Battery pack
First Claim
1. A battery pack, using a battery comprising one or more cells as a power source and for connecting power to an external host device, said battery pack comprising:
- charging/discharging means connected in series to said battery and used for discharging and discharging;
current detecting means for detecting the charging/discharging current;
voltage detecting means for detecting voltage; and
temperature detecting means for detecting temperature, whereby;
at least charging state, discharging state, charging stop state and discharging stop state can be selected by controlling said charging/discharging means based on the charging/discharging current, the voltage, and the temperature as detected, and it is turned from one of these states to another state, and state transition information is transmitted to the external host device.

Abstract
The present invention provides a battery pack, using a battery 1 comprising one or more cells as a power source and for connecting power to an external host device, and it comprises charging/discharging means 2-4 connected in series to the battery 1 and for performing charging and discharging, current detecting means 6 and 7 for detecting charging and discharging current, voltage detecting means 5 for detecting voltage, temperature detecting means for detecting temperature, and control means 9, whereby the control means is operated in such manner that it turns the state from at least one of charging state, discharging state, charging stop state, and discharging stop state to another state by controlling the charging/discharging means 2-4 based on the charging/discharging current, the voltage and the temperature as detected, and said state information is transmitted to the external host device when there is a request or at regular interval or when there is state transition, and state transition such as a charging/discharging state or a stop state of the battery pack controlled according to charging/discharging current, voltage, and temperature is controlled, and information of state transition can be managed and controlled by the external host device.
