Reduced Power Mode In Electric Cars (Turtle Mode)

It can appear when the battery is nearly empty. Very high or very low battery temperatures can also trigger it, for example after repeated fast charging or in deep frost. Some faults in the motor or inverter cause it as well. Some electric cars also limit power in very cold weather until the battery has warmed up.

The battery management system lowers the permitted current, which reduces acceleration and top speed until conditions improve.

Charge as soon as possible if the battery is low, and avoid motorways where low speed is dangerous. If it appears with a well-charged battery at normal temperatures, have the car diagnosed.
