SMART BATTERY, ELECTRIC ENERGY ALLOCATION BUS SYSTEM, BATTERY CHARGING AND DISCHARGING METHOD, AND ELECTRIC ENERGY ALLOCATION METHOD

摘要

The present invention discloses a smart battery, an electric energy allocation bus system, a battery charging and discharging method and an electric energy allocation method. The smart battery internally comprises a battery body portion and a control unit. The smart battery can collect various data of the battery, such as voltage, current, internal resistance, temperature and the like, can be communicated with other smart batteries in a battery pack of a same group and a battery pack control system, and can realize electric quantity transfer among smart batteries of the same group through the electric quantity allocation bus, and realize electric quantity transfer among some batteries of a battery pack accessed to the electric energy allocation bus a power generation device and an electrical load and realize controllable processes of charging and discharging, i.e., active and balanced charging and discharging by using a charging method capable of dynamically adjusting charging parameters during charging and a discharging method for realizing electric quantity transfer among various batteries of the battery pack during discharging.
