Abstract

The invention discloses a thermoelectric parameter testing device of a battery. The thermoelectric parameter testing device comprises a battery charge and discharge setting module (1), a heat-conduction calorimetric measurement module (2) and a signal processing module (3); a to-be-tested battery fixing and wiring device (21) is put into a calorimetric bottle (22) and then put into a calorimetric tube (23); the battery charge and discharge module (1) provides different electrical parameters of the battery to be tested through the battery fixing and wiring device (21), so that the battery to be tested goes through different processes such as charge and discharge, and change curves of current, voltage and heat flow along with the time in the process are measured at the same time, and characteristic parameters representing discharge and discharge performances and security performance of the battery are obtained through an analyzer (31). The thermoelectric parameter testing device is high in intelligent degree and simple in testing method; the security performance of the battery can be evaluated when the electrical performance of the battery is evaluated by measuring heat and electric parameters and a built intelligent model, and various batteries can be effectively detected under the condition that artificial interference does not exist.

Description

technical field [0001] The invention relates to a battery thermoelectric parameter testing device, especially a measuring device for simultaneously measuring voltage, current and heat flow during charging and discharging of a battery. Background technique [0002] During the battery production process, the detection of battery status parameters is the key to ensure the quality of the battery. Lithium batteries are lighter, have no memory effect, and have a slower self-discharge rate than NiMH or NiCd batteries, and are widely used as rechargeable batteries for modern electronic devices such as smartphones and laptops, as well as for electric vehicles, power tools In high-power applications such as energy storage and energy storage, lithium-ion batteries also have outstanding safety issues. [0003] With the rapid growth of the battery industry, the testing equipment used in the manufacturing process has also become very important. The typical functions of current battery t...
