The battery temperature has a huge influence on the activity of the internal activated enzyme, which in turn affects the battery electrochemical reaction rate and affects the lithium-ion deintercalation rate and diffusion migration rate in the battery. The battery temperature keeps accumulating in the middle and later stages of charging. If the battery temperature is too high, part of the energy will be converted into heat consumption, resulting in insufficient charging capacity. And in severe cases, it will lead to thermal runaway and burning of the battery. If the temperature is too low, the reaction of the lithium-ion battery is slow, the charging rate reducing, and the charging time is prolonged. The battery temperature-acceptable charging current curve shows that charge at 25℃ is best for the battery performance. Greenbatt battery support fast-charging.
Ambient temperature affects the electrolyte concentration and activity of the battery. When the temperature is higher, the activity and concentration of the electrolyte are higher, and the diffusion and migration rates of lithium ions increase. After research on the effect of temperature change on lithium batteries during charge and discharge, we found that ambient temperature affects the growth rate of cathode SEI film during cyclic charge-discharge. High temperatures will reduce cycle life and increase the risk of catastrophic failure. Conversely, low temperatures also limit battery life because the battery internal resistance increases. It is suggested charge battery at rated temperature which can extend using time. Especially for golf carts battery maybe charge 2 or 3 times a day.
