Electrochemical cell battery system and associated methods of operation are provided based on the incorporation of a thermal suppression construct including a supply of cooling fluid dispensed in intimate contact with the cells disposed within an enveloping sealed enclosure. The electrochemical cells are connected electrically by bus bars to form a battery of cells. The bus bars support cooling by convection methods. The cells are allowed to float mechanically as they are charged and discharged while maintaining intimate thermal contact with the enveloping sealed enclosure through conduction and the bus bars through conduction. The system provides a method of cooling the cells by conduction and convection and that accommodates mechanical changes to both the cells and the enveloping sealed enclosure.

A battery assembly for an electric vehicle includes two spaced-apart longitudinal profiles extending in a length direction L, interconnected to a front and a rear transverse beam. At least three beam shaped battery modules are interconnected along their longitudinal sides via a plate-shaped interconnecting member, and extend in the length direction, to be attached to an inner surface of the front transverse beam via a bracket. Each battery module is provided with cooling channels extending in the length direction L and having an inlet situated between a transverse end face of the module and the inner surface of the front transverse beam. A water inlet duct extends from an external side the front transverse beam in a central area situated between the brackets, for connecting to a coolant inlet of the central battery module.

A battery pack includes: battery cells each including first and second end portions that are opposite each other in a length direction; a case providing an accommodation space in which each battery cell and a cooling fluid for cooling the battery cell are located, the case including a first cover covering the first end portion of the battery cell, the first cover including a first terminal hole through which the first end portion of the battery cell is partially exposed; and first and second sealing members doubly surrounding the first terminal hole from an outside of the first terminal hole to block a cooling fluid leakage passage formed through the first terminal hole. Therefore, while improving heat-dissipating performance, a cooling fluid sealing structure may be provided to the battery pack to prevent cooling fluid leakage from the accommodation space in which the battery cells are accommodated.
