Classification of energy storage batteries

　　The common energy storage battery is lead acid battery (lithium ion energy storage battery with lithium iron phosphate as cathode material is being developed gradually at present).

　　Energy storage batteries are divided into the following three categories:

　　1 Vented lead-acid battery for energy storage - battery with a device capable of replenishing liquid and separating gas on the battery cover.

　　2 Valve regulated lead-acid battery for energy storage Each battery is sealed, but has a valve that allows gas to overflow when the internal pressure exceeds a certain value.

　　Lead acid battery for colloid energy storage - battery using colloid electrolyte.

　　Lead acid batteries for energy storage must have the following characteristics

　　1 The temperature range of use is relatively wide, and it is generally required to operate normally in a temperature environment of - 30-60 degrees.

　　2 The low temperature performance of the battery is good, and it can be used even in areas with low temperature.

　　3 The capacity shall be consistent, and shall be consistent in the use of batteries in series and parallel.

　　4 Good charging acceptance. In an unstable charging environment, it has stronger charging acceptance ability.

　　5. Long service life, reduce repair and maintenance costs, and reduce overall system investment.
