Abstract

The invention discloses a semiconductor temperature control battery box. The battery box comprises a circuit for controlling a semiconductor refrigeration chip and a box body satisfying structural requirements of the battery box; and a part of the box body is manufactured of the semiconductor refrigeration chip. The battery box has the following functional features: a. a simple structure substitutes separate heating and cooling system of prior art; b. the battery box comprises no moving part and generates no noise; c. the battery box has a high heating efficiency, and a heat pump technology realizes heating heat quantity to the box body greater than the energy consumption; d. the battery box has good sealing effect, does not need air exchange, and can be made into a fully sealed box body to realize the most stringent grade of dustproof and waterproof; and e. heating and cooling are actively controlled to realize constant temperature control on the battery box.

Description

technical field [0001] The invention relates to a battery case capable of flexibly controlling the internal temperature. Background technique [0002] In modern society, with the development of new battery technology, secondary batteries are used to store and provide energy in more and more fields. Especially in the energy storage of mobile devices, there are more and more applications, especially the demand for batteries in new energy vehicles is increasing. However, current secondary battery products are extremely sensitive to ambient temperature because the technical principle is electrochemical reaction. When the temperature is too low, its chemical activity decreases, resulting in a significant decrease in the effective capacity of the battery or even failure to charge and discharge. In severe cases, it will also cause irreversible changes in the battery electrolyte and positive and negative electrode structures, seriously affecting battery life. When the temperature ...
