Embodiment 1
[0028] When the present invention utilizes the above-mentioned system to distribute energy, it includes:
[0029] When a charging device charges multiple batteries to be charged at the same time, the charging device establishes real-time communication with the battery pack to be charged of the access device itself. Specifically, the main control MCU of the charging device and the charging MCU of the battery pack component are established through the CAN bus. Communication, charging MCU and battery one-to-one correspondence, the corresponding charging MCU obtains the required power of the corresponding battery, and sends the required power to the main control MCU.
[0030] The main control MCU summarizes the total required power of all communication uploads: the total power required; the maximum output power of the charging device itself: the total output power available; the main control MCU compares the total required power with the total output power, and decides to output th...
Embodiment 2
[0033] In this embodiment, the communication relationship between the main control MCU, the charging MCU and the battery is the same as that in Embodiment 1, and details are not repeated here. The main control MCU compares the required total power with the total output power. If the available total output power is less than the required total power, the n batteries are prioritized according to the required power from small to large, and the charging device charges the batteries according to the priority. .
[0034] Therefore, in this embodiment, it is necessary to classify according to the size of the required power obtained by the charging MCU, and the smaller the required power, the higher the priority for charging. When the charging device charges the battery according to the priority, after the battery at the previous level of the priority is charged, the battery of the next level is charged. For example, when charging 5 batteries at the same time, the required power of t...
Embodiment 3
[0036] In this embodiment, the main control MCU compares the required total power with the total output power, and the charging decision is: if the available total output power is less than the required total power, the charging equipment is divided into n batteries according to the proportion of the required power of the battery Battery. Wherein, the ratio is the ratio of the required power of the n batteries to the required total power, respectively.
[0037] For example, to charge 5 batteries at the same time, mark these 5 batteries as battery A, battery B, battery C, battery D, and battery E. The power required by these 5 batteries is 20%, 30%, 40%, 50%, 60%; then the proportions of these 5 batteries are: 1 / 10, 3 / 20, 1 / 5, 1 / 4, 3 / 10; the total available output power of the charging equipment is distributed according to the above proportions . That is, 1 / 10 of the total output power is allocated to battery A, 3 / 20 of the total output power is allocated to battery B... and ...
