Understanding the Basics of Electric Vehicle Technology

EV technology is rapidly growing in popularity as a replacement for fuel-based vehicles. It has been seen as a solution to the problem of rising pollution and global warming caused by fossil fuels.

EVs use batteries to power the motor and charge from the grid when the battery is depleted. EVs also have regenerative braking that captures energy from the vehicle’s momentum and feeds it back into the battery to help reduce the car’s dependency on the gas engine.

Electric Vehicle Batteries are getting better

The Electric Vehicle battery is the heart of every EV, providing the energy for its motors. It consists of a series of lithium-ion cells, an electrolyte and separator.

The cells are grouped together into modules, which in turn are connected to form packs. Each module is able to supply enough energy for an entire vehicle.

Unlike traditional vehicles, which are powered by a fuel tank, EVs can be recharged at home or on the go using fast chargers and a variety of power sources, including electricity from the grid or from renewables like solar or wind.

However, charging a battery to full capacity takes much longer than filling a traditional car’s fuel tank. Automotive suppliers and academics are working on ways to reduce this time.

Eventually, the batteries used to power EVs will need to be recycled or fed back into the energy cycle for factories and homes once their life is over. Smart battery management technology could then give these EVs a second life, storing green energy or providing emergency backup power.

New generation motors

Unlike ICE (internal combustion engine) vehicles, EVs run on electricity. This can be from a number of different sources, including fossil fuels and renewable energy such as wind power and solar power or a combination of them.

During a normal drive, the battery stores power and provides it to the motor that drives the wheels. Electric vehicles can also use regenerative braking to recharge the batteries.

Most Electric Vehicles only have one motor, but high-end Tesla and BMW models have two or three – or even all-wheel drive.

There are three different types of motors in an EV: AC, brushless, and permanent magnet. In contrast to brushless, which lacks a stator, permanent magnet motors feature an iron rotor with permanently mounted magnets in lengthwise slots arrayed in multiple lobes. The lobes interact with the stator’s magnetic field, called the RMF, to create reluctance torque.

Electric Vehicle Charging Stations

EV charging stations (also known as EVSE or charge points) supply electricity to electric vehicles. They also provide a range of other services, such as power grid monitoring, facility metering, and energy controllers to control the station’s use.

Depending on your needs and budget, there are several different types of EV charging stations: Level 1 chargers, Level 2 home chargers, and Level 3 public chargers. Each type of charging station offers a unique set of benefits to its users.

Level 1 chargers, which are often used at home, charge an EV from an outlet with a standard 120-volt AC plug. Using these types of chargers, you can expect to charge your car from empty in about 40 hours.

EV Transportation

EV technology is used in a wide range of vehicles, including hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and battery electric vehicles (BEVs). The motors are driven by electricity stored in a battery, which can be charged at home or at an EV charging station.

Compared to internal combustion engines, EVs have little or no emissions. They use the energy of the sun, wind, or other natural resources to produce the electricity needed to power their on-board motors and batteries.

Replenishing an Electric Vehicle’s battery pack isn’t as fast as filling an internal-combustion vehicle’s fuel tank, however, and automotive suppliers and academics are looking to reduce that time. DC fast-charging is the fastest method available, with a top-off from empty to 80% in 18 minutes.

NREL researchers are working to integrate EVs with the grid, developing strategies that optimize energy efficiency in a larger context. They are using a national evaluation platform to test charging systems, integrating hardware-in-the-loop simulations with building, transportation, and electricity supply systems.
