What are the maintenance methods for lithium iron phosphate batteries for electric vehicles

In the course of use, the charging time should be accurately grasped according to the actual situation, and the frequency of charging should be grasped with reference to the usual frequency of use and mileage. During normal driving, if the electricity meter indicates that the red and yellow lights are on, it should be charged; if only the red light is left on, stop running and charge as soon as possible, otherwise the battery will be over-discharged and its life will be seriously shortened. After fully charged, the running time is short, and the charging time should not be too long, otherwise it will cause overcharging and make the battery heat up. Overcharge, overdischarge and undercharge will shorten the battery life. In general, the average charging time of lithium iron phosphate batteries is about 10 hours. If the battery temperature exceeds 65°C during the charging process, stop charging. 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. Under special circumstances, it must be moved, and the charger must 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. Regular deep discharge of the battery Regular deep discharge is also beneficial to activate the battery, which can slightly increase the capacity of the battery. The general approach is to fully discharge the battery periodically. The way to completely 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. 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 think that it is best to charge the battery after the battery is basically used up. This view is wrong, and the memory effect of the battery is not so 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 the continuation ability 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. It is strictly forbidden to lose power during storage. The battery is strictly prohibited to lose power during storage. The state of power loss means that the battery is not charged in time after use. When the battery is stored under the power-deficient state, sulfation is easy to occur, and the lead sulfate crystals adhere to the electrode plate, which will block the electric ion channel, resulting in insufficient charging and a decrease in battery capacity. The longer the idle time in the power-deficient state, the more severe the battery damage. Therefore, when the battery is not in use, it should be recharged once a month to better maintain the battery health.
