Abstract
An electrical storage device heater system according to an exemplary aspect of the present disclosure includes, among other things, an electrical storage device, a heater configured to regulate a temperature of the electrical storage device and a controller configured to actuate the heater using power sourced from a location separate from the electrical storage device.
Claims16
A vehicle, comprising:
- a first power source located on-board said vehicle;
- a battery system powered by said first power source, wherein said battery system includes a high voltage electrical storage device, a heater that selectively heats said high voltage electrical storage device, and a switch that selectively couples said heater to said first power source;
- and
- a controller that controls the operation of said heater by actuating said switch to couple said heater to said first power source, wherein said controller is powered by an alternative power source that is separate from said first power source.
1 more element
A method, comprising:
- checking whether a vehicle is in a key ON or key OFF condition with a controller;
- connecting a heater to a high voltage electrical storage device of a battery system of the vehicle if a temperature is below a temperature threshold and the vehicle is in the key OFF condition;
- and
- disconnecting the heater from the high voltage electrical storage device if the temperature is above the temperature threshold or the battery system is disconnected from an external power source.
1 more element
A battery heater system for an electrified vehicle, comprising:
- a high voltage battery system that includes a plurality of battery cells, a heater that selectively heats said plurality of battery cells, and a switch that selectively controls power flow to said heater;
- a power supply separate from said high voltage battery system that selectively powers said heater when said switch is closed;
- and
- a controller configured to control operation of said switch to supply power to said heater based on at least battery cell temperatures, a key ON/OFF condition, and a converter AC/DC active signal.
