Battery Monitoring System Including Relay Test Circuit

摘要

A battery monitoring system includes a central monitoring system and a set of individual battery selectors. The central monitoring system is electrically connected to the battery selectors and each of the battery selectors is connected to one or more batteries. In operation, commands are sent from the central monitoring system to the individual battery selectors so as to turn one on at a time. When the battery selector is on, test and response signals can be communicated between the one or more batteries connected to the battery selector and the central monitoring system. In some embodiments, the system includes a relay test circuit.

主权项

1. A central monitoring system comprising:
interrogation signal logic configured to generate interrogation signals, the interrogation signals being configured for detecting a state of a battery; sensing logic configured to receive sense signals from the battery and to interpret the received sense signals to generate data characterizing the state of the battery; selection logic configured to generate selection signals, the selection signals being configured to select the battery from among a plurality of batteries; a bus interface configured to communicate at least the interrogation logic to a signal bus and to receive the sense signals from the signal bus, and including a test circuit configured to test a state of a relay connected to the signal bus; and a microprocessor configured to execute at least the sensing logic.
