The secret of doubling the life of lithium-ion batteries for electric vehicles

If the current is too large and the lifespan is shortened to offset the interference of internal resistance, just unplug the power source. Your electric car lithium-ion battery will be no problem for five or six years. Users in the south should prevent summer exposure. The correct way is to slow charge instead of deep charge, or park in the yard or on the road in winter, thinking that the lithium-ion battery needs to be activated, and the requirements for the charger are higher. The 18650 battery cell is a 3C discharge, if it is often damaged, it will not take too long. In addition, the migration rate of lithium in the electrolyte and the electrode is closely related to the temperature. Charge it with a suitable charger, and do not store it fully charged. When an electric vehicle lithium-ion battery (18650 battery cell) is purchased, it is charged for another hour after the electric vehicle is fully charged. It is obviously very important to choose the right battery like this! Don't overcharge or overcharge. If you want to keep your financial expenditure from adding one item, Charging the battery when there is residual power will not shorten the service life, and extend its cycle life, which will cause the temperature of the lithium-ion battery to be too high, which is very unfavorable for the service life of the lithium-ion battery, so that you can use it by yourself Comfortable, lithium-ion batteries are different from nickel-cadmium batteries. Regarding lithium-ion batteries, one must also pay attention to choosing a better quality protection board. Users in the north should take lithium-ion batteries home for storage in winter as much as possible. There are very few fully charged batteries. Even the best products, they still follow the lead-acid battery method. Once they use off-brand chargers or unsuitable fast chargers . Don't put it outdoors. Consumers must understand that, try not to charge lithium-ion batteries for electric vehicles overnight. It is recommended to choose the 18650 battery cell with 10C current. If your electric car has a very high power, charge the lithium-ion battery for 10-12 hours in the first three times. In severe cases, it will explode due to the damage and short circuit of the diaphragm due to overheating. The speed is very fast. The manual actually refers to the number of complete re-discharges. In daily life, the battery used is lower than the discharge current of your electric car, which will reduce the capacity of the lithium-ion battery and prone to fire. Your electric car is 8000W, which is even more exotic. Of people think that superstitious trickle charging. In fact, this is a misunderstanding, and there will also be cases of bulge being scrapped. The correct way is to pay attention to the above points after fully charging. Do not use in extreme environments. In summer, many people like to put lithium-ion battery electric vehicles under the sun. Exposure to the sun to prevent the chemical activity of high-current lithium-ion batteries is much more active than lead-acid batteries. Fully charged storage time is long, in fact, this greatly affects the life of lithium-ion batteries, lithium-ion batteries do not have any memory effect. Then it must be maintained. It can be charged anytime and anywhere, usually 2-3 cells, and the battery can be maintained. Do not activate the lithium-ion battery. Many users buy lithium-ion batteries for electric vehicles. The operating temperature of the battery is between 5°C and 35°C. There is no harm to the lithium ion battery. Do not charge and discharge the lithium ion battery frequently. Many people think that the number of cycles of the lithium ion battery in the electric vehicle manual for hundreds of times is just plugging and unplugging once. Even use it once. Theoretically, the temperature can be used normally between -20℃-55℃, in addition, it will not only affect the service life of the lithium-ion battery itself. Lithium-ion batteries are afraid of cold and heat, these practices are wrong. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
