1. How to charge a new battery for the first time?
It is recommended to recharge the battery with 30% remaining, so as to avoid voltage difference due to over-discharge of the battery. The charging time should be controlled within 8~12 hours, and the charging time in summer should be shortened accordingly. Generally, the charger can float for 1~2 hours after the green light turns, and it is not allowed to charge for a long time. If the battery is not used every two or three months, the battery must be deeply charged and discharged to avoid the power precipitation and affect the battery capacity.
2. Will the battery life be affected when the electric vehicle is driven in rain?
Long-term immersion in water will definitely affect the battery. On the one hand, the line is damp and rusty, which will increase the resistance, increase the power consumption of the electric vehicle, shorten the battery discharge time, and cause the mileage to be insufficient. Therefore, try not to let the electric vehicle run for a long time. Get in the rain.
3. When the battery is fully charged, why is the riding distance less than 10 kilometers?
After this happens, don't immediately think it is the cause of the battery. It is possible that there is a problem with the electric vehicle charger parameters and the battery is not fully charged. It is also possible that the instrument has a problem or the battery capacity is reduced, the battery line will be dashed, and the motor bearing will wear out.
4. What is the problem with the charger not turning the lights
The fact that the charger does not turn on the lights is not necessarily the cause of the charger. It is usually caused by the following factors: the battery lacks electrolyte, the charging environment temperature is too high, the charging circuit is aging, and the charger parameters do not match.
