Abstract
A Li ion battery main body and a charge/discharge circuit for controlling charge/discharge of the Li ion battery main body in accordance with a difference between an NiH battery and an Li ion battery are arranged in a battery pack housing having the same shape, mounting mechanism, and connection terminals as those of a standard battery pack using the NiH battery. The battery pack also includes a discrimination terminal for discriminating the type of battery.

20. A battery discrimination control method executed by a data processing apparatus in which one of a first type of battery pack and a second type of battery pack having charge/discharge characteristics different from those of said first type of battery pack can be mounted in a battery pack mounting portion, comprising the steps of:
-
(a) determining, on the basis of information from a temperature detection terminal of connection terminals of said battery pack mounting portion, if a temperature of one of said first type of battery pack and said second type of battery pack falls within an appropriate temperature range; (b) determining, if the temperature is determined to be within the appropriate temperature range in step (a), if one of said first type of battery pack and said second type of battery pack was mounted in a previous operation of the data processing apparatus; (c) inputting discrimination information of the mounted battery pack through a discrimination terminal arranged independently of said temperature detection terminal of said connection terminals of said battery pack mounting portion if none of the first type of battery pack and said second type of battery pack is determined in step (b) to have been mounted in the previous operation of the data processing apparatus; (d) determining on the basis of the discrimination information input if the input discrimination information is unique to said second type of battery; (e) discriminating that said first type of battery pack is mounted in said battery pack mounting portion when the discrimination information is determined in the information determination step (d) not to be unique to said second type of battery pack; (f) discriminating that said second type of battery pack is mounted in said battery pack mounting portion when the discrimination information is determined in the determining step (d) to be unique to said second type of battery pack; and (g) releasing an input state of the discrimination information input in the discrimination information inputting step upon execution of at least one of the discriminating step (e) and the discriminating step (f). - View Dependent Claims (21)
