The Smart-UPS is a series of enterprise-level uninterruptible power supplies (UPS) made by American Power Conversion (APC). [1] Most of the units have a SmartSlot (with the exception of SC and SMC series) which accepts an optional interface card providing features ranging from network connectivity to temperature and humidity monitoring.

A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
A smart battery or a smart battery pack is a rechargeable battery pack with a built-in battery management system (BMS), usually designed for use in a portable computer such as a laptop. [ 1 ] [ 2 ] In addition to the usual positive and negative terminals, a smart battery has two or more terminals to connect to the BMS; typically the negative ...
Smart charging transfers a portion of the peak load to off-peak hours. The predictability of energy demand is also improved because of the capability to use V2G as a backup. Study shows that a smoother and more predictable energy demand curve will boost the proportion of green energy in total energy production.
A UPS designed for powering DC equipment is very similar to an online UPS, except that it does not need an output inverter. Also, if the UPS's battery voltage is matched with the voltage the device needs, the device's power supply will not be needed either. Since one or more power conversion steps are eliminated, this increases efficiency and ...
The company reached 100,000 chargers in September 2019, while adding more than 2,000 charging locations per month [13] ChargePoint went public through a special-purpose acquisition company ("SPAC") reverse merger in February 2021.
In May 2000, ZAP introduced a line of sea scooters with battery-powered propulsion, [26] and the KICK-PUSH Scooter. [27] Also, the company appointed John Dabels as President of ZAP following the acquisition of EMB in 1999. Dabels was the former marketing director of the GM EV1 program. [25] [28]
Batteries kick in only during extended interruptions, e.g., if the mains power or a fuel cell fails, which lengthens battery life. Uninterruptible power supplies (UPS) may be powered by supercapacitors, which can replace much larger banks of electrolytic capacitors. This combination reduces the cost per cycle, saves on replacement and ...
