Patent ID: 8284537

Claim:
A battery with electrostatic discharge protection, comprising: a case including a conductive part; a circuit board set inside the case and including a ground node and a conditional conducting path which connects between the conductive part and the ground node and comprises: a conducting component having one end physically contacting the conductive part; and an electrostatic discharge component connecting between another end of the conducting component and the ground node, functioning as a low impedance circuit when the voltage variation between the two ends of the electrostatic discharge component reaches a predetermined condition, and functioning as a high impedance circuit when the voltage variation between the two ends of the electrostatic discharge component falls without the predetermined condition, wherein the predetermined condition accords with the characteristic of the electrostatic discharge component; and a voltage source disposed inside the case and having one electrode electrically connecting to the ground node and receiving charges released from the conductive part to the ground node via the conditional conducting path.
