Abstract: A power supply device has a power source providing a voltage and a monitoring device electrically connected to the power source. The monitoring device measures the voltage, the current, and the temperature of the power source when power is drawn from the power source, and interrupts the power draw if the voltage drops below a cutoff threshold. The cutoff threshold depends on the temperature at the power source and the current.

Abstract: Disclosed is a method for controlling the operating point (AP, AP1, AP2) of a battery (1), such as a lithium ion battery, a nickel metal hydride battery or a lithium polymer battery.
