Energy storage battery

Energy storage batteries mainly refer to batteries used in solar power generation equipment, wind power generation equipment and renewable energy storage energy.

Classification of energy storage batteries

The common energy storage battery is a lead-acid battery (a lithium-ion energy storage battery with lithium iron phosphate as the positive electrode material is being gradually developed).

Energy storage batteries are divided into the following three categories:

1 Lead-acid battery for vented energy storage - a battery with a device capable of rehydration and gas evolution 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 escape when the internal pressure exceeds a certain value.

3 Lead-acid batteries for colloidal energy storage - batteries using colloidal electrolytes.

Features of energy storage battery

Lead-acid batteries for energy storage must have the following characteristics

1 The temperature range used 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 better, and it can be used even in areas with relatively low temperature.

3 The capacity consistency is good, and the consistency is maintained when the batteries are used in series and parallel.

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

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