The present invention relates to a system for maintaining battery cycle life for battery-powered electric vehicles. Current battery-powered electric vehicles such as automobiles and trucks suffer from short cycle lifes of their batteries, meaning that these vehicles' batteries will become unusable well before the normal useful life of combustion engine powered vehicles. Owners of vehicles using my system will enjoy vehicles with acceptable ranges, acquisition and operating costs, yet will enjoy battery lifes as long or as longer than the useful life of combustion engine vehicles.

The disclosure provides a control device for a hybrid vehicle, which can prevent overcharging the battery and effectively utilize the power generated by an electric motor operating as a generator to avoid useless wasted power. The hybrid vehicle includes an engine, an electric motor, a battery, an engine rotational speed sensor, a battery temperature sensor, and a fuel cutting part that stops the operation of the engine according to a specified operating condition. In the state where the operation of the engine is stopped by the fuel cutting part, the control device operates the electric motor as a generator when the rotational speed of the engine is equal to or below a specified value and the battery is chargeable in terms of temperature, and drives a heater with the power generated by the electric motor operating as a generator when the battery is unchargeable in terms of remaining capacity.

This patent application is directed to thermal management systems of vehicles with an electric powertrain. More specifically, the battery system and one or more powertrain components and/or cabin climate control components of a vehicle share the same thermal circuit as the battery module through which heat can be exchanged between the battery module and one or more powertrain or climate control components as needed.
