BATTERY PACK FOR ELECTRIC POWER TOOL, AND BATTERY CONNECTION DEVICE
First Claim
1. A battery connection device that is electrically connected to a battery pack for electric power tools, the device comprising:
- an authentication data creating unit that creates authentication data;
a conversion unit that performs a first conversion of the authentication data created by the authentication data creating unit;
a transmission unit that transmits to the battery pack the authentication data created by the authentication data creating unit when the battery pack is electrically connected to the battery connection device;
a receiving unit that receives from the battery pack a battery-side conversion result that is data obtained after the authentication data is converted by the battery pack;
a reverse conversion unit that, on an assumption that the battery pack as an authentic product creates the battery-side conversion result by performing the first conversion and further a second conversion on the authentication data, performs a reverse conversion of the second conversion on the battery-side conversion result received by the receiving unit; and
a determination unit that compares a result of the reverse conversion performed by the reverse conversion unit with a result of the first conversion performed by the conversion unit and determines whether or not the battery pack is an authentic product,

Abstract
A battery connection device is provided with an authentication data creating unit that creates authentication data, a conversion unit that performs a first conversion of the authentication data, a transmission unit that transmits the authentication data to a battery pack, a receiving unit that receives from the battery pack a battery-side conversion result that is data obtained after the authentication data is converted by the battery pack, a reverse conversion unit that, on an assumption that the battery pack creates the battery-side conversion result by performing the first conversion and a second conversion on the authentication data, performs a reverse conversion of the second conversion on the battery-side conversion result, and a determination unit that determines whether or not the battery pack is an authentic product by comparing a result of the reverse conversion with a result of the first conversion.
