Patent number: 8258726Abstract: A system for cooling a battery mounted on a vehicle using air within a vehicle, independently of the travelling state of the vehicle. The air within a vehicle compartment is guided to a battery mounted on a vehicle to cool the battery. A controller determines a basic fan speed v of the cooling fan based on a battery temperature and an ambient temperature. Further, the controller calculates an increment ?v of the fan speed in accordance with the vehicle speed and the degree of window opening and determines a final fan speed V according to V=v+?v, to drive the cooling fan. By controlling the fan speed to increase, it is possible to cool the battery even when the base pressure of the inlet-side static pressure of the cooling fan becomes negative pressure compared to when the windows are closed.Type: GrantFiled: February 4, 2010Date of Patent: September 4, 2012Assignee: Panasonic EV Energy Co., Ltd.Inventors: Jun Okuda, Toshiaki Nakanishi, Norihito Yuno

Publication number: 20110211312Abstract: A blower includes a fan, an inlet through which air is drawn into the fan, and an outlet through which an air flow from the fan is exhausted. The inlet and the outlet have slits with a specific width or an array of through holes with a specific diameter. The relationship A<C, A<B is satisfied, where A represents the width of the slits or the diameter of the through holes of the inlet, B represents a particle size of dust that is allowed to pass through in view of the dust-proof performance of the fan, and C represents the width of the slits or the diameter of the through holes of the outlet. The blowing performance can be improved within the range of dust-proof performance in which damage or functional degradation can be avoided.Type: ApplicationFiled: December 20, 2010Publication date: September 1, 2011Applicant: PANASONIC CORPORATIONInventors: Toshiya SENOH, Jun SATO
