Claims20
A battery system for an electric vehicle, comprising:
- a first battery module including a first heater positioned within the first battery module, wherein the first heater is configured to be powered solely by the first battery module;
- a second battery module including a second heater positioned within the second battery module, wherein the second heater is configured to be powered solely by the second battery module;
- and
- a control system configured to:
- receive a triggering signal, wherein the triggering signal is indicative of a defect in the second battery module;
- and
- in response to the triggering signal, activate the first heater without activating the second heater to dissipate energy from the first battery module.
