Title:
Mobile battery
Document Type and Number:
Japanese Patent JP6139303
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a mobile battery capable of enhancing the safety property by physically separating a printed board having a power supply circuit for an AC power supply from a secondary battery, in a small case.SOLUTION: A mobile battery 10 has: a case 3; a built-in secondary battery 6; an insertion plug 5; a commercial AC voltage input circuit; an AC-DC voltage conversion circuit; a charge control circuit; and a discharge control circuit. The mobile battery 10 has the built-in secondary battery 6 in the case 3, and has on one surface a fire-retardant circuit board 4 at least having main components of the commercial AC voltage input circuit and main components of the AC-DC voltage conversion circuit. At least a part of a space in the case 3 is partitioned by the circuit board 4, and the built-in secondary battery 6 is arranged away from the circuit board 4 in a space at the other surface side of the circuit board 4, of the space in the case 3 partitioned by the circuit board 4.
