Abstract
A method for determining the charge in a battery which comprises providing a main battery and a auxiliary battery. The method then comprises connecting the main battery to an electrical load; measuring I1, the current drawn from the main battery while it is connected to the electrical load; connecting the auxiliary battery in parallel with the main battery and the electrical load; measuring I2, the current drawn from the main battery while it is connected to the electrical load and the auxiliary battery; and estimating the state of charge in the auxiliary battery based upon at least the difference between I1 and I2.
