1. A system for determining battery state-of-charge (SoC) in an electric vehicle, comprising:
- an inverter that converts battery power to an alternating current;
a current sensor that generates a signal indicative of a magnitude and direction of the alternating current;
a first analog-to-digital converter (A2D) that converts the signal to current data; and
a central processing unit (CPU) that periodically stores a present value of the current data to an associated memory and determines the SoC based on the stored current data.
