Energy storage batteries mainly store electrical energy. It does not fluctuate as much as power batteries when supplying electricity externally. The batteries are considered to be a relatively smooth output. And generally, have a small discharge current and long discharge time. There is another requirement for batteries is long service life. Its service life is generally about 5 years.

The composition of the energy storage battery.
An energy storage battery is a whole composed of battery storage equipment (from single components → battery pack module → battery cabinet → battery storage unit → battery storage equipment), PCS, and filter links.

The history of energy storage battery development.
An energy storage battery is one of the core components of electric vehicles. To a large extent, it determines the performance of electric vehicles. Energy storage battery has gone through three generations of development, which are wrong battery, alkaline battery, and fuel cell.

One of the generations of lead batteries is inexpensive. But the number of charges and discharge is low, the self-discharge current is high, and the reaction speed is slow. The second generation of batteries is alkaline batteries. The common ones are nickel-tin batteries, town oxygen batteries, Ricoh batteries, etc. Among them, nickel couch battery contains heavy metal chromium, which seriously pollutes the environment. And the memory effect is stronger, now rarely used. In terms of capacity-to-volume ratio, a mirror hydrogen battery is twice higher as a mirror cadmium battery. And solve the problem of heavy metal pollution.

Daily maintenance

1) Timely cleaning and maintenance to eliminate hidden dangers. If you don’t use an electric car every day, you should pay attention to the cleanliness of the energy storage battery. Timely remove the dust and dirt on the battery cover, and keep it dry and clean to prevent the lithium battery from being uneven. Take out the copper green of the contact point between the battery pack charge and discharge port and charger in time to prevent poor contact from causing hidden trouble.

2) When it is not used for a long time, it can be charged normally. If your electric car is not used for a long time, you should avoid leaving the energy storage battery in a long-term power loss state, which will lead to a significant shortening of battery life. It is recommended to charge it once every two weeks and try to keep it in a half-charged state.

3) The storage location of the energy storage battery should be far away from dangerous sources. When daily parking, it should be stored in a ventilated place, so that the energy storage battery avoids the influence of a humid environment and long exposure to the sun. It should be away from heat sources and flammable and explosive substances.

Shenzhen BAK Technology Co., Ltd. has developed various kinds of energy storage cells. And we conduct a lot of tests before leaving the factory to ensure the quality. If you are in the battery business, you may consider using our cost-effective products.
