Abstract
A vehicle battery insulating system includes an inner wall and outer wall forming an insulating cavity filled with a microporous material such as microporous silica. A vacuum pump is coupled to a first connection of the cavity and a valve is coupled to a second connection of the cavity. A controller operates the vacuum pump and the valve to lower/raise pressure within the cavity to decrease/increase thermal conductivity, respectively, of the insulating layer to influence temperature of a vehicle battery. A battery housing may include inlet and outlet ports coupled to a pump to circulate a heat exchanging fluid. The controller may monitor temperatures from sensors and/or receive wireless information relative to traffic, ambient temperature, weather forecasts, and similar information for use in controlling the insulating system in an attempt to keep the vehicle battery within a desired operating temperature range.
