Energy storage battery testing standards

Recently, energy storage and power battery technologies have developed rapidly, driven by scientific breakthroughs and accelerated product applications. Various large-scale energy storage systems such as lithium batteries, flow batteries, and high-temperature sodium batteries have been applied and promoted globally. However, the pace of leading innovation and the recent battery-related fires have caused widespread concern around the world about the fire and electric shock hazards of lithium-ion batteries and other new technologies. Energy storage batteries mainly refer to batteries used in solar power generation equipment, wind power generation, and renewable energy storage energy.

Standard energy storage batteries are lead-acid batteries (lithium-ion energy storage batteries using lithium iron phosphate as the positive electrode material are being gradually developed)

Energy storage batteries are divided into the following three categories:

1 Lead-acid battery for exhaust-type energy storage-a battery with a device that can replenish liquid and release gas on the battery cover.

2 Lead-acid batteries for valve-regulated energy storage-each battery is sealed. Still, each battery has a valve that allows gas to escape when the internal pressure exceeds a specific value.

3 Lead-acid batteries for colloidal energy storage batteries that use colloidal electrolytes.
