Therefore, charging an electric vehicle every day has little impact, and it is best to develop the habit of charging whenever needed, especially avoiding waiting until the battery is completely depleted before charging, otherwise it may directly shorten the battery's lifespan.
In addition, it's crucial to manage the charging time carefully, as prolonged charging can cause the battery pack to bulge, and in severe cases, even spontaneous combustion. Therefore, it's essential to control the charging time. Batteries are vital for new energy vehicles, and only by mastering the correct charging methods can battery life be extended. Below, we'll introduce some correct charging methods for new energy vehicles.
1. Shallow charging and shallow discharging
When charging new energy vehicles, it's not necessary to fully charge them every time. The best approach is to charge as needed, using a shallow charge and discharge cycle. Maintaining the battery level between 20% and 90% is sufficient. This is especially important for daily commutes within the city; simply charging enough to cover the required distance is enough, which will significantly extend battery life.
2. Try to choose slow charging.
Because fast charging is very fast, it can usually fully charge a car in about an hour, so many car owners prefer to choose fast charging, and fast charging does indeed meet the needs of car owners. However, from the perspective of battery life, slow charging is more beneficial to extending the battery's lifespan. This is because slow charging uses low-voltage AC power, which is a relatively mild and slow chemical reaction. It can not only maintain the battery but also reduce the battery's "spontaneous combustion rate".
3. Avoid excessive discharge
Especially for vehicles that are left unused for extended periods, it's essential to recharge them regularly, typically once a month. This is because the battery will discharge if the vehicle is left unused for a long time, leading to severe battery depletion and impacting its lifespan. Therefore, even if the vehicle is not in use, it should be charged monthly.
4. Avoid charging at high temperatures.
Whether it's a lithium battery or a lithium iron phosphate battery, charging at high temperatures will shorten the battery's lifespan. Therefore, in hot summer conditions, it's best to choose a cool, well-ventilated place to charge the battery.
