英文摘要:
      Based on infrared thermal imaging technology and visual testing methods, the surface temperature variation characteristics and heat generation law of ternary soft-pack lithium battery under different working conditions were investigated. The ambient temperature, the discharge rate, and the ear clamping method are three variable conditions. The two are coupled to the control variable experiment to monitor the temperature rise of the battery surface. The results show that the optimal working temperature of the battery is 25 °C, to ensure that the different rate of discharge experiments at the most suitable working temperature, found that with the increase of the discharge rate, the heat generation increased, the surface temperature of the battery increased, the conductive clip clamping tab is compared with the copper clip holding tab This method will lead to insufficient overcurrent at the ear, a sharp increase in heat generation, and a significant temperature rise on the surface of the battery. This type of clamping is not conducive to heat dissipation of the battery, which provides a parameter basis for thermal battery design optimization and experimental operation. The test results have guiding significance for the optimization of the heat dissipation scheme.
