In battery-powered equipment, a battery eliminator circuit (BEC) is an electronic voltage regulator used to power a subsystem at a different voltage without the need for a supplemental battery. BECs are commonly used in radio-controlled models , which need separate voltages to power the motor and the R/C equipment.
Whether a charger can charge the battery depends largely on the dimensions of the battery and internal chemistry (I.E., disposable batteries cannot be charged). Testing a nine-volt battery can be done using a multi-meter by probing the voltage across the two terminals.
To prevent adverse effects, a battery management system or battery charger may keep the battery from extreme levels regarding SoC, thereby limiting the SoC to a reduced range between 0 % and 100 % and decreasing depth of discharge below 100 % (see example below). This corresponds to the DoD in the sense of definition (1).
In the case of charging a capacitor from a linear DC voltage, like that from a battery, the capacitor will still appear as a short circuit; it will draw current from the source limited only by the internal resistance of the source and ESR of the capacitor. In this case, charging current will be continuous and decline exponentially to the load ...
The energy density (energy/volume) of a new LFP battery is some 14% lower than that of a new LiCoO 2 battery. [44] Since discharge rate is a percentage of battery capacity, a higher rate can be achieved by using a larger battery (more ampere hours) if low-current batteries must be used.
The FUV platform uses pouch cells with a Lithium-Nickel Manganese Cobalt (NMC) battery chemistry [25] of about 30 Ah each from Farasis Energy, which are the same as Zero Motorcycle's cells or the cells in the Polaris / Brammo Empulse. The cells combine to a total of 19.2 kWh in the FUV battery in a 28s 6p configuration.
