You can read the following article to find out how electric cars work and the difference between pure electric and hybrid cars.
What is the working principle of an electric car engine?
An electric car runs on electricity. The car plugs into a charging station. The batteries store electricity and charge the electric motor. Electric cars are lighter than traditional fuel-powered vehicles and can accelerate faster.
What are the types of electric cars?
There are many types of electric vehicles (E.Vs). Electric vehicles can only run on electricity. Some can run on diesel or petrol. These cars are called hybrid electric vehicles. You can find the answer of how electric cars work?
Plug-in electrics are powered entirely by electricity. This car produces no emissions and doesn’t need petrol or diesel to run.
- Plug-In Hybrid: These cars run primarily on electricity but can also use traditional fuel engines to run when they are low. These cars emit a lot of emissions when they are running on gasoline. These cars will not emit any if they are running on electric power. Plug-in hybrids can be connected to an electric outlet to charge their batteries.
- Hybrid-electric: They can run on diesel or petrol and have an electronic battery that can be charged using regenerative braking. The car can switch between regular fuel and ‘E.V.’ modes by pressing a button. These cars are not compatible with an electric source. They are solely dependent on petrol and diesel as their source of energy.
What’s the inside of an electric vehicle?
E.V.s are 90% smaller than ICE cars (Internal Combustion Motor). Here’s a list containing the essential components needed to keep an electric vehicle in operation (How electric cars work?):
- Electric Engine/Motor- It provides power to the wheels. It can be either DC/AC motor or an A.C. motor, but A.C. motors are more common.
- Inverter Converts the electric current into Alternating Currents.
- Drivetrain– Electric Vehicles come with a single-speed transmission that transfers power from the motor directly to the wheels.
- Battery – These batteries store the electricity needed to run an electric car. The battery’s power determines the range.
- Charging: It is a plug-in charging outlet, or E.V. charging station used to charge your battery.

Part 1: Electric Vehicles Overview
Since its inception, electric vehicle technology has improved rapidly. There are now many plug-in hybrids and battery electric vehicle options on the market. How do electric cars work? What are their benefits?
Let’s start with legacy vehicle technology: the internal combustion engines (or ICM). This vehicle’s propulsion is provided by a combustion motor that can only run on gasoline. This technology is reliable, established, and well-tested. However, it can consume large quantities of gasoline, making it expensive in many ways.
The electric vehicle drivetrain has arrived! The electric vehicle drivetrain is different from internal combustion technology. Electric vehicles or E.V.s are propelled using electromagnetism. These vehicles are powered by electricity that is stored in a lithium-ion battery. You can find E.V. technology in hybrid electric cars or HEVs, plug-in hybrid electric vehicles or PHEVs, and battery electric vehicles (BEVs).
The hybrid electric car was the first E.V. technology on the modern market. The increased fuel efficiency of HEVs like the Toyota Prius, Lexus CT-200-H, and Lexus CT-200-H makes them so popular. This vehicle combines an internal combustion engine with an electric motor and small batteries for storing electricity. The HEV is powered only by gasoline. However, you can use the vehicle’s battery to power its electric motor. The HEV stores electricity by recapturing the energy from regenerative brakes. The HEV is more fuel-efficient than ICE cars because it doesn’t use ICE vehicles.
The plug-in hybrid is powered by an internal combustion engine (the original hybrid) and an electric motor (the plug-in electric vehicle). However, the battery pack in the PHEV is much larger and can be charged via electric vehicle supply equipment (EVSE). The electric motor drives the vehicle until the battery is almost depleted. That allows the vehicle to continue operating in hybrid mode until its fuel is exhausted. By increasing the battery capacity and using electricity to power the vehicle, tailpipe emissions are reduced, and fuel- and efficiency are increased.
The battery-electric vehicle is the last type of electric vehicle technology. This vehicle is entirely powered by an electric motor, battery, and other components. BEVs can only be charged with EVSE and are not powered by gasoline. BEVs have the largest battery of all vehicle types. It is also fuel-efficient and emits zero tailpipe emissions.

