Abstract: A charging control system includes: a battery rechargeable with electric power from an external power supply; a battery cooler that cools the battery; and a controller that controls charging of the battery and cooling of the battery. The controller includes processing circuitry configured to: acquire, in a case where charging is included in a scheduled travel plan, noise information related to a charging system that performs the charging and environment information of a charging place where the charging is performed; determine a quietness requirement of the charging place based on the noise information and the environment information; determine a target temperature of the battery at the time of arrival at the charging place or at the time of start of the charging based on the quietness requirement; and control the battery cooler based on the target temperature of the battery.

Abstract: A battery temperature adjustment system includes: a battery; a battery temperature adjustment device; and a control device configured to control the battery and the battery temperature adjustment device.

Abstract: A battery temperature control system, maintaining a temperature of a battery mounted on an electric vehicle within a target temperature range while the electric vehicle is stopped, includes: an environment estimation unit configured to estimate an environment in which the electric vehicle is stopped; a reference temperature setting unit configured to set a reference temperature from a plurality of pieces of temperature information based on the environment estimated by the environment estimation unit; a battery temperature transition prediction unit configured to predict a temperature transition of the battery based on the reference temperature; and a battery temperature adjustment unit configured to adjust the temperature of the battery based on the temperature transition of the battery.
