 and any temperature issues?
