A heat insulation sheet () covers a temperature fuse () arranged on a sealing plate () of a rechargeable battery () so as to provide a shield from heat of resin that is filled in a gap between the rechargeable battery () and a circuit substrate () to form a primary mold () and to prevent destruction of the temperature fuse () caused by the heat.

Method for manufacturing battery pack

A rechargeable battery () and a circuit substrate () are connected by lead plates () and united by a primary mold () that is formed by filling resin therebetween, after which a secondary mold () is formed on the outer face by filling resin at necessary locations and a winding sheet () is wound around the periphery, thereby forming a battery pack.

Method for manufacturing a battery pack

A circuit substrate () being electrically connected to a rechargeable battery () is arranged upon a sealing plate () with a gap therebetween and united with the rechargeable battery () by filling resin in the gap. A primary mold () formed by the resin is firmly retained by undercut portions formed in engaging protrusions (). The engaging protrusions () may be formed by welding separate engaging members ().

Battery and method of manufacturing the battery

Battery pack having circuit substrate resin molded to battery

Constructing a battery pack by: providing a resin sheet () to cover a release opening () of a safety vent () formed on a sealing plate (); integrating a rechargeable battery () and a circuit substrate () with a primary molding () by filing a resin between the rechargeable battery () and the circuit substrate (); and then forming a secondary molding (). In such constructed battery pack, an ejected gas, at the operation of the safety vent () of the battery pack, is externally released through an interface between the resin and metal.

A portable personal computer ( ) makes access to a service handling server ( ) set up on the Internet ( ), and transmits data from a power source monitor ( ). The service handling server ( ) identifies a model type of the personal computer ( ), refers the received data to a power source information database ( ), determines whether good or bad, transmits a reply notifying a determination result when there is no abnormality, and transmits abnormality action information using an e-mail when there is an abnormality.
