CHARGING DEVICE HAVING THERMOELECTRIC MODULE

Provided is a charging device having a thermoelectric device, including at least one battery unit. The at least one battery unit includes a battery and a thermoelectric module, wherein the battery is mounted on a first surface of the thermoelectric module and the battery contacts the first surface. When the thermoelectric module is provided with a supplying voltage through two voltage input terminals, a temperature difference is generated between a second surface of the thermoelectric module and the first surface, so that the thermoelectric module either heats up or cools down the battery depending on different battery temperatures and conditions, thus ensuring the charging efficiency and safety.
