# Charging battery Definition and 3 Discussions

A charging station, also called electric vehicle charging station, electric recharging point, charging point, charge point, electronic charging station (ECS), and electric vehicle supply equipment (EVSE), is a machine that supplies electric energy to charge plug-in electric vehicles—including cars, neighborhood electric vehicles, trucks, buses and others.
Some electric vehicles have on-board converters that plug into a standard electrical outlet or a higher voltage outlet. Others use custom charging stations.
Charging stations provide connectors that conform to a variety of standards. For common direct current rapid charging, chargers are equipped with multiple adaptors such as Combined Charging System (CCS), CHAdeMO, and AC fast charging.
Public charging stations are typically found street-side or at retail shopping centers, government facilities and parking areas.

1. ### Does DC or AC work best for charging most industrial batteries?

I have a source of electricity that's alternating but at variable frequencies. So an asynchronous alternating current of sorts if you will. Can industrial rechargeable batteries be charged like this efficiently? Or would DC current work best? Or normal AC?
2. ### Could you check this Li-ion charging circuit?

Can secondary cell can be described in circuit simulator?? With other symbols like capacitor. Also I wonder if there's a program that provide secondary cell(like Li-ion battery). Please help me
3. ### Charging a battery and monitoring the current w/ an instrumentation amp

Homework Statement Homework Equations CMRR = Av/Acm Acm= Δ/R , Δ = (2 x Tolerance of Resistor).R The Attempt at a Solution I have to admit I am a bit confused by the premise of the problem. My understanding is Vout is used to vary Vcharge in some way, so that Icharge is always 1.3 A. Then...
