  • Charger automatically tracking an optimal charging frequency for sinusoidal wave batteries
    Patent number: 8829859
    Abstract: A device and a method automatically trace and fix a resonance frequency of the batteries for offering an optimal charging frequency to the batteries. The device and method utilize a resonance frequency fr that charges batteries with a sinusoidal wave, automatic tracing function, and a fixed current. While the resonance frequency fr is adopted in a charging device and served as the optimum charging frequency, the using life of the batteries could be extended.
