Abstract

Disclosed is a method of detecting a health state of a battery, in a power supply circuit having a charger and an energy storage device and for a pulsed load having a repetition interval, the method comprising: controlling a charging current of the energy storage device, by controlling an operating frequency of the charger, to recharge the energy storage device over the repetition interval at an optimised charger operating frequency; at least one of: comparing the optimised charger operating frequency with a threshold frequency, and comparing a rate-of-change of the optimised charger operating frequency with a threshold rate-of-change; and indicating an end-of-life state of the battery in response to at least one of: the optimised charger operating frequency exceeding the threshold frequency, and the optimised charger operating frequency exceeding the threshold rate-of-change. Other embodiments are disclosed.
