IMREN 18650 Battery
Failure classification and cause analysis of lithium battery.
1、 Capacity decay failure
During the standard cycle life test, the discharge capacity shall not be less than 90% of the initial capacity when the number of cycles reaches 500. Or when the number of cycles reaches 1000, the discharge capacity shall not be less than 80% of the initial capacity. If the capacity drops sharply within the range of standard cycles, it belongs to capacity attenuation failure.
Safety of lithium battery vehicles powered by hydrogen fuel?
For a long time, due to the public's lack of sufficient understanding of hydrogen energy, they still have doubts about the safety of hydrogen fuel cell vehicles, forming an atmosphere of talking about hydrogen discoloration, which has become a major factor restricting the rapid development of the hydrogen fuel cell vehicle industry.
2) After 240s, the battery enters the stage of stable temperature rise, in which the battery temperature rises at the rate of 0.05 ℃ /min;
3) During the temperature stabilization phase, the battery temperature will continue to rise, but the battery temperature will not rise.
