AI Customer ServiceThe negative derati ng factors indicate the decreasing of the rate of capacity loss according to Equation (3). Therefore, the temperature can be derated to reduce the rate of capacity loss and prol on g battery calendar life. Calendar life can also be improved by derating the SOC. The cap acity losses at 140 days under are plotted in Figure 3a.
Temperature also affects service life of a battery. Battery performs best at room temperatures. If temperature is increased to 30°C for a long duration of time, service life of the battery reduces by 20 percent. While at 45°C, the life-cycle is reduced considerably to 50 percent. Like humans, batteries function best at room temperature.
exhibited two distinct derating modes depending on temperature. One was that the derating factor C). The other was that the 1.20 by derating the SOC to 0% under room temperature. The study implies LCO batteries. However, the rate of capacity loss for LFP batteries is only slightly declined by derating the SOC to 50% under high temperature. life.
The derating temperature. Under temperatures below 45 0.75. Therefore, the charge cut-off current can be derated under high temperatur e battery life, as presented in Figure 11 b. In addition, the discharge C-rate has little influence on derating discharge C-rates. C). At high
On the contrary, lower temperature increases internal resistance and reduces the rate of chemical metabolism, and thus results in a decrease in the capacity of the battery. If a battery’s capacity is 10o% at 27°C , it lowers significantly to 50 percent, once temperature is 18°C. At freezing point, the capacity of the battery reduces to 20 percent.
Operating a battery at elevated temperatures improves performance but prolonged exposure will shorten life. As all drivers in cold countries know, a warm battery cranks the car engine better than a cold one. Cold temperature increases the internal resistance and lowers the capacity.
