Battery cabin

The invention relates to a battery cabin. The battery cabin comprises a cabin body for accommodating corresponding batteries, wherein anode contacts and cathode contacts for being electrically connected with the anodes and the cathodes of the batteries are fixedly arranged on the cabin body or connected to the cabin body through leads; the anode contacts have anode contact splicing ends; and the cathode contacts have cathode contact splicing ends. The batteries in each battery pack are placed into different battery cabins respectively; the anode contacts are electrically connected with the anodes of the batteries; the cathode contacts are electrically connected with the cathodes of the batteries; and each battery cabin constructs one module. When a power supply needs to be assembled, the anode contact splicing ends and the cathode contact splicing ends are electrically connected with adaptive contacts on other battery cabins in a plug-in way respectively, so that connection among battery packs can be realized, and the battery packs can be connected conveniently and rapidly. Moreover, a welding process is not needed, so that the quantity of the battery cabins needing to be connected can be selected as required on site, and the power supply is more diversified.
