The function of battery extrusion needle punching integrated machine The battery squeezing and needle punching integrated machine is suitable for simulating the situation where various types of batteries are subjected to squeezing and puncture during use, transportation, storage, or disposal of household waste. The extrusion direction of the extrusion test should follow the following rules: […]

Explanation of Battery Charging Test Principle The basic principle of charging and discharging lithium batteries is achieved through the insertion and extraction of lithium ions between the positive and negative electrodes. During the charging process, electrons on the positive electrode run to the negative electrode through an external circuit, while lithium ions pass through the

The environmental test chamber simulates the destructive effects of natural environmental climate on modern industrial products through technological means. Representative tests of the environmental test chamber include low pressure (high-altitude) test, high temperature test, low temperature test, thermal shock test, solar radiation (sunshine) test, rain test, moisture resistance test, mold resistance test, salt spray test,
