Abstract (en)
[origin: WO2020260482A1] The battery (1) comprises: - a casing (5) which internally delimits a volume (7) for receiving electricity storage cells (3); - a heat exchanger (11) comprising a metal upper plate (13) which defines the bottom of the casing (5), a lower plate (15) which delimits with the upper plate (13) a volume (17) for circulation of a heat transfer fluid, and a plurality of upper fins (19) which are received in the circulation volume (17) and arranged to transmit forces between the upper and lower plates (13, 15); - a protection plate (23) which covers the lower plate (15) and delimits with the lower plate (15) a lower volume (25); - lower rigidification fins (27) which are received in the lower volume (25) and arranged to transmit forces between the protection plate (23) and the lower plate (15), the lower plate (15) forming with the lower fins (27) and the protection plate (23) a rigid frame (28) which takes up the majority of the forces to which the battery (1) is subjected.
