Claims45
A method of data transfer between a power tool and a battery pack, the method comprising:
- providing the battery pack including at least one battery cell and a memory;
- connecting the battery pack with the power tool having provisions to transmit information relating to the power tool;
- identifying the power tool to which the battery pack is connected;
- transmitting the information from the power tool to the battery pack;
- storing the transmitted information in the data storage provisions of the battery pack.
A method of data transfer between a power source module and a battery pack, the method comprising:
- providing a battery pack including at least one battery cell, memory with stored information, a housing defining an interior region, and a battery charging circuit disposed in the interior region of the housing;
- connecting the battery pack with a power source module;
- transferring electrical power from the power source module to the battery pack to thereby charge the at least one battery cell;
- transmitting the stored information from the memory of the battery pack to the power source module.
A method of data transfer between a power source module and a battery pack, the method comprising:
- providing a battery pack including at least one battery cell, a housing defining an interior region, memory with stored information, and a battery charging circuit disposed in the interior region of the housing;
- connecting the battery pack with a power source module;
- wherein the power source module includes provisions to identify the battery pack;
- identifying the battery pack to which the power source module is connected;
- transferring electrical power from the power source module to the battery pack to thereby charge the at least one battery cell;
- transmitting the stored information from the memory of the battery pack to the power source module;
- the power source module transferring the transmitted information to a remote server.

- a power tool;
- a battery pack including at least one battery cell and data storage provisions, the battery pack for providing power to the tool and removable from the power tool;
- a charger including an AC/DC power circuit and provisions for memory storage;
- wherein at least one of the power tool and the battery pack includes provisions for enabling data transfer between the battery pack and the power tool.
A system for charging a battery for a power tool, the system comprising:
- a power tool;
- a battery pack including at least one battery cell and data storage provisions;
- a charging shoe including an interface for connection to the battery pack and a memory for storing information relating to the power tool or use of the power tool.
A system for charging a battery for a power tool, the system comprising:
- a power tool;
- a battery pack including at least one battery cell, USB communication provisions, and a USB connector;
- a charger including an AC/DC power circuit and provisions for memory storage;
- a remote server;
- wherein at least one of the power tool and the battery pack includes provisions for enabling data transfer between the battery pack and the power tool;
- wherein at least one of the battery pack and the charger includes communication provisions to transfer data between the battery pack and the charger;
- wherein the charger includes provisions to transfer data between the charger and the remote server.
