  • Patent number: 11887796
    Abstract: Relays having internal connections on both sides of their switches may be used in conjunction with a connector that integrates both the normal relay switch control lines with the sensing conductors of a control module for a battery module of an energy storage device. In this manner, sensing conductors may be routed along with the switch control lines for the relay instead of separately as described above. This integration reduces the complexity and cost associated with the energy storage device, because it reduces the number of separately routed lines and also eliminates the external connections for at least some of the sensing conductors.
