<p>PROBLEM TO BE SOLVED: To simplify wiring for heating batteries and to stably dispose each battery in a predetermined method by forming a plurality of concaves, imbedding the batteries in the respective concaves and providing a conductive plane heating element which generates heat with current carried in it so that it may heat each battery. SOLUTION: A plane heating element 10 is formed by providing a plurality of concaves 12 arranged by a lattice partition, and batteries 13 for a motive power of an electric automobile are imbedded in the respective concaves 12. These batteries 13 for a motive power are accommodated in a case 15 made of a reinforced plastic through a hard foaming heat insulator 14, and the case 15 is loaded at mountable and removable in a car body of the electric automobile from below. Further, in the case where the batteries 13 for a motive power are unsuitable for charging because of its low temperature, the batteries 13 for a motive power are so heated as to be charged by applying voltage to a space between a plurality of conductive resin films constituting the plane heating element 10 by an external power source 30 and making resistances between the conductive resin films generate heat.</p> |
