Lithium battery is categorized as non-ideal power source even if it merits in mass/size power densities. Generally speaking, the recharging facilitation and the cruising scope of the humanoid robot are conspicuously restrained by the heavy weight and the state of discharge (SOD) instability. Traditionally, sensor-based recharging stations are inevitably time-consuming and inconvenient whenever the localization is taken into consideration. This paper is aimed to organize an inventive, inexpensive, convenient, and reliable inductance recharging system (IRS) with pseudo-series connected circuit to facilitate cell-recharging, stabilize Lithium cells, and protect the battery system on the humanoid robot. Finally, computer simulations and recharging experiments are carefully examined and demonstrated the advantages of the proposed algorithm.
