Abstract

The invention discloses a power battery system and a tray thereof. The tray comprises a tray main body used for mounting a power battery module, and a tray framework which surrounds and is connected with the tray main body; the tray framework is used for being connected with an automobile; the tray main body has an inner cavity used for accommodating a coolant; a first channel is formed in the tray framework; and one end of the first channel is connected with the inner cavity while the other end is used for being connected with a finished automobile cooling system. The coolant can circulate in the finished automobile cooling system and the inner cavity of the tray main body so as to cool the power battery module, so that an additional cooling system is not required to be designed, and the size and the weight of the overall power battery system are reduced consequently.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a power battery system and its tray. Background technique [0002] The power battery tray is a part of the power battery system, and generally includes a tray body and a tray frame surrounding the tray body. [0003] In order to meet the cooling requirements of the power battery, the power battery system generally includes a cooling system, so the entire power battery system is relatively large in size and weight. [0004] Moreover, in the existing power battery tray, the traditional welding process is adopted between the tray frame and the tray main body, which is insufficient in manufacturability. In addition, the pallet frame is generally a steel structure, and the main body of the pallet generally adopts a single aluminum alloy casting structure or a composite material structure, which is relatively heavy. Contents of the invention [0005] The problem to be solved by the inven...
