6 FAQs about [Valve mold lithium battery]
Why do lithium-ion batteries need explosion-proof valves?
Designing and installing explosion-proof valves are vital in protecting lithium-ion batteries from harm. By responding quickly in fault or abnormal conditions, explosion-proof valves reduce risks while protecting other components within the battery from failure chain reactions that could otherwise arise from its failures.
How does a battery safety valve work?
A safety valve was installed in the battery to prevent explosions due to excessive internal pressure. A battery tester (brand: NEWARE) overcharged the battery. Thermocouples measured the temperature. A decibel meter (brand: Delixi, model: DSM-D1) analyzed the opening duration of the battery safety valve , .
What is a battery fault detection module (PRV)?
When the battery fault detection module identified that the battery safety valve was open, the PRV was opened immediately to release FEGs inside the LCBP. The novel PRV’s hardware and software components were developed, along with its integration with the BMS to modify the charging and discharging strategy of battery.
Why is the TR behavior of lithium ion batteries inconsistent?
The TR behavior of LIBs is inconsistent due to various factors such as different positive and negative electrode materials , , state of charge , state of health , and causes of battery TR (thermal, electrical, and mechanical abuse) , , as well as the operational environments , .
Can a PRV be opened after a battery safety valve is opened?
Experimental tests have shown that conventional PRV that rely on pressure differentials are difficult to open in time after the battery safety valve is opened. The VE generated during battery TR cannot pass through the PRV membrane. In addition, numerical studies revealed that larger sizes of PRV are better.
What happens when LCBP batteries vent?
When the internal batteries vent due to TR or when an explosion occurs inside the LCBP, the internal pressure rapidly increases, compressing the spring and pushing the piston to open the exhaust channel for pressure relief. The membrane PRV has a waterproof and breathable membrane on the exhaust channel.
