Application areas

▼

Battery pack protection

In the battery pack of new energy vehicles, New Energy Electric Vehicle Fuse is used to protect the single cells, battery modules and the entire battery pack in the battery pack. Its high withstand voltage performance and rapid breaking capability can quickly cut off the circuit when a short circuit or overcurrent occurs in the battery pack, preventing the battery from overheating, fire or explosion. This protection mechanism is particularly important for high-energy-density battery systems, especially in the context of increasing battery pack capacity and single cell capacity.

Power Distribution Unit (PDU)

PDU is a key component for battery pack connection and power distribution in new energy vehicles. Fusible Link is installed in the PDU and can effectively protect electronic circuits and control circuits from problems such as excessive current, overheating or short circuit. As the requirements for battery energy density and system reliability of new energy vehicles continue to increase, the fuse contact caps in PDU need to have higher reliability and anti-interference capabilities.

High voltage main circuit protection

The high-voltage main circuit of new energy vehicles is the core circuit of the vehicle drive and is responsible for high-current charge and discharge of the battery and over-current protection of the vehicle drive circuit. Electric Vehicle Fuse prevents high-voltage current from damaging key components such as motors and controllers by quickly cutting off the circuit. In the context of the gradual popularization of 800V high-voltage fast charging technology, the voltage resistance and breaking capabilities of the fuse contact cap are particularly important.

Production Technology and Application of Fuse Contact Cap

Features

High insulation

New energy Fuse uses materials with excellent insulation properties such as high-frequency porcelain or alumina porcelain, which can effectively prevent leakage and short circuits and ensure the safety of the electrical system. At the same time, its insulation performance remains stable under extreme conditions, providing reliable protection for the vehicle's high-voltage electrical system.

Resistant to shock and vibration

The outer cap of EV Fuse is made of high-quality brass tape, which has good plasticity and high strength. It has good machinability, is easy to weld, and is very stable against general corrosion. The contact knife is made of high-purity copper tape, which has a fine structure and extremely low oxygen content. It can withstand strong impact and vibration, ensuring stability under complex working conditions.

Low power consumption

Electric Vehicle Fuse focuses on low power consumption in its design. Its power consumption is extremely low and will not have a significant impact on the vehicle's energy consumption. This low power consumption feature helps improve the vehicle's overall energy efficiency and extend its driving range.

Quick breaking ability

New Energy Electric Vehicle Fuse can cut off the circuit in a very short time, with a time constant of less than 10ms. This rapid breaking capability can effectively protect circuits from overcurrent damage and ensure the safety of vehicle electrical systems.
