1, correctly grasp the charging time.
Under normal circumstances, the battery charging time is about ten hours, so it is necessary to avoid overcharging. When you are ready to travel, you should arrange charging on the way in advance to avoid excessive discharge of the battery due to insufficient power during driving, which will seriously shorten the service life of the battery.
2. Protect the mobile phone charger and try to avoid the knock and vibration of the charger.
In order to reduce the cost, the current mobile chargers are basically not designed with high vibration resistance. After many chargers are vibrated, the potentiometer inside them will drift, which will lead to the whole parameter drift and lead to abnormal charging. Therefore, if you must use a mobile charger, try to wrap it in plastic foam.
In addition, the charger should be ventilated when charging, otherwise it will not only affect the life of the charger, but also affect the charging state due to thermal drift and damage the battery.
3. It is forbidden to store the battery in the power-off state.
Because the battery is stored in a state of insufficient electricity, it is easy to be sulfated, and the lead sulfate crystal adheres to the electrode plate, which will block the ion channel, resulting in insufficient charging and decreased battery capacity. The longer the battery is idle, the more serious the battery damage is. Therefore, when the battery is idle, charging it once a month can better keep the battery healthy.
4. preheat the battery before going out
In winter, the electric car may still have 70% electricity the day before, but after a night, it found "leakage"!
In fact, this is not a "leak", but a "low temperature" disaster. When the electric vehicle is running, the battery is in a state of continuous discharge, and the battery will generate heat during the discharge process, so the battery itself is hot and the battery voltage is relatively high. So I see that there is still a lot of power left in the electric car.
But in the cold winter night, the battery has already cooled down and the voltage has dropped. At this time, BMS will automatically adjust the displayed power and cruising range, which is called "leakage".
