Effect of temperature on the performance of electric vehicle batteries

Rechargeable battery, discharge occurs in the battery electrochemical reaction, the higher the temperature, the battery characteristics of the activity of each active increase, electrolyte viscosity reduction, overcast reduced, so that the electrochemical easy, electric mountain bicycles not vice versa easy to discharge when the lower temperature, the lower release capacity at extremely low temperatures, the release will be a significant decline in capacity, high temperature, and vice versa;
Charging the lower the temperature, the worse the charge acceptance, high charge voltage requirements, in order to be fully charged. Conversely the higher the temperature, the better the ability to accept charge, could easily lead to over-charge, thus requiring lower charge voltage, they are not caused by overcharging. This temperature change, a direct impact on the battery charge and discharge performance.
