What are the correct ways to use lithium battery electric vehicles?

1. Do not change the charger casually, do not remove the speed limit of the controller. Chargers from various manufacturers generally have individual requirements. Do not change the charger at will when you are not sure. If the continuation mileage is relatively long, it is necessary to equip multiple chargers for charging in different places. The chargers for supplementary charging in the daytime should be supplemented with chargers, and the original chargers should be used at night. Removing the speed limit of the controller can increase the speed of some cars, but in addition to reducing the safety of the car, it will also reduce the service life of the battery. 2. Protect the charger. There are instructions on protecting the charger in the general operating instructions. Many users do not have the habit of reading the manual, and 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 costs, the current chargers are basically not designed with high vibration resistance. In this way, the chargers are generally not placed in the trunk and basket of the electric bicycle. In special cases where it is necessary to move, the charger should also be packed with foam to prevent vibration and bumps. After many chargers undergo vibration, their internal potentiometers will drift, causing the entire parameters to drift, resulting in abnormal charging status. Another thing to note is to keep the charger ventilated when charging, otherwise it will not only affect the life of the charger, but also may cause thermal drift and affect the charging state. This will damage the battery. Therefore, it is also very important to protect the charger. 3. Charge it every day Even if your battery life is not long, you can use it for 2 to 3 days with a single charge, but it is recommended that you charge it every day, so that the battery is in a shallow cycle state and the battery life will be prolonged. Some early mobile phone users thought that it is best to charge the battery after the battery is basically used up. This view is wrong. The memory benefit of lead-acid batteries is not that strong. Frequent discharge of electricity has a greater impact on the life of the battery. In most chargers, after the indicator light changes to indicate a full charge, the battery charge may be 97% to 99%. Although only 1% to 3% of the battery is under-charged, the impact on continuity is almost negligible, but under-charge accumulation will also be formed. Therefore, after the battery is fully charged and changed to light, continue to float charge as much as possible, which is also useful for suppressing battery vulcanization. have benefits. 4. The vulcanization process started after the rechargeable battery was discharged in time, and obvious vulcanization appeared after 12 hours. Charging in time can remove non-serious vulcanization. If it is not charged in time, these vulcanized crystals will accumulate and gradually form coarse crystals. The general charger is powerless to these coarse crystals, which will gradually reduce the battery capacity and shorten the time. The service life of the battery. Therefore, in addition to daily charging, we must also pay attention to charging as soon as possible after use, so that the battery power is as full as possible. 5. Regular deep discharge of the battery Regular deep discharge is also beneficial to activate the battery, which can slightly increase the battery capacity. The general method is to fully discharge the battery periodically. The method of full discharge is to ride the bike under normal load conditions on a flat road to the first undervoltage protection. Note that we especially emphasize the first undervoltage protection. After the battery is under voltage protection for the first time, after a period of time, the voltage of the battery will rise and return to a non-undervoltage state. At this time, if the battery is used again, the battery will be seriously damaged. After the complete discharge, the battery is fully charged. You will feel that the battery capacity has improved.
