Rise in the round, China's electric car industry started in 2008 by the end of 2015, all kinds of hybrid (HEV) and electric (EV) of new energy automobile production has reached more than 340000, more than 1% of the total output of the domestic automobile sales. Eight years of the new energy car ownership has close to 400000.
So, when China's new energy vehicles has 1 million cars, automotive fuse total supplies will reach more than 400, ten thousand. And the insurance function of automotive fuse and quality security becomes increasingly important.
First of all, the electric car is mainly composed of electric drive system, power system and auxiliary system of three parts, the electric system in the main circuitpower supply system need to install large current fuse to protect, short circuit occurs in a timely manner to ensure that the main road to cut off the power supply to avoid damage to the battery and prevent the line overheat lead to accidents such as fire.
Only to be familiar with the following several operating conditions, you will know how to correct selection
1. The system maximum voltage value
2. The effective value of current main loop
3. The overload current and overload of frequency and time
4. The fault after the circuit time constant of the L/R
5. The expected failure short-circuit current size
According to the current specifications of fuse used electric car industry, electric melting RS308, RS309 series fuse with small size, easy installation, breaking fast, strong resistance to overload capacity, high security features and five major advantages.
