Battery Pack
First Claim
1. A battery pack comprising:
- a plurality of prismatic rechargeable batteries, each of which is formed by accommodating an electrode assembly and a liquid electrolyte in a battery case and sealing an open end of the case with a sealing plate, an electrode terminal being provided in the sealing plate;
a circuit substrate formed with a battery management circuit for managing the operating state of each rechargeable battery; and
a pack case for accommodating the rechargeable batteries and the circuit substrates, wherein;
the plurality of rechargeable batteries are held by a frame in such an arrangement that the batteries are oriented in the same direction on their sealing-plate side, whereby the plurality of rechargeable batteries are integrated;
the circuit substrate is mounted to a frame for holding the sealing-plate side of the plurality of rechargeable batteries; and
a resin mold is provided for covering a necessary surface of the circuit substrate with a resin after the circuit substrate is electrically connected to the rechargeable batteries and to input and output terminals.

Abstract
A battery pack is provided, in which a plurality of rechargeable batteries are held by a center frame, a bottom-side frame, and a terminal-side frame in a parallel spaced relationship, the plurality of rechargeable batteries being connected in series and integrated with a circuit substrate by mounting the circuit substrate on the terminal-side frame, the circuit substrate being provided with a resin mold, whereby the battery pack is free of damage to electrical circuit parts even in the event of entrance of water or dust through vents that are provided for suppressing temperature rise of the rechargeable batteries. The plurality of rechargeable batteries are connected in series by joining connection plates to the positive and negative electrode terminals formed on the sealing plates of plurality of the rechargeable batteries that are held by the terminal-side frame, and connection projections formed to each connection plate are fitted in respective connection holes in the circuit substrate so as to integrate the circuit substrate with the rechargeable batteries, whereby the wiring for connecting each of the rechargeable batteries to the circuit substrate is made simple.
