摘要： 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.

摘要： [Problem] To provide a current sensor that can reduce an installation area and improve measurement accuracy.
[Solution] This current sensor comprises: a busbar 2 through which current to be measured flows; and a magnetic sensor 102 that detects a magnetic field component generated by the current flowing through the busbar 2. The busbar 2 is provided with left and right through-holes 2h1, 2h2 which can change the flow of the current to be measured. The magnetic sensor 102 is mounted on the upper surface 2a of the busbar 2. In that case, the magnetic sensor 102 is screw-fixed to the upper surface 2a of the busbar 2 using the left and right through-holes 2h1, 2h2.
