PROTECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/137452
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a protection system capable of suppressing, using a pyro-switch, energy generated when cutting battery wiring. The protection system has: a shunt resistor 100 for measuring the value of current flowing from a battery B to a motor M; a pyro-switch 200 for cutting a shunt resistor 100 on the basis of a predetermined signal; and a suppression unit 2 connected between the shunt resistor 100 and the motor M. The suppression unit 2 suppresses the energy generated by cutting the shunt resistor 100 by the pyro-switch 200.
