Safety strategy for rapid charging of electric vehicle batteries

For a long time, the charging safety and service life of electric vehicle batteries have been the focus of attention. How to charge car batteries faster and safer? Today, an electric car lithium-ion battery case expert teaches you: Six safety tips for fast charging of electric car batteries Charge as much as possible every day, although the battery can be used after a full charge 2 -3 days, but we recommend charging every day. This can make the battery form a shallow cycle, and the battery life is more guaranteed. At the same time, prevent the battery from being charged after the light is released. Most charger replacement indicators show that after fully charged, the battery power can reach 97%~99%. Although only 1%~3% of the battery is insufficient, the impact on battery life is negligible, but it can also lead to the accumulation of insufficient battery. Therefore, after the battery is fully charged, the floating charge can still be continued, which is also beneficial to inhibit the curing of the battery. 2. Correct charging time Under normal driving conditions, when the meter indicator is red and yellow, you should charge; when the yellow light is off and the red light is on, you should stop charging as soon as possible, otherwise the battery life will be shortened due to excessive discharge. Generally speaking, the average charging time of a car battery is about 10 hours. Overcharge, overdischarge, and overcharge will shorten battery life. If the battery temperature exceeds 65°C during charging, stop charging immediately. 3. Prevent the hot plug 220v power plug or charger output plug from loosening during charging, and the phenomenon of contact surface oxidation will cause the plug to heat up. If the heating time is too long, it will cause the plug to short circuit or poor contact, damage the charger and battery, and bring you Unnecessary losses. Therefore, when the above situation is found, the oxide should be removed or the connector should be replaced in time. 4. There are instructions to protect the charger in the general manual of the charger. Many users don't have the habit of reading the manual, and it is often too late except for the problems of looking for the manual in the future, so it is necessary to read the manual. In special cases, movement is necessary, but the charger should also be wrapped in foam to prevent vibration and turbulence. Pay attention to keeping the charger ventilated when charging, otherwise it will not only affect the service life of the charger, but also may cause thermal drift and affect the charging state. 5. Prevent instantaneous large-scale discharge. During driving, try to prevent stepping on the accelerator and high-current discharge at the moment of stroke. When an electric vehicle starts, carries people, or climbs a slope, if the acceleration is stepped on, it will form an instantaneous large current discharge. High current discharge can easily lead to lead sulfate crystallization and damage the physical properties of the battery panel. During driving, if you suddenly decelerate for tens of kilometers, be careful. It may be a battery problem and you should check it as soon as possible. 6. Do not expose to the sun. Many of us understand that electronic products should generally not be exposed to sunlight, because exposure of the battery to the sun will increase internal pressure and water loss, resulting in a decrease in battery activity, accelerating the aging of the board, and accelerating the aging process. The battery life of electric vehicles. Disclaimer: Some pictures and content of the articles published on this site are from the Internet. If there is any infringement, please contact to delete.
