The nitrogen fire protection system pioneered by Guchen Team can effectively prevent thermal runaway and thermal runaway propagation in lith

EV lithium-ion batteries are increasingly used in electric vehicles and energy storage systems, which are exposed to high temperatures during charging and discharging. In addition, the fire is also a major safety hazard for EV lithium-ion battery safety. Therefore, it is essential to take measures against thermal runaway in order to prevent the occurrence of an accident caused by fire.

During charging and discharging, hot spots may occur on the surface of the battery or inside the battery due to internal short circuits or failures. These hot spots can trigger internal explosions or fires that can cause serious damage to people or property. Therefore, it is necessary to prevent thermal runaway in EV lithium-ion batteries during charging and discharging.

The most commonly used method for preventing thermal runaway in EV lithium-ion batteries has been through the use of metal halide fire extinguishers or water-based fire extinguishers; however, these methods have several shortcomings such as low efficiency, high cost and poor reliability. Therefore, there is a need for more effective methods for preventing thermal runaway in EV lithium-ion batteries.

Nitrogen fire protection system is regarded as the most efficient and reliable thermal runaway risk prevention method in EV lithium-ion battery safety; it can effectively suppress internal explosion caused by heat.

nitrogen protect ev battery from thermal runaway

[guchenconnectors]

The active nitrogen fire protection system is a lithium ion battery fire protection technology that has been successfully demonstrated at several thousands electric vehicles around the world, including those in Yutong electric buses, mining trucks and sightseeing buses.

The active nitrogen fire protection system is an effective and reliable solution for electric vehicles with high voltage lithium batteries. When a battery catches fire or there are other abnormal conditions, the system automatically releases nitrogen to protect the battery from further damage. As a result, it quickly prevents the lithium-ion battery pack from thermal runaway. https://www.guchen-connector.com/blog/industry-blog/the-most-advanced-fire-protection-technology.html

The high voltage wiring harness is a critical component in the operation of an electric vehicle.

HV wire harness assemblies for automotive applications are designed to meet the strict requirements of OEMs /Tier 1 suppliers in terms of pe

The high voltage wiring harness is used to connect the high voltage battery pack to the rest of the vehicle's electrical system. It consists of several components that are designed to handle high voltages and provide reliable performance. The most important part of a high voltage wiring harness is its insulation system. This must be able to withstand the heat generated by the current flow without melting or becoming brittle. The insulation must also provide adequate protection against short circuits, preventing sparks from reaching other components such as electronics and fuel tanks.
