A bad battery will have short I-phase and Uo-phase, but there is a risk of gassing, further damaging the battery. If a battery is connected to a significant load during charging, the end of the Uo-phase may never be reached and the battery will gas and be damaged, depending on the charge current relative to the battery capacity.
A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
An AA battery in a glass of tap water with salt showing hydrogen produced at the negative terminal. Electrolysis of water is using electricity to split water into oxygen (O 2) and hydrogen (H 2) gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be ...
This type of power supply is called two-quadrant power supply. In contrast, a conventional power supply can only source current when the voltage is positive. A battery simulator may be able to set the simulated battery voltage either remotely via PC or manually. Often battery simulators have built-in voltage and current display and monitoring.
Higher-power fast charge solutions for mobile devices rely on a charge pump instead of a buck converter to reduce the voltage, as higher efficiency reduces heat generation. The Samsung Galaxy S23, which takes an input current of 3 A, can charge its internal battery packs at 6 A thanks to a 2:1 current pump. [3]
The energy used to charge rechargeable batteries usually comes from a battery charger using AC mains electricity, although some are equipped to use a vehicle's 12-volt DC power outlet. The voltage of the source must be higher than that of the battery to force current to flow into it, but not too much higher or the battery may be damaged.
