Portable EV chargers are electric devices that convert alternating current to direct current. The electricity is then used to charge an electric car battery. Once an electric car battery has enough charge, it can perform a number of functions, including operating the engine and powering onboard electronics.
What Types of Electric Vehicle Chargers Are Available?
There are three types of portable EV chargers currently in use inductive, conductive, and wireless charging systems. Each type of charger uses a different method to transfer energy from the power line to the vehicle’s battery pack.
- Inductive Charging
Inductive charging systems use an electromagnetic field to transfer electrical energy between two objects. When the car’s battery is placed on a charging plate or mat, the “power” lines in the mats are energised by electricity flowing through the wires that connect them to the power grid and the vehicle’s controller unit or onboard computer. As a result of this electric current, an electromagnetic field is created that produces currents in coils beneath the car’s floorboards as they pick up energy from the plates. This energy then flows through wires to the battery pack and powers it.
- Conductive Charging
Conductive charging systems use a type of cord that can transfer energy from the power grid to the vehicle’s battery pack. This system uses cables that plug into the car’s battery pack and into an electric outlet at a home or business. The electric outlet then transfers electricity to the vehicle’s battery in a similar fashion as a cordless drill does.
- Wireless Charging Systems
Wireless charging systems use inductive coupling to transfer power from metal disks placed atop the car being charged. One disk is attached to the car, while another disk is attached to an electric current power source. As a result, when the disks are placed close enough together, an electromagnetic field is created between them and allows electricity to flow between them.
Are Portable Electric Chargers Enough For A Vehicle?
Portable electric car chargers are enough for many electric vehicles. The Nissan Leaf, Mitsubishi i-MiEV, Chevy Volt, and Fisker Karma are all capable of being charged using portable EV chargers.
The Tesla Model S and BMW i3, however, have larger battery packs than most other EVs on the market and require special charging stations with higher power outputs to charge the car faster. Some of these special stations are able to charge a car in just 30 minutes. Others, such as Tesla’s SuperCharger Stations can recharge batteries in as little as 20 minutes. So the answer depends on the kind of vehicle you drive. If your manufacturer has indicated that the model will require a charging station specifically, then portable car chargers may not do the job for you.
Conclusion
Portable EV chargers are a great deal for most electric vehicles. They can help charge your vehicle on the go. Help you out in emergencies, and just provide an all-around energy supply. Smaller cars and vehicles are easily charged by these chargers. They could charge the vehicle at a 6-7kw rate at once, so definitely grab one for yourself.
