10-12 degrees.
Large car batteries should range from a minimum of 150A to a maximum of 200A. There are 150A, 165A, 180A and 200A. Except for engineering machinery, other vehicles that can use 200A can only use 180A. However, the sizes of the three models of 150, 165 and 180 are the same. flippantly. It is recommended that the bigger the better in the northern region, a good start to winter. Lithium batteries can operate normally between -40°C and +75°C, while your car battery temperature is OK between -30 degrees and 50 degrees.
Can be used for 6 to 7 years.
The most commonly used ternary lithium batteries and iron phosphate batteries are currently in use. Battery life is related to the number of charges and discharges and the duration of wet storage. battery charge cycleternary lithium The number of times is 600-1000 times, and the number of charging cycles of iron phosphate batteries is 2000 times. The service life is 5-8 years, which is also related to the depth of discharge, humidity and other factors. Generally speaking, the lifespan can reach 6 to 7 years.
Battery life is closely related to how you usually use the car. Road conditions, vehicle condition and cargo capacity are also important. The better the road conditions and the car, the longer the battery life will be. Battery life is not absolute. If you feel that the car has no power, the battery life is short, the battery is swollen and hot or cannot be charged, you should replace it.
How to extend the lifespan of new energy electric trucks?
First of all, don't wait until the battery is almost dead to charge. Charge as you go and always keep the battery active.
Second, drive at a constant speed to protect all three electrical systems. Finally, if the battery is not used for a long time, it should be charged frequently. If the battery is exhausted, battery life will be reduced.
