Battery replacement station and battery replacement method

Abstract

The invention belongs to the technical field of electric vehicles, and discloses a battery replacement station and a battery replacement method. The battery replacement station comprises a battery compartment, a positioning device and a locking and unlocking device, wherein the battery compartment comprises a storage rack for storing batteries; the positioning device is configured to position a vehicle parked on the positioning device to a preset position and then lift the vehicle; the locking and unlocking device can move back and forth between the battery compartment and the positioning device and can exchange batteries with the battery compartment so as to replace the batteries for the vehicle lifted by the positioning device; the battery compartment comprises a temporary storage devicefor exchanging batteries with the locking and unlocking device, and the temporary storage device is configured to temporarily storing a power-lack battery after receiving the power-lack battery takenout from the vehicle by the locking and unlocking device, and provide a fully-charged battery for the locking and unlocking device. According to the battery replacement station provided by the invention, the temporary storage device can receive the fully-charged battery in advance after temporarily storing the received power-lack battery, and the fully-charged battery is given to the locking andunlocking device, so that quick completion of battery replacement operation is facilitated, the waiting time of customers is shortened, and the battery replacement efficiency and the user experience are improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery replacement station and a battery replacement method. Background technique [0002] It generally takes several hours to charge the power battery of an electric vehicle, that is, the electric vehicle cannot be used during this period. In order to solve this problem, many electric vehicle manufacturers have developed vehicles that can replace the power battery. Among them, the chassis of the vehicle is equipped with a detachable power battery. Important distribution facilities used. [0003] The process of replacing the battery of the vehicle in the existing power station is roughly as follows: [0004] After the vehicle is positioned by the positioning mechanism, the car is lifted by using the car chassis as the lifting position through the lifting mechanism, and then the depleted battery on the vehicle is removed through the unlocking mechanism and sent to t...

AI Technical Summary

Problems solved by technology

[0005] In view of the above battery replacement method, the lifting mechanism uses the chassis of the car as the lifting part, which means that the battery replacement method is only suitable for vehicles with good skeleton strength, and during the battery replacement process, the lifting mechanism directly contacts the chassis, which will inevitably cause damage to the chassis , and the lifting process will inevitably cause the body that has been positioned to shift again, making the positioning invalid and making it impossible to perform battery replacement operations

[0006] At the same time, in the above-mentioned battery replacement method, the storage of the depleted battery and the access of the fully charged battery need to be carried out in sequence, which prolongs the waiting time for battery replacement, and the customer's physical examination is not good
