Abstract
The apparatus of this invention has a resetting function for software- or hardware-resetting a battery when a CPU in the battery hangs up and becomes inoperable or inoperative to make it possible to recover the CPU of the battery from a hang-up state. An electrical apparatus having a body for consuming power and constituted so as to be able to connect with a battery for supplying power to the body by discharging after being charged, has trouble recognition means for recognizing a trouble of the battery and resetting means for resetting the battery in accordance with the recognition by the trouble recognition means.
Claims19
Apparatus comprising:
- an electrical apparatus which consumes power;
- an intelligent battery operatively connected to said electrical apparatus and supplying power thereto by discharging after being charged;
- trouble recognition circuitry coupled to said battery and which recognizes a trouble of said battery;
- and
- a resetting element which resets said battery in accordance with the recognition by the trouble recognition circuitry.
Apparatus comprising:
- a system for consuming power;
- and
- a battery having a CPU for communicating with the system to supply power to the system by discharging after being charged;
- wherein said CPU of said battery is reset when said CPU hangs up and becomes inoperable.
Apparatus comprising:
- computer equipment;
- a battery operatively associated with said computer equipment and supplying power thereto by discharging after being charged;
- a controller communicating with said battery and controlling said battery;
- and
- a CPU which executes a utility program for the battery;
- and
- wherein said controller resets said battery in accordance with a designation from the utility program when it is recognized that a trouble occurs in communication with the battery.
Apparatus comprising:
- computer equipment;
- a battery connected to said computer equipment and supplying power thereto by discharging after being charged;
- a communication connection operatively associated with said battery and communicating with said battery in accordance with a predetermined protocol;
- a software-resetting element operatively associated with said battery and said communication connection and effective to software-resetting said battery by using said communication connection when a predetermined trouble occurs in the communication through said communication connection;
- and
- a hardware-resetting element operatively associated with said battery and effective to hardware-reset said battery in order to forcibly initialize said battery.
Apparatus comprising:
- an intelligent battery suitable to be connected to an electrical apparatus to supply power thereto by discharging after being charged and having
- a cell for supplying power;
- a CPU for recognizing a state of said cell and communicating with the electrical apparatus;
- and
- resetting circuitry which resets said CPU under the control of the electrical apparatus.
A method comprising the steps of:
- determining whether a predetermined trouble occurs in the communication between an intelligent battery and an electrical apparatus body to which the battery is connected to supply power by discharging after being charged;
- prompting a user to execute a software reset of the battery when it is determined that a predetermined trouble occurs;
- and
- resetting the battery with a software command when software resetting is designated by a user.
A method comprising the steps of:
- determining whether communication is possible between an intelligent battery and an electrical apparatus body to which the battery is connected to supply power by discharging after being charged;
- hardware-resetting the battery when the communication is not possible.
A method comprising the steps of:
- determining whether a predetermined trouble occurs in the communication between an intelligent battery and an electrical apparatus body to which the battery is connected to supply power by discharging after being charged;
- executing a software reset of the battery in accordance with a determination that the predetermined trouble occurs;
- and
- hardware-resetting the battery in the event that software resetting does not normally end.
