A method and arrangement for providing a compact battery with autonomous cooling

摘要

A motor vehicle having a compact battery and a cooling system therefore is disclosed. The battery 440 includes a plurality of elongate battery cells 412, each battery cell having a longitudinal axis and a hexagonal cross-sectional shape in a plane oriented substantially perpendicular to the longitudinal axis. The cells 412 are arranged in a honeycomb configuration with opposed faces of adjacent battery cells 412 proximately located one to the other in face-to-face relationship. One or more hexagonally shaped cooling channels 442 is provided at an interior location within the plurality of battery cells 412 each of the channels containing a heat transfer fluid 445. A radiating cap 443 is provided to transfer heat from the heat transfer fluid 445 to an air circulation system.
