A charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries. [1] It prevents overcharging and may prevent against overvoltage, which can reduce battery performance or lifespan, and may pose a safety risk. It may also prevent completely draining ( deep discharging ) a battery, or perform controlled discharges, depending on the battery technology, to protect battery life. [2][3] The terms charge controller or charge regulator may refer to either a stand-alone device, or to control circuitry integrated within a battery pack, battery-powered device, or battery recharger. [4]

Simple charge controllers stop charging a battery when they exceed a set high voltage level, and re-enable charging when battery voltage drops back below that level. Pulse width modulation (PWM) and maximum power point tracker (MPPT) technologies are more electronically sophisticated, adjusting charging rates depending on the battery's level, to allow charging closer to its maximum capacity.[8] Charge controllers may also monitor battery temperature to prevent overheating. Some charge controller systems also display data, transmit data to remote displays,[8] and data logging to track electric flow over time.

The two included battery packs double as controller grips, similar to the ones we've seen in the standard Nyko Charging Station. The only difference with these cases is that they offer access to the Wii sync buttons via a tiny hole placed in the casing. Nyko cleverly included a funny-looking accessory to reach the button, a plastic sync tool.

by Joe Buxton Lithium-Ion (Li-Ion) batteries are gaining popularity for portable systems due to their increased capacity at the same size and weight as the older NiCad and NiMH chemistries. For example,a portable computer equipped with a Li-Ion battery can have a longer operating time than a similar computer equipped with a NiMH battery. However, designing a system for Li-Ion batteries requires special attention to the charging circuitry to ensure fast, safe, and complete charging of the battery.
