Abstract: A temperature control apparatus and a temperature control system include at least one liquid storage device for storing liquid, at least two liquid supply devices, and a controller. Each liquid supply device is connected to the at least one liquid storage device through a first multiport valve to obtain liquid and is connected to a temperature regulating device through a second multiport valve. The controller is configured to control the first multiport valve and the second multiport valve that are connected to the controller to be conducted or not to be conducted. When the first multiport valve and the second multiport valve are conducted, each liquid supply device outputs the obtained liquid to the temperature regulating device. The temperature regulating device regulates a temperature of the liquid injected by each liquid storage device, and then supplies the liquid to at least one battery system.
