Title:
放電制御装置
Document Type and Number:
Japanese Patent JP7061691
Kind Code:
B2
Abstract:
If a wire is broken at a connecting portion 5a, the connection with a positive electrode wiring 4a is broken and a second discharge circuit 11 is lost. However, a first discharge resistor 6 is connected to a positive electrode wiring 4a, and a first discharge circuit 9 is maintained. If a wire is broken at a connecting portion 5b, the connection with a negative electrode wiring 4b is broken and the second discharge circuit 11 is lost. However, the switching element 7 is connected to the negative electrode wiring 4b via a board wiring 3 and a relay wiring 21, and the first discharge circuit 9 is maintained. If a wire is broken at a connecting portion 5c, the connection with the first discharge resistor 6 is broken and the first discharge circuit 9 is lost, but the second discharge circuit 11 is maintained. When a wire is broken at a connecting portion 5d, the connection between the switching element 7 and the second discharge resistor 10 is maintained at the connecting portion 5b, and the first discharge circuit 9 and the second discharge circuit 11 are maintained. According to the invention, a discharge can be maintained even if a disconnection occurs in a connecting portion with a discharge resistor.
