Abstract
Systems and methods are provided for controlling battery temperature, for example those used in electric vehicles.
Claims19
A system for controlling temperature within a battery pack, comprising:
- a battery pack comprising at least one electrochemically rechargeable battery cell;
- a source of temperature control gas;
- and
- a temperature control gas distribution and heat transfer system comprising:
- at least one gas delivery section delivering temperature control gas to the battery pack, and
- downstream from the gas delivery section, at least one heat exchange section substantially parallel to a surface of the battery pack and having a direction of flow, wherein the heat exchange section passes only across a portion of the pack that is shorter than the dimension of the pack as measured in a direction substantially parallel to the direction of flow of the heat exchange section.
3 more elements
A system for controlling temperature within a battery pack, comprising:
- a battery pack comprising at least one electrochemically rechargeable battery cell;
- a source of temperature control gas;
- and
- a temperature control gas distribution and heat transfer system constructed and arranged such that at least a portion of the temperature control gas is not transported from one boundary of the battery pack to an opposed boundary of the battery pack.
1 more element
A system for controlling temperature within a battery pack, comprising:
- a battery pack comprising electrochemically rechargeable battery cells;
- a source of temperature control gas;
- and
- a temperature control gas distribution and heat transfer system comprising a flow path comprising:
- a first portion that is directed at a first boundary portion of the battery pack and is deflected proximate the first boundary portion such that the flow path changes direction, the battery pack lying within the reflex angle defined by the direction of the flow path, and
- a second portion that is deflected proximate a second boundary portion of the battery pack such that the flow path changes direction and enters the battery pack through the second boundary portion.
3 more elements
A system for controlling a temperature within a battery pack, comprising:
- a battery pack comprising electrochemically rechargeable battery cells;
- a source of temperature control gas;
- and
- a temperature control gas distribution and heat transfer system comprising a flow path comprising:
- a first portion that is deflected proximate a boundary of the battery pack such that the flow path changes direction and enters the volume of the battery pack through the boundary, and
- a second portion that is deflected within the battery pack such that the flow path changes direction.
3 more elements
A method of controlling temperature within a battery pack, comprising:
- establishing the flow of a temperature control gas across at least a portion of a surface of a battery pack, wherein at least a portion of the temperature control gas is not transported from one boundary of the battery pack to an opposed boundary of the battery pack.
