Accurate fuel gauging is essential for any battery‑powered device, giving users clear and reliable insight into how much energy is left and helping avoid unexpected shutdowns.
Nordic’s fuel gauging provides accurate state of charge information for all supported battery types. Battery state of health is also supported for rechargeable batteries - tracking actual capacity and aging over time to understand how the battery performs throughout its lifetime. This deeper insight helps devices stay reliable for longer and makes rechargeable battery replacement more predictable.
By combining high accuracy with ultra‑low power operation - including zero power consumption in sleep - and low system cost, the Nordic algorithm-based fuel gauge solution delivers accurate battery information without extra components, licensing fees, or impact on battery life.
