<p><P>PROBLEM TO BE SOLVED: To provide a battery unit capable of improving heat dissipation efficiency. <P>SOLUTION: The battery unit includes: a case; a circuit board provided in the case; a battery cell provided in the case and causing an endothermic reaction during charging and an exothermic reaction during discharging; a heat generating component provided on the circuit board; and a heat transferring member thermally connected with the heat generating component and the battery cell to transfer heat generated by the heat generating component to the battery cell. By the battery unit, efficient heat dissipation can be carried out by heat absorption due to a chemical reaction occurring during charging of the battery cell and heat dissipation using the heat transferring member and a heat dissipation member. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
