Battery Module, Battery Device, and Battery System Having Thermal Management Design

The present invention provides a battery module, a battery device, and a battery system having a thermal management design. It utilizes a three-stage thermal management design of the battery module, the battery device, and the battery system to not only prevent the battery cells from being impacted by the environmental temperature, but also efficiently control the temperature of the battery cells, such that the battery cells can reach the requirements of temperature equalization and appropriate operating temperature. The thermal management design of the battery module is mainly a design of a battery cell charging and discharging circuit having heat exchange. The thermal management design of the battery device is mainly a battery device enclosure having a thermal insulation ability, so as to avoid or reduce the impact of the environmental temperature to the temperature of the battery module. The thermal management design of the battery system mainly comprises a temperature control medium circulation system which can enable the conditioned temperature control medium to exchange heat with the battery module by means of the battery device.
