70:. This prevents conditions that 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. 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, and/or

by Huawei, have taken the counter approach by increasing the charging current. Since the voltage that arrives at the end device matches the optimum battery charging voltage, no conversion inside the end device is necessary, which reduces heat there. However, unlike the charging protocols that only

A charge controller with MPPT capability frees the system designer from closely matching available PV voltage to battery voltage. Considerable efficiency gains can be achieved, particularly when the PV array is located at some distance from the battery. By way of example, a 150 volt PV array

The voltage range of the successor Pump
Express Plus 2.0 is between 5 volts and 20 volts, with 0.5 volts steps. The Quick Charge 3.0 protocol supports finer-grain voltage levels with 0.2 volts steps and has a lower minimum voltage of approximately 3.3 volt. According to

226:, Quick Charge 3.0 starts at 3.2 volts with 0.2 volts between each step and goes up to 20 V (3.2 V, 3.4 V, 4.6 V, ..., 19.8 V, 20 V). The site "powerbankexpert.com" claims that the protocol has a minimum voltage of 3.6 volts.

Pump
Express Plus supports elevated voltage levels of 7, 9 and 12 volts, whereas the specification for Quick Charge 2.0 lacks the 7-volt level. A 20-volt level was added in a revision named "class B" of the specification.

Charge controllers may also monitor battery temperature to prevent overheating. Some charge controller systems also display data, transmit data to remote displays, and data logging to track electric flow over time.

connected to an MPPT charge controller can be used to charge a 24 or 48 volt battery. Higher array voltage means lower array current, so the savings in wiring costs can more than pay for the controller.

elevate voltage, the higher currents would produce more heat in cables' copper wires, making it incompatible with existing cables, and require special high-current cables with thicker copper wires.
110:(LVD), a separate circuit which powers down the load when the batteries become overly discharged (some battery chemistries are such that over-discharge can ruin the battery).

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.
