Six tips for electric car battery maintenance

The life and safety of electric vehicle battery is the most important concern of consumers. Once it is used improperly, it can easily cause spontaneous combustion of the battery and even fire and explosion. The safety is worrying. In fact, as long as you master certain common sense of daily use, you can avoid similar tragedies. How do electric car owners correctly master the charging and maintenance methods?

First, protect the charger. The general instructions for use have instructions for protecting the charger. Many users do not have the habit of reading the manual. They often think of looking for the manual after the problem. It is often too late, so it is very necessary to read the manual first. In order to reduce the cost, the current chargers basically do not have a high vibration-resistant design, so that the charger is generally not placed in the trunk and basket of the electric bicycle. In special cases, it must be moved, and the charger should be packaged in foam to prevent bumps. After many chargers are vibrated, their internal potentiometers will drift, causing the entire parameters to drift, resulting in an abnormal state of charge. Another thing to note is that the charger should be kept ventilated during charging. Otherwise, it will not only affect the life of the charger, but also cause thermal drift and affect the state of charge. This will cause damage to the battery. Therefore, it is very important to protect the charger.

Second, correctly grasp the charging time. In the case of normal driving, if the red and yellow lights of the electricity meter are on, it should be charged; if the yellow light is off, only the red light is on, stop charging as soon as possible, otherwise the battery will be over-extended. Discharge and shorten life. Some people are used to charging every time they go out, sometimes only after a short period of time to recharge, this time charging time should not be too long, otherwise it will overcharge and make the battery heat. Under normal circumstances, the average charging time of a car battery is about 10 hours. Overcharging, over-discharging and insufficient charging will shorten the battery life. If the battery temperature exceeds 65 ° C during charging, stop charging immediately.

Third, avoid plugging heat when charging. The 220 volt power plug or charger output plug is loose, the contact surface is oxidized, etc., which will cause the plug to heat up. If the heating time is too long, the plug will be short-circuited or contact poorly, which will damage the charger and the battery and cause unnecessary loss. Therefore, when the above situation is found, the oxide should be removed or the connector replaced.

Fourth, it is strictly forbidden to expose to the sun. A battery that has been exposed to sunlight will lose water due to an increase in internal pressure, causing a decrease in battery activity and accelerating aging of the plates.

Fifth, charge every day. Even if your continuation ability is not long, you can use it for 2 to 3 days, but it is recommended that you charge every day, so that the battery is in a shallow cycle and the battery life will be extended. Some early users of mobile phones think that it is better to recharge the battery after it has been basically used up. This view is wrong. The memory efficiency of lead-acid batteries is not so strong. Frequent discharge of electricity has a greater impact on the life of the battery. Most chargers may charge 97% to 99% of the battery after the indicator light is fully charged. Although only undercharged 1% to 3% of the power, the impact on the continuation ability is almost negligible, but it will also form undercharge accumulation, so after the battery is fully charged, it will continue to float as much as possible, to suppress the battery vulcanization. beneficial.

Finally, during the driving process, you should try to avoid slamming and accelerating, and the high current discharge at the moment of the trip. When an electric car starts, manned, or goes uphill, if it is stepped on, it will form an instantaneous high-current discharge. Large current discharges tend to cause the formation of lead sulfate crystals, which impair the physical properties of the battery plates. If there is a sudden drop in speed of several tens of kilometers during driving, be careful that there may be a problem with a certain battery and should be checked as soon as possible.
