How to protect electric vehicle batteries and chargers?

Date:May 23, 2019

Even the best electric cars can't afford the wear and tear of inferior chargers and batteries. If you want to ride electric cars for a long time, you need to pay more attention to the advantages and disadvantages of electric cars and chargers. In order to better protect the electric car, Xiao Bian summarized the skills of the top ten protection batteries and chargers, hoping to help everyone. 1. Do not use inferior chargers. The voltage and current of inferior chargers are sometimes unstable, and the heat dissipation is poor. Frequent use not only causes damage to the battery, but may also cause a fire.

2. Do not replace the charger at will. In general, the original charger and battery are best. The charger parameters for different electric vehicles are basically the same, so you need to change them carefully.

3, the charger should not be bumpy for a long time. The charger is not resistant to strong vibrations, so the charger should not be placed in the trunk and basket of the electric bicycle. Generally, chargers are rarely used badly, and most of them are bumpy during riding. The charger can be packaged in foam to prevent vibration and bumps. 4, develop the habit of charging every day. There are a lot of people who have been charging for 2-3 days without charging, which causes the battery to be in a deep discharge condition. This is very bad, and the battery life is greatly reduced! It is recommended that you charge every day and the battery life will be extended.

5, after the full charge, then go on the road. Most people think that the charger is full after the indicator light has changed color. In fact, this is not the case. It is not full of true meaning. Therefore, after the battery is fully charged and turned green, it will be charged for a little while to prevent the battery from being vulcanized.

6. Perform deep discharge periodically. This can also be understood as the fact that the battery is not charged at all, and it is not performed regularly. Regular deep discharge, the battery is fully discharged once a week is also beneficial to "activate" the battery, which can slightly increase the battery capacity.

7, the charging environment should be stable. The best ambient temperature for charging is 20-28 °C. In addition, as the weather does not pass, the charging situation is different, charging in winter or summer, there will be overcharge or undercharge. So try to ensure a safe and stable charging environment. 8, to avoid high temperature exposure of the battery. The environment with too high temperature will increase the internal pressure of the battery, and the battery pressure limiting valve will be forced to open automatically. The direct consequence is to increase the water loss of the battery. The excessive water loss of the battery will inevitably lead to a decrease in battery activity, accelerate the softening of the plates, heat the casing during charging, and cause fatal damage to the casing due to drums and deformation. This can easily lead to unsafe events during the charging process.

9, ride to learn to save electricity. When encountering a red light or going downhill, try to use the early power-off slide to reduce the brakes as much as possible. When starting, slowly turn the handle to avoid the impact of large current on the battery, and can reduce the battery's power loss and life damage. In addition, acceleration and braking should not be used together.

10. Charge first connect the battery and then power on. Due to the large charging current of the battery, a large surge current is generated when the power is first inserted and then inserted into the battery. Excessive inrush current easily damages the charger and affects the service life of the battery.
