摘要： A battery monitor device is provided for determining float current in a battery system. The battery monitor device is comprised of: a voltage sense circuit electrically coupled to opposing sides of a connector coupling two battery cells and operable to measure a voltage drop across the connector; a test load circuit that operates to apply a load across the least one battery cell and connector and measure current flow through the connector; and a controller configured to receive voltage drop measures from the voltage sense circuit and current measures from the test load circuit. The controller operates to determine a resistance of the connector and computes a float current flowing through the connector from the resistance and voltage drop measures taken only when a load is not being applied across the connector.

摘要： In one aspect the present disclosure relates to a system for measuring an internal resistance of a battery. The system may involve: a processor; a load module responsive to the processor for applying a load across the battery; a current sense subsystem for sensing the current flowing to the load module and generating a sensed current signal in accordance therewith; a multiplexer module in communication with the current sense subsystem for detecting voltages with the load coupled across the battery and uncoupled from the battery, and generating voltage signals in accordance therewith; and a filtering and amplification subsystem responsive to the multiplexer module, for filtering and amplifying a level of each of the voltage signals to produce modified voltage signals for use by the processor in determining the battery internal resistance.
