Battery temperature control system, battery temperature control method, and non-transitory computer-readable recording medium

A battery temperature control method, comprising:

• acquiring a measured battery temperature of a battery module in a battery pack installed in an electric vehicle, the battery pack comprising the battery module, a temperature adjustment unit that adjusts the temperature of the battery module, and a battery control unit that outputs a set value for regenerative charging and a set value for output suppression to a vehicle control unit that controls an inverter connected between the battery module and a motor for driving;
• determining a target temperature of the battery module at the time of arrival at an installation place of a charger to which the electric vehicle is to head;
• and
• determining a combination of a set value for the regenerative charging, a set value for the output suppression, and a set value for the temperature adjustment unit such that the battery temperature becomes closer to the target temperature.

A non-transitory computer-readable recording medium having embodied thereon battery temperature control program causing a computer to implement:

• a module that acquires a measured battery temperature of a battery module in a battery pack installed in an electric vehicle, the battery pack comprising the battery module, a temperature adjustment unit that adjusts the temperature of the battery module, and a battery control unit that outputs a set value for regenerative charging and a set value for output suppression to a vehicle control unit that controls an inverter connected between the battery module and a motor for driving;
• a module that determines a target temperature of the battery module at the time of arrival at an installation place of a charger to which the electric vehicle is to head;
• and
• a module that determines a combination of a set value for the regenerative charging, a set value for the output suppression, and a set value for the temperature adjustment unit such that the battery temperature becomes closer to the target temperature.
