The power battery is the heart of the new energy vehicle and the most expensive equipment of the vehicle. The general service life of the battery is 10 to 15 years, and the replacement of the power battery is the most expensive maintenance project. Therefore, the correct use of batteries is very important to extend the service life of new energy vehicles and reduce maintenance costs.

At present, there are no more than two ways of charging new energy vehicles: DC fast charging and AC slow charging.

The fast charge is the charging interface of the DC charging pile, which converts the alternating current of the power grid into direct current, which is transmitted to the fast charge port of the electric vehicle, and the electric energy is directly charged into the battery.

Fast charging port
Slow charge is the charging interface of the AC charging pile, which inputs the alternating current of the grid into the slow charge port of the electric vehicle, converts the alternating current into direct current through the charger inside the car, and completes the charging in the input battery.

So, how should electric cars be charged? How to charge to extend the battery life?
Try to choose a slow charge
In daily use, it is best to charge regularly, maintain good charging habits, and choose a reasonable charging mode. The current and power required for fast charging are relatively large, which may cause the temperature of the battery pack to rise too fast, and the module battery cannot be evenly charged, which will reduce the service life of the battery. Although the slow charge is full, the current and power required by it are not high, and the damage to the battery itself is not so great. Especially for new energy vehicles that are newly purchased and not opened for a long time, small current and slow charging mode should be adopted at the beginning. In the case of no hurry, it is recommended to choose slow charging as far as possible.
Don't charge the battery too full or for too long
Simply put, do not use electricity too much, the daily electricity is often maintained between 20% and 80%, with charge. When the battery is not fully discharged, frequent charging will not affect its capacity and life, but can maintain the activity inside the battery and extend the cycle life of charging. (Same as cell phone battery use)
Prevent overexposure and explosive cold
Exposure to strong light will increase the internal pressure of the battery, resulting in decreased activity and accelerated aging. In extremely cold temperatures, the activity of the battery will also be adversely affected, resulting in reduced battery life. Under normal circumstances, the better charging temperature should be between 0 and 45 degrees, such as below zero, it is recommended not to do fast charging in extreme conditions, you can first use slow charging to keep the battery in a good state, and finally to do fast charging will be better.
Check whether the charging gun and the charging port are clean before charging the electric car between, be sure to check these, do not have stains, mud or snow stuck on it, which is not good for the electric car. There is also a thunderstorm, even if you are in a hurry, you must not charge the electric car, because this is a very risky thing.
Well, if the car is in the charger, it is definitely better to charge slowly, because if the car charger is used fast, the consumption of the battery may be relatively large, and it is easy to damage and damage a battery of the car, because your instantaneous output current is too large, it may also cause the car to fluctuate and lead to the car may run unsmoothly. Any of the reasons that might not reach the fire could happen.
Car charger or slow charge, can effectively protect the phone.
