This invention relates to the field of battery box technology, and proposes a fire-fighting experimental platform and system for charging stations with a liftable and replaceable experimental battery box. The system includes a top frame and a lifting base that drives the top frame to move up and down. The top frame is equipped with a clamping platform for receiving the replaced battery box. The clamping platform is equipped with a clamping device to control the clamping distance and an electric roller assembly to deliver the battery box out of the clamping platform. Below the top frame is a battery box replacement platform for placing the battery box to be installed. The replacement platform is elastically supported on the lifting base by elastic guides. Two sets of lifting components are provided on both sides of the replacement platform to lift it up when the top frame moves down. When the battery box to be installed on the replacement platform is lifted to the height of the clamping platform, this invention enables the alternating installation of old and new battery boxes, thereby improving replacement efficiency and providing a platform for fire-fighting battery box replacement experiments in charging stations. It also solves the problem of the cumbersome experimental demonstration process in existing technologies.
