Document Type and Number:
Japanese Patent JP3891860
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a collective battery and a battery system wherein it is possible to suppress reduction of cooling efficiency.
SOLUTION: The collective battery is provided with a battery assembly 11 composed of a plurality of battery cells or battery modules 22, a plurality of restraining members 8a, 8b to restrain a plurality of battery cells or battery modules 22, and coolant supply means 25, 24 to supply a coolant to the battery assembly 11 for cooling the battery assembly 11. Protrusions 21a to 21e are formed on the surface wherein the cooling material flows on the surface of the battery modules 22, and a plurality of restraining members 8a, 8b are arranged so as to be overlapped with the protrusions 21a to 21e in a direction 14 along which the coolant flows in the vicinity of the protrusions 21a to 21e.
