Battery with communication interface
First Claim
1. A battery, comprising:
- a battery housing with an electrical connection consisting of a first positive direct current (DC) terminal and a first negative DC terminal, and further comprising therein;
at least one battery cell coupled through respective connections with the first positive and negative DC terminals, respectively;
a first receiver having an input and an output;
a first transmitter having an input and an output;
a first digital processor and memory, the first digital processor is coupled to the output of the first receiver and to the input of the first transmitter,a first RF coupler coupled with the input of the first receiver and the output of the first transmitter, wherein the first receiver is an RF receiver and the first transmitter is an RF transmitter, and wherein the first RF coupler is arranged adjacent to the electrical connection between the first positive DC terminal and the at least one battery cell such that RF signals are transmitted via the electrical connection.

Abstract
A standard two terminal battery package is configured to communicate with an external charger or load, without requiring modification to the battery mechanics and/or high current circuit components integral with the battery. A transmitter and receiver (transceiver) are incorporated into the battery housing. An associated battery charger and/or load, e.g., tool, appliance, vacuum, etc., has a corresponding transceiver configured to communicate with the battery transceiver. A microcontroller may be coupled to the transceiver. Serial number verification between the battery and tool load can be verified. Sensors for temperature, voltage, pressure and pH may be coupled between the battery and microcontroller for monitoring battery temperature, voltage charge and condition during operation or charging thereof. Information from these sensors and more may be communicated from the battery to the load or battery charger. Furthermore, the battery charger may communicate over the Internet for battery operational history collection and theft identification.
