Technical Field

The invention relates to a technology in the field of new energy electric automobiles, in particular to a battery replacement and cleaning system for a battery replacement station.

Background

At present, battery replacement is the fastest electric energy supplement mode of the electric automobile. In order to facilitate replacement, the battery is exposed and installed at the bottom of the vehicle body. And thus sludge, dust, etc. are inevitably accumulated on the bottom and side surfaces of the battery during the running of the vehicle. If not cleaned, dust flies in the battery conveying process, possibly causing charging faults and having larger potential safety hazards.

In addition, potential safety hazards exist when batteries are replaced in bad weather such as rainy days without adding protective measures. Once rainwater dropping from the vehicle body enters the electrical connector 101 of the power battery 100, as shown in fig. 6, the rainwater may cause damage to the battery when being light, and may cause personal safety accidents when being heavy.

the present invention has been made to solve the above-mentioned problems occurring in the prior art.
