ELECTRONIC EQUIPMENT AND CHARGING METHOD THEREFOR
First Claim
1. An electronic equipment comprising:
- a main body block including an external power supply connection terminal capable of being connected to an external power supply and a first charge control block for controlling contact charging of a battery cell from the external power supply by way of the external power supply connection terminal; and
a battery pack includinga thermistor for enabling the first charge control block to monitor a temperature of the battery cell by way of a thermistor terminal,a power receiving control block for determining whether or not to perform contactless charging of the battery cell according to whether or not a constant voltage is applied to the thermistor terminal from the first charge control block,a second charge control block for performing contactless charging of the battery cell with the electric power transferred to a secondary coil from a charging rack, the charging rack having a primary coil for transferring electric power to the secondary coil on a basis of a determination result rendered by the power receiving control block and a power transfer control block for controlling transfer of electric power from the primary coil, andthe battery cell.

Abstract
An objective of the invention is to make it possible to switch between contact charging and contactless charging without involvement of an increase in the number of constituent components and complication of charge control. An electronic equipment has a main body block and a battery pack. The battery pack has a power receiving control block for determining whether or not to perform contactless charging of a battery cell, based on whether or not a constant voltage is applied to a thermistor terminal from a first charge control block of the main body block and a second charge control block that performs contactless charging of the battery cell with electric power transferred from a charging rack to a secondary coil on a basis of a determination result of the power receiving control block.

5. A charging method for an electronic equipment including a main body block comprising a first charge control block for controlling contact charging of a battery cell by way of an external power supply connection terminal capable of being connected to an external power supply, and a battery pack including a thermistor for monitoring a temperature of the battery cell from the main body block and a second charge control block for performing contactless charging of the battery cell with the electric power transferred to the secondary coil from a charging rack that has a primary coil for transferring electric power to a secondary coil and a power transfer control block for controlling transfer of electric power from the primary coil, the method comprising:
-
a determination step of determining, by means of a power receiving control block of the battery pack, whether or not a constant voltage is applied from the first charge control block to a thermistor terminal connected to the thermistor of the battery pack; and a charging step of the second charge control block of the battery pack performing contactless charging of the battery cell with electric power that is transferred from the primary coil to the secondary coil by the power transfer control block of the charging rack when the constant voltage is determined to not be applied to the thermistor terminal from the first charge control block in the determination step.
