With a recently developed reference design, ams allows designers to readily use simple current and voltage measurement circuitry to produce state-of-charge (SOC) readings for electric scooter batteries. Instead of a voltmeter that tells little about battery life, electric scooter manufacturers can now offer customers a fuel gauge at a nearly comparable cost.
The reference design uses the AS8510 sensor interface, a two-channel battery sensor interface, together with a simple 8-bit microcontroller, an LDO voltage regulator and an LED driver (driving an LED bar-graph display). The bill-of-materials cost for these active components is around $3.70.
