ams (SIX: AMS), a leading worldwide designer and manufacturer of high-performance analog ICs for consumer, communications, industry, medical and automotive applications, today announced it has developed a reference design which shows how a simple current and voltage measurement circuit can produce state of charge (SOC) readings for electric scooter batteries.
The reference design uses the AS8510 sensor interface from ams, a two-channel battery sensor interface, together with a simple 8-bit microcontroller, an LDO and an LED driver (driving an LED bargraph display). The bill-of-materials cost for these active components is around € 3 / $ 3.70.
