Don't replace the charger of
Used Electric Car casually, and don't remove the speed limit of the controller. Chargers of various manufacturers generally have personalized requirements. Don't replace the charger casually when you are not sure. If the control computer board requires a long range, it must be equipped with multiple chargers for charging in different places. The charger that is charged during the day should be used with another supplementary charger, and the original charger should be used at night. Although removing the speed limit of the controller can increase the speed of some vehicles, it will not only reduce the safety of the vehicle, but also reduce the service life of the battery.
Generally, there are instructions on protecting the charger in the instruction manual. Many users do not have the habit of reading the manual. They only think of looking for the manual after some simple problems occur, so it is very necessary to read the manual first. In order to reduce costs, chargers are basically not designed to withstand high vibration, so chargers are generally not placed in the trunk and basket of electric bicycles. In special circumstances, it is necessary to move, and the charger needs to be packed with foam plastic to prevent vibration and bumps.
Even if your range requirement is not long and you can use it for 2 to 3 days after charging once, it is still recommended that you charge it every day, so that the battery is in a shallow cycle state and the battery life will be extended.
The sulfidation process begins after the battery is discharged. After 12 hours, obvious sulfidation appears. Timely charging can prevent serious sulfidation. If it is not charged in time, these sulfidation crystals will accumulate and gradually form coarse crystals. General chargers are powerless against these coarse crystals, which will gradually cause the battery capacity to decrease and shorten the battery life. Therefore, in addition to charging every day, you should also pay attention to charging as soon as possible after use to keep the battery in a full state as much as possible.
