1. A battery temperature control system that maintains a temperature of a battery mounted on an electric vehicle within a target temperature range while the electric vehicle is stopped, the battery temperature control system comprising:
a processor configured to:
estimate an environment in which the electric vehicle is stopped;
set a reference temperature from a plurality of pieces of temperature information based on the environment estimated by the processor;
predict a temperature transition of the battery based on the reference temperature; and
adjust the temperature of the battery based on the temperature transition of the battery, wherein:
the plurality of pieces of temperature information comprises first temperature information, based on a weather forecast, and second temperature information, based on an outside air temperature sensor mounted on the electric vehicle;
when the environment in which the electric vehicle is stopped is outside a building, the reference temperature is the first temperature information;
when the environment in which the electric vehicle is stopped is inside a building and a position of the electric vehicle is a previously registered location, the reference temperature is the first temperature information; and
when the environment in which the electric vehicle is stopped is inside a building and a position of the electric vehicle is not a previously registered location, the reference temperature is the second temperature information.
