Smart Charger Significantly Increases E-Bike Battery Lifetime

MARYLAND, USA - E-bike battery lifetime is predominantly determined by stress and cell temperature and cell quality. For existing batteries, only stress can be addressed. Stress substantially increases above 80% and below 20% State of Charge (SoC). E-bike batteries are rarely below 20% but are always charged to 100%, even during storage. This reduces the e-bike battery lifetime.
CALCE, a major reliability and lifetime test lab at the university of Maryland, USA performed a year-long test, which proved that charging to 80% doubled cycle lifetime compared to 100%. – Photo Bike Europe
