Battery Control and Protective Element Validation Method
First Claim
1. A method for controlling output of a power source, comprising:
- determining a temperature of the power source;
selecting a handshake signal to be sent to a switch, wherein the handshake signal is selected based on the temperature;
transmitting the selected handshake signal to the switch;
selecting a power distribution scheme depending on the selected handshake signal; and
causing a distribution of an amount of power from the power source in accordance with the selected power distribution scheme.

Abstract
A method, system and device for discharging power or validating protective elements of a power source to ensure proper functioning of a tool at various temperatures. The power source communicates with a switch using handshake signals to establish a scheme for power distribution depending on the temperature of the power source. The power source can discharge power at a normal start-up rate or a slower start-up rate depending on the temperature of the power source. Handshake signals can also be used to validate protective elements, where the protective elements respond to wake-up signals with respective handshake signals indicating that the protective elements are functioning property.
