The present invention relates to a tray for housing a plurality of individual battery modules, the tray comprising a bottom wall and side walls defining a receiving space for the plurality of individual battery modules, wherein the tray has one or more inner walls extending between opposite side walls and subdividing the receiving space in a plurality of individual battery module receiving chambers each bounded by a part of the bottom wall and by one or more side walls and/or inner wall or walls, and a coolant inlet and a coolant outlet, wherein at least one of the side walls and/or at least one of the one or more inner walls comprises a plate shaped base part made of a thermoplastic material and comprising a wall-channel for a flow of a coolant medium on at least one plate side of the base part, wherein the wall-channel is in connection with the coolant inlet and with the coolant outlet such that a coolant medium can flow through the wall-channel, and a thermoplastic-based layer bonded to the base part such that it covers and thereby closes off the wall-channel, wherein the wall concerned is oriented in the tray such that it faces one or more of the battery module receiving chambers with a plate side thereof having the layer bonded thereto. The invention also relates to a system including one or more of said trays and a cooling system as well as to a method for cooling a plurality of battery modules.
A tray for housing a plurality of individual battery modules, the tray comprising a bottom wall and side walls defining a receiving space for the plurality of individual battery modules, wherein the tray has one or more inner walls extending between opposite side walls and subdividing the receiving space in a plurality of individual battery module receiving chambers each bounded by a part of the bottom wall and by one or more side walls and/or inner wall or walls, and a coolant inlet and a coolant outlet,
The tray according to any one of the preceding claims, wherein the wall-channel has multiple branches such that the coolant medium flows via the multiple branches in use.
The tray according to any one of the preceding claims, wherein the bottom wall as well comprises a said plate shaped base part made of a thermoplastic material and comprising a bottom-channel for a flow of a coolant medium on at least one plate side of the base part, wherein the bottom-channel is in connection with the coolant inlet and with the coolant outlet such that a coolant medium can flow through the bottom-channel, the bottom wall further comprising a thermal conductive layer, preferably a thermal conductive film, bonded to the base part such that it covers and thereby closes off the bottom-channel, wherein the bottom wall is oriented such that it faces the receiving space with an inner plate side thereof having the layer bonded thereto.
The tray according to any one of the preceding claims, wherein at least 20 percent of a plate surface of each wall part enclosing each of the battery module chambers is free from the wall-channel so as to serve as an abutment for positioning the battery module in the chamber concerned.
The tray according to any one of the preceding claims, wherein inner walls of the tray extending perpendicular to each other subdivide the receiving space in at least four said battery module receiving chambers in a matrix-shape of at least two by at least two battery module receiving chambers,
A system for housing a plurality of individual battery modules, comprising:
