Lead-acid battery thermal runaway failure analysis when the battery is in the state of charge

Sep , 04 2023

Lead acid battery thermal runaway fault analysis When the battery is charged: There is a cumulative increase in battery temperature. When the heat accumulates to a certain extent during the warming process, the battery terminal voltage will suddenly decrease, forcing the current to increase suddenly, and the phenomenon of high battery temperature and damage to the battery is called thermal runaway...

Why only online UPS topology provides mission critical load protection

Sep , 09 2023

Why does only online UPS topology provides mission critical load protection? Modern, static UPS systems are broadly classified into three design architectures: on-line, off-line and line interactive. This post describes and compares the three types and explains why – for truly critical loads – online ups topology is the only acceptable approach. Facility executives today face increased demands for...

How do lithium batteries screen distribution groups?

Sep , 19 2023

The inconsistency between single batteries often causes problems such as too fast capacity decay and short life during the cycle of battery packs. Improving the consistency of batteries is of great significance to the popularization and application of lithium-ion batteries. 1 Inconsistency analysis Definition of inconsistency The inconsistency of the lithium-ion battery pack means that after the s...

Micropore system anatomy of AGM clapboard

Oct , 11 2023

The performance characteristics of VRLA batteries are largely determined by the capillary characteristics of the AGM separator, that is, the ability to keep the micropores in the thickness direction of the separator filled with electrolyte and prevent the electrolyte from drying out and causing delamination. These properties are influenced by the micropore structure, especially the micropore distr...

The role and importance of AGM partitions

Oct , 19 2023

AGM separator and transfer reaction between positive and negative plates Structure and function of partitions The AGM partitions used by VRLA have the following additional functions: Absorb the electrolyte (the third active substance of the battery) so that it does not flow. Provides a relatively large gas transfer hole for oxygen diffusion and thus facilitates the operation of the COC. High ionic...

Method for providing the service life of valve-controlled closed lead acid Battery (VRLA)?

Nov , 03 2023

1 Temperature affects battery life: thermal runaway causes temperature rise: Valve-controlled closed lead-acid battery (VRLA) charging when the internal gas recombination itself is an exothermal reaction, so that the battery temperature rises, floating charge flow increases, the gas evolution increases, and the battery temperature rises higher, the battery itself is a "poor liquid", tightly assemb...
