Precautions for maintenance of electric vehicle batteries:
1. Correctly arrange the charging time.
Generally, the battery charging time is about 10 hours. Please avoid overcharging. When preparing for a long-distance trip, arrange for charging on the way to avoid insufficient power during driving, which will cause the battery to over-discharge and seriously shorten its life.
2. Protect the portable EV charger.
If the charger is jolted and vibrated for a long time, its internal potentiometer may move, resulting in inaccurate parameters and abnormal charging. Therefore, it is recommended to bring a portable charger and protect it with soft packaging. Don't shake it too much. When charging, pay attention to the ventilation of the charger.
3. Frequent charging.
can not be idle for a long time without charging, this is conducive to the shallow cycle of the battery and prolong the battery life. Perform a deep discharge on the battery regularly to activate the battery.
4. Shortage of electricity when stored strictly.
When the battery is stored in the state of power loss, sulfation is prone to occur. The lead sulfate crystalline material adheres to the electrode plate, which will block the ion channel, and the car will be insufficiently charged and the battery capacity will decrease. The longer the idle time is, the more serious the battery damage is. Therefore, when the battery is not in use, it should be replenished once a month to better maintain the battery health.
5. Avoid high current discharge.
When an electric vehicle starts, carries people, and goes uphill, try to avoid slamming and accelerating, resulting in instantaneous large current discharge. High-current discharge can easily lead to lead sulfate crystals, thereby destroying the physical properties of the battery plates.
6. Prevent exposure in the sun and extreme cold.
If an electric car explodes in the sun for a long time, it will increase the internal pressure of the battery and cause the battery to lose water, causing the battery to deteriorate and accelerate the aging. And if it is an extremely cold temperature, it will also adversely affect the activity of the battery.
