TRACTION BATTERY HEATER CONTROL

摘要

Vehicle high-voltage side heater systems and methods are described. In an example, a controller to input a modulated control signal from a low-voltage side is connected to a high-voltage side heater, which is controlled by the modulated control signal from the controller. The controller can be on low-voltage side and not directly connected to a low-voltage side power but does derive the control signal from an input signal, which can be pulse width modulated.

主权项

1. A vehicle high-voltage side heater system, comprising:
a controller to input a modulated control signal from a low-voltage side; and a high-voltage side heater electrically coupled to and galvanically isolated from the controller, the high-voltage side heater being controlled by the modulated control signal from the controller to connect a high voltage to the high-voltage side heater.
