Optimal charging range for ternary lithium batteries
The optimal charging range for ternary lithium batteries is 20%-80%. When the battery level drops to approximately 20%, it should be charged promptly to extend its lifespan. Additionally, unless otherwise specified, it's best to stop charging ternary lithium batteries when they reach 80%-90%. Overcharging can lead to overcharging, which will also negatively impact battery performance and lifespan.
In addition, the current fast charging range for new energy vehicles is 30%-80%. When the battery is charged to 80%, the battery temperature is very high, and the charging power will start to drop significantly. Usually, it only takes half an hour to charge a ternary lithium battery from 30% to 80%, but it takes 20 to 30 minutes or even longer to charge from 80% to 100%, which is not cost-effective in terms of time.
The correct way to charge a ternary lithium battery
Regarding the correct method for charging ternary lithium batteries, if it is a single ternary lithium battery, then you can directly charge it with the matching charger. However, you still need to pay attention to the following:
1. Try not to completely drain the ternary lithium battery before recharging. When you notice that the performance of your device is starting to decline, it means that the battery is low and you should charge it.
2. During the charging process of ternary lithium batteries, avoid frequent charging and discharging. That is, do not continue using the battery while it is charging and then recharge it. Try to fully charge the battery in one go.
3. It's okay to occasionally use up all the power in a ternary lithium battery, but you must charge it immediately. If the battery is left in a depleted state for a long time without being charged, it will have a significant impact on the battery's performance and lifespan.
As for the correct charging method for ternary lithium batteries specifically for new energy vehicles, it is actually similar to that for single-cell batteries. In daily use, you should try to avoid completely depleting the power battery before recharging. It is best to keep the power level above 20% before charging.
Furthermore, if there are no abnormalities during charging, try not to frequently plug and unplug the charging gun. When the battery is low, charge it promptly and avoid leaving it in a discharged state for extended periods. To maximize battery lifespan, it is recommended to primarily use slow charging, supplemented by fast charging.
