B-Power let the starting(DCR) and voltage-stabilized(ACR) capability of itself be disconnected with the battery size. The roles of super capacitor and battery are independent. This is why it is also called hybrid battery. The patent of the B-Power has been granted in Taiwan (I750087)。

   The super capacitor can discharge very big current instantly, and this discharged current can be made use of starting engine. In addition, the designed low ACR of the super capacitor can offer better voltage-stabilized capability than the traditional lead battery. Besides, even though battery is paralleled with the super capacitor, there is the charging control IC between them. Thus, the battery will not participate the engine starting process, and can be protected behind. The battery is only charged and discharged at constant currents. Therefore, the battery pack can maintain its life as long as that of the single battery.
