The national grid delivers AC (Alternating Current), but electric cars need DC (Direct Current) to charge their battery pack. An AC charger supplies the EV's onboard charger, which then converts the AC power to DC allowing the battery to charge. The size of the onboard charging device is constrained by space.An electric vehicle battery
The battery is made up of two electrodes in an electrolyte. The electrolyte is where the exchange of ions takes place to produce electricity. The lithium ions act as the charge carrier, allowing for the simultaneous exchange of positive and negative ions in the electrolyte.At its most basic, an EV charger pulls an electrical current from either a 240v outlet or the grid it's hardwired to and delivers that electricity to the vehicle, just like any other appliance or device you charge by plugging into the wall.
What is a charging cycle EV : Simply put, a charging cycle is a process of fully charging, then discharging the array of cells.
How does charging work
During charging, the battery functions as an electrolytic cell. When the cell is connected to an outside energy source, the electrons in the cathode are forced to flow back to the anode. There is movement of electrons from an external power source to the anode. On the other side, electrons are removed from the cathode.
What are the four types of EV : System Architecture of 4 types of electric cars is as follows:
Battery Electric Vehicles (BEVs) BEVs are also known as All-Electric Vehicles (AEV).
Hybrid Electric Vehicle (HEV): HEVs are also known as series hybrid or parallel hybrid.
Plug-in Hybrid Electric Vehicle (PHEV):
Fuel Cell Electric Vehicle(FCEV):
But the batteries in EVs aren't a huge version of that single cell. Instead, they're made up of hundreds, if not thousands, of individual cells, usually grouped together into modules. Up to several dozen modules can reside within a battery pack, which is the complete EV battery. On a general classification, there are three types of EV charging, which are:
Level 1 (Slow Charging)
Level 2 (Fast Charging)
Level 3 (Rapid Charging)
Is EV charging AC or DC
When it comes to electric vehicles, the converter is built inside the car. It's called the "onboard charger" though it really is a converter. It converts power from AC to DC and then feeds it into the car's battery. This is the most common charging method for electric vehicles today and most chargers use AC power.There are three EV charging levels; Level 1, Level 2, and Level 3. There are differences between each charging level. However, as a general rule, the higher the Level, the higher the power output from the charger and the faster it can charge.All AC electric vehicle plugs feature a three-phase capability. This means that technically all EVs can charge with a three-phase charger, but not all EVs can charge at the high power rate delivered by high-capacity three-phase EV chargers. There are several EVs that limit AC fast charging at 11kW or less. Wireless chargers produce a small, alternating magnetic field, which then produces a small, alternating current inside a coil in the target phone. A simple voltage rectifier then turns it in to DC that can charge the phone.
How are EV charging stations powered : Charging stations are powered by whatever the power grid runs on, which might include oil, coal, and natural gas. If you want to ensure that your car is powered by renewable energy, you'll need to seek out charging stations that are powered by wind or solar.

How many volts is EV
Most electric vehicles use at least 400 volts, with larger vehicles requiring 800 volts. With EV manufacturers aiming to create products to are more energy-efficient, higher voltages enable them to create batteries that use much fewer materials, allowing them to pay less for more energy. Electric car battery capacity
Lithium-ion battery capacity is measured in kWh (Kilowatt hours). The average capacity is around 40kWh, but some cars now have up to a 100 kWh capacity.Types of EV Chargers

How many kW to charge an EV : A 7kW home charger will charge a typical 60kWh electric car battery from empty-to-full in just under 8 hours. The perfect amount of time to fully recharge your EV battery while you sleep. A slower home charger rated at 3.7kW would take around 16 hours to do the same.
