Abstract
The present disclosure generally pertains to testing of secondary batteries. More specifically, the disclosure relates to a movable walk-in chamber for testing secondary cells. According to a first aspect, the present disclosure relates to a movable walk-in chamber for testing secondary cells comprising an enclosure, racking, a plurality of cycler interfaces and cabling. The enclosure form at least one thermally isolated temperature chamber. Furthermore, the enclosure comprises a walking aisle arranged between an entrance and an exit. The racking is arranged at inner walls of the enclosure along the walking aisle. Secondary cells can be inserted in the racking for testing and removed after testing. The plurality of cycler interfaces are arranged at outer walls of the enclosure. Each cycler interface comprises a power interface and one or more cell interfaces. The cabling is arranged to connect the power interfaces to at least one central power connector, whereby cyclers connected to the cycler interfaces can be powered from the movable walk-in chamber. The cabling is also arranged to connect the cell interfaces to poles of secondary cells inserted in the racking, whereby cyclers connected to the cycler interfaces are able to perform testing on cells arranged in the racking.
