1. A system for determining float current in a battery system having a plurality of battery cells connected in series with each other, comprising:

  • a voltage sense circuit operable to measure a voltage drop across an electrical connection between two of the battery cells;

    a test load circuit that operates to apply a load across the electrical connection and at least one of the two battery cells and measure current flow through the electrical connection; and

    a controller configured to receive current measures from the test load circuit and determine a resistance of the electrical connection based on the current measures, the controller further configured to dwell on obtaining voltage drop measures from the voltage sense circuit taken only when a load is not being applied across the electrical connection and compute a float current flowing through the electrical connection from the resistance of the electrical connection and the voltage drop measures.
