Analysis of charging methods and precautions for lithium batteries of electric vehicles

1. Don't charge in the sun in hot weather. You can't charge immediately after driving in summer. Pay special attention to this. Remember not to charge the electric car in the hot sun, and do not expose the rechargeable battery to the sun. The same principle, whether it is normal or when charging the battery, must eliminate the use of fire and pyrogens. 2. The electric vehicle is reminded that there is insufficient power during the driving process, and the battery should be charged as soon as possible. The vulcanization just started after the rechargeable battery was charged and discharged, and significant vulcanization occurred within 12 hours. Moderate filling can eliminate non-serious vulcanization. If it is not filled immediately, this vulcanized crystal will slowly accumulate and thick crystals will appear. Therefore, in addition to daily filling, pay attention to it and fill it as soon as possible afterwards. Try to make lithium The power consumption of the battery pack is in the filling condition. 3. Do not use a unique method to stimulate the lithium battery. When a pure electric vehicle is driving, the lithium battery will naturally stimulate the voice. There will be no memory, no intentional deep battery charging and activation. Fourth, to ensure that a suitable lithium battery charger is used for charging, first insert the charger output plug into the battery charging socket, and then plug the charging head into the voltage socket, and observe the indicator light to distinguish whether the battery is charging. If the charging head is lost or damaged, please contact the relevant agent to purchase. Do not use lead-acid battery charging heads or other charging head batteries to charge. 5. Generally, charge the battery for about 1-2 hours after the charger indicator turns green to terminate the battery charging. Lithium battery rechargeable batteries have no memory. Each time the battery is charged, it takes about 5-8 hours. The user should estimate the time when using it to prevent overcharging. Sixth, as far as possible to promote the use of lithium battery packs at any time, to prevent each rechargeable battery under voltage protection and then recharge the battery, which can further improve the life of the rechargeable battery and make the rechargeable battery in a shallow cycle system. The life of the rechargeable battery. 7. Prevent high-temperature charging. Do not charge the battery in a natural environment where the temperature exceeds 40°C. High temperature will reduce the battery power. Try to choose a natural environment that is cool and naturally ventilated. A natural environment that is too hot is unfavorable for battery charging and will continue to destroy rechargeable batteries and reduce their service life. The best working temperature for lithium battery charging is 25°C. At this stage, most charging heads do not have the automatic control system software integrated into the working temperature. Most charging heads are designed according to the working temperature of 25°C. Therefore, the actual effect of battery charging under the standard of 25°C is stronger. 8. If electric vehicles are not used for a long time, the rechargeable battery should be disconnected from the whole vehicle, and the rechargeable battery should be filled with some power in a certain interval to prevent the life of the rechargeable battery lithium battery. Lithium batteries cannot be stored with empty electricity. If lithium batteries cannot be used for a short time, please charge them above 50% before they can be stored, and be sure to fill up rechargeable batteries every month. 9. When charging the battery, if the charger plug continues to heat up and it takes a long time to be hot, you should immediately check whether the power plug is short-circuited or poorly contacted, and the charging head should be pulled out to check whether the power plug is on top There are metal oxides, such as rust, which will be eliminated immediately.
