  • Publication number: 20230170545
    Abstract: In a battery pack for use in an electric vehicle at least two longitudinal rows of prismatic battery cells extend side-by side in the length direction (L). The cells are packed in an array including transverse rows. The array has longitudinal sides. Plate-shaped cooling members are interposed between adjacent cells in the longitudinal rows and extend in the width direction (W) from an upstream longitudinal side to the opposite longitudinal side of the array. Each plate-shaped cooling member is connected with an inlet to a coolant distribution duct and with an outlet to a coolant outflow duct. The distribution duct and the outflow duct extend parallel to sill members. The distribution duct is connected to a supply duct and the outflow duct is connected to a return duct, the supply duct and the return duct extending through the front piece and/or the transverse member.
