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.
where or Vtsat is the threshold voltage measured at a supply voltage (the high drain voltage), and or Vtlin is the threshold voltage measured at a very low drain voltage, typically 0.05 V or 0.1 V. is the supply voltage (the high drain voltage) and is the low drain voltage (for a linear part of device I-V characteristics). The minus in the ...
Charge cycle. A charge cycle is the process of charging a rechargeable battery and discharging it as required into a load. The term is typically used to specify a battery's expected life, as the number of charge cycles affects life more than the mere passage of time. Discharging the battery fully before recharging may be called "deep discharge ...

Rechargeable battery. A battery bank used for an uninterruptible power supply in a data center. A rechargeable lithium polymer mobile phone battery. A common consumer battery charger for rechargeable AA and AAA batteries. A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator ), is a type of electrical ...
To make it cost-effective with the state’s new incentives, homeowners now need to install batteries in addition to solar panels, but that can cost an additional $10,000 to $20,000 or more. “It ...
This pair of Dr. Scholl's Time Off Sneakers was recommended by many social media users, with one even calling them “literally the comfiest shoes” she’s ever worn. And now they're on sale for ...
Battery eliminator circuit. 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.
