US Patent:

20090321532, Dec 31, 2009
Filed:

Jun 27, 2008
Appl. No.:

12/163080
Inventors:

Jerome MAITRE - Royal Oak MI, US
Assignee:

Bayerische Motoren Werke Aktiengesellschaft - Muenchen
International Classification:

B60H 1/32
H01M 10/50
F28D 15/00
US Classification:

236 91 R, 429120, 16510411
Abstract:

A cooling system for a vehicle battery is described. The system has a cooling loop in heat transfer communication with the battery, for removing heat therefrom with a coolant, a first cooling device selectively coupleable to the cooling loop, using a refrigerant fluid to transfer heat with the coolant, and a second cooling device selectively coupleable to the cooling loop, using ambient air to transfer heat with the coolant. Various temperature sensors for sensing an ambient temperature and a battery temperature are provided, and connected to a controller that implements a coolant flow bypass function by commanding operation of a valve to bypass the selected one of the cooling devices in response to the battery and the ambient temperatures.

Filed:

Jul 9, 2008
Appl. No.:

12/170178
Inventors:

Jerome MAITRE - Royal Oak MI, US
Ralph Ostermeier - Munich, DE
Christoph Niedermeier - Munich, DE
Assignee:

Bayerische Motoren Werke Aktiengesellschaft - Muenchen
International Classification:

H01M 10/50
F28D 15/00
US Classification:

429 62, 429120, 16510431, 16510433
Abstract:

A cooling system and method for a vehicle battery is described. A high flow rate cooling loop in heat transfer communication with the battery is provided, for removing heat from the battery with a coolant. A first cooling device may be selectively coupled to the high flow rate cooling loop, using a refrigerant fluid to transfer heat with the coolant, and a second cooling device can also be selectively coupled to the high flow rate cooling loop, using ambient air to transfer heat with the coolant. A valve for directing the coolant to at least a selected one of the first and second cooling devices is provided, and a controller is used to implement a coolant flow bypass function by commanding operation of the valve to bypass the selected one of the cooling devices to limit a temperature gradient between the coolant and the battery.
