INTEGRATED BATTERY SAFETY INTERLOCK
First Claim
1. A battery system, comprising:
- a first terminal and a second terminal configured to electrically couple to an electronic component;
a current source electrically coupled to the first terminal;
a control system configured to;
direct an asynchronous current from the current source to the first terminal according to a pattern;
receive a current signal status from a current detector, wherein the current signal status is associated with a second current received via the second terminal; and
disconnect the electronic component from the first terminal or the second terminal when the current signal status does not correspond to the pattern.

Abstract
The present disclosure includes a battery system that may include a first terminal and a second terminal electrically coupled to an electronic component. The system may also include a current source electrically coupled to the first terminal. The system may also include a control system that may direct an asynchronous current from the current source to the first terminal according to a pattern and receive a current signal status from a current detector. The current signal status is associated with a second current received via the second terminal. The control system may disconnect the electronic component from the first terminal or the second terminal when the current signal status does not correspond to the pattern.
