ACTIVE HEAT SHARING BETWEEN CABIN AND HIGH VOLTAGE BATTERY

Abstract: a vehicle includes a traction battery and an electric machine powered by the traction battery and configured to power wheels of the vehicle. the vehicle further includes a thermal-management system having a battery loop configured to circulate coolant through the traction battery, a cabin heating loop configured to circulate coolant through a heater and a heater core, a blower configured to circulate air through the heater core to heat a passenger cabin of the vehicle, and a valve configured to fluidly connect the battery loop and the heating loop when the valve is in a first position and configured to fluidly isolate the battery loop from the heating loop when the valve is in a second position. a controller is programmed to, responsive to (i) the battery charging, (ii) a temperature of the battery being less than a first threshold, and (iii) a temperature of the heater core being greater than a second threshold, energize the heater and command the valve to toggle between the first and second positions in succession such that heat generated by the heater is circulated to the battery and the heater core.
