Problems solved by technology

[0004] However, since the battery information is in a communication format only between the battery pack and the portable PC, it must be converted into a data format recognizable on the network in the portable PC. If the portable PC is not started, the management computer cannot obtain the battery pack. Information
In addition, in order to obtain information for maintenance and management, it is performed at night in order not to interfere with the work performed by all computers including portable PCs. able to obtain information

Abstract

To make a battery pack (2) capable of connection over a communication network for the sake of maintenance of the battery pack (2). The battery pack (2) is provided with a network interface (12) given a unique IP address, which is connected to a LAN along with a network interface (11) of a PC body (1). Even if the PC body (1) is suspended, the battery pack (2) can be accessed over the LAN. A computer for maintenance, arranged on the LAN, can thus access the battery back (2) to acquire the operating status of a rechargeable battery (3) and data stored in a memory (8), such as a serial number, thereby performing maintenance.

Description

technical field [0001] The present invention relates to a battery pack having a function capable of communicating via a network. Background technique [0002] Portable personal computer (hereinafter referred to as portable PC) is a battery pack used as a power source for carrying. It has a battery remaining capacity display function and a battery protection function. It outputs data such as battery voltage or battery remaining capacity through a communication bus (SM bus, etc.) To the PC body, and the PC body controls the battery pack, thus forming a power management system such as an intelligent battery system. A portable PC equipped with such a battery pack can be connected to a LAN in an enterprise or the like, and required information can be collected or updated by a management computer for maintenance and management. [0003] Since the information of the battery pack is transmitted to the main body of the PC through the aforementioned communication bus, the management ...
