Abstract
A battery connection unit includes a first branch with a first branch switch adapted to connect a first battery to at least one of a second battery and a vehicle load; and a second branch with a second branch switch connected in parallel with the first branch. A first measurement switch is connected between the first branch and a storage element to enable/disable charging. A second measurement switch is connected between the second branch and the storage element. A processor is programmed to: disable at least one of the first branch and the second branch; enable at least one of the first measurement switch and the second measurement switch to charge the storage element with leakage current; and generate an output signal indicative of a switch fault in response to a storage element voltage associated with the leakage current exceeding a reference voltage within a predetermined time period.
