| Abstract: | Battery temperature is an important factor affecting the performance of the battery pack.High temperature will seriously affect the capacity and life of the battery,and cause irreversible damage to the structure of the battery,and even lead to safety accidents,so cooling the battery pack is necessary.The thermal characteristics of lithium-ion batteries,the influence of temperature on power batteries and the importance of heat dissipation to power batteries were described.The common ways of heat dissipation of power battery were introduced,and the research status of air cooling heat dissipation was mainly introduced.Forced cooling and active cooling were compared,the serial ventilation and parallel ventilation in forced cooling were analyzed.The results show that parallel ventilation is superior to serial ventilation. |
