Abstract:
1. A battery temperature control method for controlling a temperature of a battery, comprising: detecting the temperature of the battery; detecting a temperature of a temperature regulating medium to be sent to the battery in order to regulate the temperature of the battery; and controlling a flow rate of the temperature regulating medium based on the temperature of the battery, the temperature of the temperature regulating medium a target temperature and the specific heat of the battery such that the temperature of the battery becomes close to the target temperature, wherein controlling the flow rate includes: determining a thermal capacity necessary for setting the temperature of the battery to the target temperature, by multiplying the specific heat of the battery by a value that is generated by subtracting the target temperature from the temperature of the battery; determining a temperature regulating ability of the temperature regulating medium at a standard flow rate, by subtracting the temperature of the temperature regulating medium from the temperature of the battery; dividing the thermal capacity by the temperature regulating ability in order to determine a ratio of the flow rate of the temperature regulating medium to the standard flow rate, determining the flow rate of the temperature regulating medium by multiplying the standard flow rate by the ratio, and managing the flow rate of the temperature regulating medium such that the flow rate of the temperature regulating medium that is determined is sent to the battery.
