Abstract:
A method for providing battery diagnostics includes: measuring a first voltage across a first battery cell of a rechargeable battery via a first measurement path of a network using a first measurement circuit, measuring the first voltage including taking at least one first voltage sample during a first time period using the first measurement circuit; measuring a second voltage across the first battery cell via a second measurement path of the network using a second measurement circuit, measuring the second voltage including taking at least one second voltage sample during the first time period using the second measurement circuit, where the second measurement path of the network is different from the first measurement path of the network; comparing the measured first voltage with the measured second voltage; and generating a diagnostic output signal based on the comparison.
