What is the EDrive system for the Toyota Prius and how does it work?
The EDrive system replaces the existing Prius NiMH battery and Toyota battery control computer with a larger advanced lithium-ion battery and a proprietary battery monitoring and control system. The new system allows the Prius to be charged at home using a standard 110/120V home outlet. With the larger battery, the Prius runs in electric only ‘EV’ mode at lower speeds or when less power is needed. The result is EV driving and electrically boosted gasoline driving for the first 40 or so miles with a gasoline efficiency of over 100mpg. After the 40 mile ‘boosted’ range, the vehicle performs just like a standard Prius until it is plugged in again. The battery system is about 2″ higher and 3″ longer than the Toyota NiMH battery. It is installed under the rear cargo carpet without limiting access to the spare tire. A small display is mounted on the dashboard.
