How often does electric car battery change? Usually how to maintain it?
Do not change the charger arbitrarily, do not remove the controller's speed limit.Each manufacturer's charger generally has personalized needs, when not sure, do not change the charger at will. If continued long trip mileage requirements, we must charge to different places and with a number of chargers, the day complement chargers to add a separate charger, and the original use of the charger at night. Removing the speed limit of the controller, although it can increase the speed of some cars, will not only reduce the safety of the vehicle, but also reduce the service life of the battery.
Battery life 2-3 years!Experienced users know that battery costs are the biggest drain on electric bikes, so users are very concerned about prolonging battery life. First of all, assume that the charger has no problem, and whether the user is using it properly is vital to the life of the battery. The precautions for using batteries are as follows:
Protect the charger.The general instructions for use include instructions on how to protect the charger. Many users do not read the instructions of the habit, often in addition to the problem after thinking of looking for instructions, often too late, so the first look at the instructions is very necessary. In order to reduce the cost of the charger, now basically no design, high vibration resistance so that the charger is generally not on the electric bicycle and bicycle in the trunk. Special circumstances, you must move, but also the charger wrapped in foam plastic, to prevent vibration bumps. Many chargers after vibration, the internal potentiometer will drift, so that the entire parameter drift, resulting in abnormal state of charge. In addition, the need to pay attention to when charging is to maintain the ventilation of the charger, otherwise, not only affect the charger's life, but also may occur thermal drift and affect the charging state. This can cause damage to the battery. Therefore, it is also important to protect the charger.
Recharge every day.Even if you do not have the ability to continue, the charge can be used for 2 to 3 days, but it is recommended that you charge every day, so that the battery is in a shallow cycle, the battery life will be extended. Some early users of mobile phones think that the battery is best to be recharged after the basic use, this view is wrong, lead-acid battery memory benefit is not so strong. The battery life is greatly affected by the constant discharge of electricity. Most chargers charge the battery at 97% to 99% after the indicator lights indicate full power. Although only 1% to 3% of the electricity charge less, the added capacity of the line is almost negligible, but also due to the formation of charge accumulation, so after the battery is full or the lights change as much as possible to continue charging, is also beneficial to inhibit sulfide battery.
