Abstract

The invention provides a constant temperature device required in a battery charge-discharge testing process, and belongs to the technical field of batteries. The constant temperature device comprises a tank body, a temperature controller, a thermoelectric semiconductor refrigeration assembly, a cooling fan, a thermocouple, a dehumidifier, a battery clamp and a power supply power source. The tank body has the heat preservation effect. A front cover plate capable of being opened is arranged on the front side of the tank body, the thermocouple, the cooling fan, the thermoelectric semiconductor refrigeration assembly, the dehumidifier and the battery clamp are arranged in the tank body, the temperature controller is arranged at the top of the outer side of the tank body, and the temperature controller is simultaneously connected with the thermocouple, the thermoelectric semiconductor refrigeration assembly and the cooling fan through holes in the tank body to achieve control over temperature rise and temperature drop. The constant temperature device has the advantages of being easy to operate, practical, convenient to maintain and low in cost, and the constant temperature device is suitable for battery charge-discharge testing.

Description

technical field [0001] The application of the present invention relates to a constant temperature device, in particular to a constant temperature device for battery charging and discharging tests, which belongs to the technical field of batteries. Background technique [0002] The current testing of the charge and discharge performance of rechargeable batteries and positive and negative materials is mainly assembled into button batteries or cylindrical batteries, which are tested by a charge and discharge tester. The charge and discharge performance of batteries is greatly affected by temperature, especially for lithium-ion batteries. In order to accurately test the performance of batteries and positive and negative electrode materials, it is necessary to perform charge and discharge tests on batteries under different temperature conditions. Especially when the temperature difference between day and night is large, it is difficult to accurately determine the measurement resu...
