A tram charge typically takes eight to 10 hours to fully charge.
Charging time is best not more than 12 hours, easy to damage the battery, scientific charging can extend the life cycle of the electric car battery, when the electric car power use at about 70%, and then charge the electric car.
The following are the precautions for charging the charging pile:
1, first of all, comply with frequent charging shallow discharge. In terms of charging frequency, to keep the battery fully charged, do not charge when the battery power is less than 15% to 20%, excessive discharge will cause the battery inside the positive active substances, negative active substances are gradually converted into resistance, thereby reducing the battery life;
2. The difference between DC and AC charging modes. Dc and AC charging modes are also known as fast charging and slow charging because of different charging times. The way of fast charging is simple and rough direct current is directly stored in the power battery; Slow charging requires the car charger to convert AC to DC and then charge the power battery.
3, from the point of view of the charging mode, whether fast or slow charging, the principle of charging is the process of transferring the lithium ions of the positive electrode of the cell to the negative electrode under the action of external electric energy, and the difference between fast charging and slow charging is the speed of the lithium ion migration of the positive electrode of the cell during the charging process. In the usual car, the battery can be polarized at a normal speed by the alternate use of slow charge and fast charge, and the battery life can be extended.
