High and low temperature alternating humidity and heat test chamber for high and low temperature discharge test of electric bicycle lithium battery
High and low temperature alternating humidity and heat test chamber. With the development of new energy in our country, electric bicycles have also ushered in a new stage of development. However, the high and low temperature use environment of lithium batteries for electric bicycles is also worrying. Therefore, high and low temperature discharge tests are necessary. The following is a small editor of the huanyi instrument, to take you to understand the high and low temperature discharge requirements of lithium batteries for electric bicycles.
1. Test equipment: high and low temperature alternating humidity and heat test chamber (also called constant temperature and humidity test chamber)
2. Model selection: Huanyi HYH-225
3. Low temperature discharge:
In an environment with a temperature of 23°C±2°C, after the battery pack is charged according to the prescribed method, put it in a low temperature chamber with a temperature of -20°C±2°C for 16 hours at a constant temperature. Then, in this temperature environment, it was discharged to the termination voltage with a constant current of 2I(A), the discharge time was recorded, and the discharge capacity was calculated.
4. High temperature discharge:
In an environment with a temperature of 23°C±2°C, after the battery pack is charged according to the prescribed method, put it into a high temperature chamber with a temperature of 55°C±2°C for 5 hours at a constant temperature. Then, in this temperature environment, it was discharged to the termination voltage with a constant current of 2I(A), the discharge time was recorded, and the discharge capacity was calculated.
The above are the requirements for the high and low temperature discharge test of the electric bicycle lithium battery in the high and low temperature alternating humidity and heat test chamber.
