A charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries to protect against electrical overload, overcharging, and may protect against overvoltage. [1] [2] This prevents conditions that reduce battery performance or lifespan and may pose a safety risk.
IUoU is a DIN -designation [1] (DIN 41773) for a lead-acid battery charging procedure that is also known as 3-stage charging, 3-phase charging, or 3-step charging. It consists of three phases (or stages), to be executed by a battery charger. The three phases are: I-phase (constant electric current ), Uo-phase (constant over- voltage ), and U ...
Charge sharing in digital electronics. In digital electronics, charge sharing is an undesirable signal integrity phenomenon observed most commonly in the Domino logic family of digital circuits. The charge sharing problem occurs when the charge which is stored at the output node in the precharge phase is shared among the output or junction ...
Method of image charges. The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics. The name originates from the replacement of certain elements in the original layout with imaginary charges, which replicates the boundary conditions of the problem (see ...
The triboelectric effect (also known as triboelectricity, triboelectric charging, triboelectrification, or tribocharging) describes electric charge transfer between two objects when they contact or slide against each other. It can occur with different materials, such as the sole of a shoe on a carpet, or between two pieces of the same material.
A charge amplifier is an electronic current integrator that produces a voltage output proportional to the integrated value of the input current, or the total charge injected. Schematic of a charge amplifier with a piezoelectric sensor. The amplifier offsets the input current using a feedback reference capacitor, and produces an output voltage ...
Charge control. Charge control is a technology that lets an electric utility control, in real time, the charging of a gridable (plug-in) vehicle, such as a plug-in hybrid (PHEV) or a battery electric vehicle (BEV). Through charge control, the utility is able to postpone charging of the vehicle during time of peak demand.
Just look at 8-month-old Liberty, AKA Libby. This little angel is only just learning how to be a dog after being rescued by Buffalo Pug and Small Breed Rescue, but her time in her foster home has ...
