In a specific embodiment, the power supply assembly provided by the present invention comprises a battery and a charging device 11 for powering the battery. The battery is disposed in the electric car 3 and is electrically connected to the main circuit of the electric car 3, where The battery includes a main battery 31 and a sub-battery 32 connected in parallel with the positive and negative poles of the main battery 31. The main battery 31 is detachably disposed in the electric car 3. The charging device 11 is disposed in a centralized charging area of a parking lot. 1; The charging device 11 charges the main battery 31, the sub battery 32 drives the electric car 3 to leave the centralized charging zone 1 and enters the parking space 2, and drives the electric car 3 to leave the parking space 2 and enters The centralized charging zone 1 . The above-mentioned power supply assembly includes two parts, namely an on-board part and a fixed part, wherein the on-board part is a battery, the battery includes a main battery 31 and a sub battery 32, and the main battery 31 is detachably installed inside the electric car 3, and the auxiliary battery 32 and The electric car 3 is fixed, the main battery 31 and the sub-battery 32 are connected in parallel, and the rated voltages of the two batteries are equal, the fixed part is the charging device 11, a centralized charging zone 1 is provided in the parking lot, and the charging device 11 is set in the centralized charging zone 1 The charging device 11 is electrically connected to the commercial power.
When the electric car 3 is driven to the parking lot, the electric car 3 first travels to the centralized charging zone 1, and the main battery 31 is separated from the electric car 3 in the centralized charging zone 1 and placed in the centralized charging zone 1 for charging, and the electric car 3 is in the secondary. When the battery 32 is driven to the fixed parking space 2, when the electric car 3 needs to go out, the driver drives the electric car 3 to exit from the parking space 2 to the centralized charging area 1, and the charged main battery 31 is installed to the electric car 3. Internally, the electric car 3 exits the parking lot. During the entire process, the main battery 31 is removed and placed in the centralized charging zone 1 for charging. The power for driving the electric car 3 is from the sub-battery 32. The sub-battery 32 has a small capacity and can only be operated in a short distance. That is, the battery life of the sub-battery 32 is limited to driving in the parking lot. When the electric car 3 needs to leave the parking lot, the electric car 3 is driven by the sub-battery 32 to the centralized charging area 1, and the main battery 31 is installed. In the electric car 3, the main battery 31 provides a power source for the electric car 3 to run, and the electric car 3 drives out of the parking lot. During the running, since the main battery 31 and the sub battery 32 are connected in parallel and the rated voltage is equal, the main battery 31 is constantly The secondary battery 32 is charged so that the secondary battery 32 is supplemented with electrical energy.
Due to the centralized charging of the main battery 31 in the parking lot, the above structure reduces the site input cost, effectively reduces the site input costs, and at the same time concentrates the battery charging. In the centralized charging area 1, one or a smaller number of charging piles can be constructed. To meet the demand, there is no need to construct a charging pile separately for each parking space 2, thereby reducing the investment cost. Since centralized charging is adopted, the centralized charging area 1 collects the main battery 31 that needs to be charged and avoids the parking space 2. The separate installation of the charging pile causes the equipment to be idle (some electric cars 3 do not need to be recharged), so that the equipment utilization rate is high, and the overall charging costs are low, so the user's charging cost is low, and the whole process is more convenient.
