Reasons for premature aging of electric vehicle battery life

1. The car owner has no awareness of battery maintenance, causing serious damage to the
battery. You have to wait until the battery can’t run before repairing and maintaining
it. At this time, repairing becomes more difficult. In fact, if the maintenance is
performed once every 6 months, the life expectancy will be extended a lot, but the car
owner does not have this awareness. Most of the battery damage starts from excessive
water loss caused by the charger.

2. The charger is the killer. Divided into inferior chargers and aging chargers, these
battery killers generally play a killer role after the battery 8 months. The reason is
that the new battery meets the taste of these battery killers. As the battery ages, the
battery can no longer meet the killer’s requirements. By June of each year, the battery
quickly loses water and becomes scrapped.

3. The high starting current of luxury electric vehicles causes battery vulcanization.
If the car owner starts the car and accelerates slowly, the battery life and mileage
will naturally increase by 20%.

4. The motor controller is damaged, causing the battery to be short-lived. The
probability is not high, but there are many.

5. There is no loss of electricity when riding, and the life is naturally long. The new
battery can be charged every time the electricity is used above the red light, but it
cannot be driven without power. Every time you lose power, the lifespan will be
shorter, and the new battery will soon be scrapped after 10 times of power loss. Charge
it in time to avoid power loss.

6. The most important point is to charge reasonably: Some people say, “The battery is
not worn out but charged.” This statement is really correct. The charging performance
of the battery plays a decisive role in the service life and performance of the
battery, so the charging method must be paid attention to. According to the situation
of most users, the best option is to charge the battery once at a depth of discharge of
50%-70%, so that the battery life can reach the best effect. At the same time, the
temperature has a considerable influence on charging. In the high temperature season,
the battery has the problem of overcharging. The temperature of the battery should be
reduced as much as possible to ensure good heat dissipation, and to prevent charging
immediately after exposure to the sun. Exposure to the sun will increase the
temperature of the battery and increase the activity of various active materials in the
battery, which will affect the service life of the battery. On the contrary, under low
temperature conditions, the battery has the problems of poor charging acceptance and
insufficient charging. In this case, it is necessary to increase the charging voltage
and prolong the charging time, and take heat preservation and antifreeze measures, so
as to ensure sufficient charge. Extend battery life.