Part 2: E.V.s and their range
The vehicle will determine how far you can travel with a full battery charge. Every model has a different range and battery size. Each model also offers different efficiency. You want an electric car you can use for regular trips without stopping to charge it halfway.
The range of vehicles that can be driven by each vehicle is different because they have different technologies. ICE vehicles (which are only powered by gasoline) can typically travel 350 to 450 mpg on a full tank.
Hybrid electric vehicles use less gasoline and can travel approximately 550-700 miles. However, the battery is only used to power the vehicle during normal driving cycles and is not used as a primary source for propulsion. The hybrid’s greater fuel efficiency and range are to regenerative braking.
A plug-in hybrid vehicle can run on an all-electric battery, which allows the vehicle to travel between 20 and 40 miles using only electricity. PHEVs can be used for everyday commutes or overnight charging via a standard outlet. When the battery is exhausted, you can use the hybrid mode to extend the range.
Finally, the battery-electric car has the most efficient and simple drivetrain. It typically ranges from 150 to 300 miles. You can charge BEVs overnight by using standard residential Level 2-EVSE.
Part 3: E.V. Regenerative Braking Modes
Regenerative braking makes an electric vehicle different from a conventional ICE car. A regenerative brake is an electric motor that operates in reverse. It applies a braking force by electromagnetism. That allows the vehicle to recapture some of its kinetic energy and charges the battery.
An E.V. such as the Tesla Model S will engage regenerative braking when the driver puts their foot on the accelerator. The Standard setting is the most powerful regenerative braking power. It captures the most energy and also reduces brake wear. Alternately, the “Low” setting uses a smaller regenerative braking force but still allows the vehicle more freedom to the coast than the “Standard.”
An E.V. such as the Tesla Model S has specific settings to control the operation of the brake systems when the vehicle is stopped or at very low speeds. “Creep,” which is designed to mimic the idling speeds of an ICE car, has been created. It uses regenerative brake and motor torque at low speeds. This feature is used most often when searching for a parking space.
Finally, the “Hold” setting continues to engage the regenerative braking system until the vehicle has come to a complete halt. This feature reduces brake wear and generates the greatest recaptured electric power. It activates the friction brakes when the vehicle is stopped completely. The vehicle will remain stationary until the driver presses on the accelerator, brake, or accelerator.
The brake pedal works in all braking modes and functions the same as normal vehicles.
Regenerative braking options vary depending on the vehicle’s make and type. For instance, the Nissan Leaf has three levels of reactive braking, while the Chevrolet Bolt uses paddles to depress the steering wheel. It can maximize regenerative braking and brings the vehicle to a complete halt.

Part 4: PHEV Drivetrain modes
Ford Fusion’s three driving modes, “Auto E.V.,” “E.V. Now,” and “EV Later,” each have its losses.
- Auto E.V.’s model incorporates an optimized mixture of gasoline and battery energy to maximize the use of both fuels. This mode allows for faster highway speeds.
- The “E.V. Now” mode depends entirely on the battery/electric drivetrain. It results in zero tailpipe emission, comparable to a car-electric hybrid.
- Finally, the “EV Later” mode preserves battery power for later use. This mode is perfect for trips that combine highway and in-town travel. It operates at highway speeds using the combustion engine and then reserves the energy to switch to “E.V. Now” mode in the latter part of the trip when it is most efficient.
Part 5: E.V. batteries: capacity and kWh explained
Kilowatts (kW) is a unit for power. A kilowatt-hour (kWh) refers to a unit of energy. It shows how much energy was consumed. A typical 100-watt home consumes 3,100 kWh per year. The average electric car uses 2,000 kWh per year.
Electric car charging
You can use a socket to charge your electric vehicle or plug it into a charging device. There are many charging stations available in the U.K, USA, and Europe to keep your vehicle fully charged when you go out. There are three types.
- Three-pin plug: This plug is a standard charger and can be used with any 13-amp charging socket.
- Socketed: It is a charging point from which you can connect a charger of Type 1 or 2 cables.
- Tether: It is also a charge point that can use with either Type 1 or 2 connectors.
Types of EVSE
All plug-in electric vehicles, including hybrids and battery electric cars, use electric vehicle supply electronics (EVSE) to charge their batteries and how electric cars work?.
- There are three main types of EVSE. The Level 1 charger is the first. These are typically portable cord sets that can be charged from a standard 120-volt household socket and provide approximately 2-5 miles of range each hour. This charger is the most affordable but does not offer the greatest daily range for charging vehicles. That is the best option for PHEVs with smaller batteries or BEV drivers who commute less to work.
- Level 2 chargers can deliver more energy per hour, and they can be powered by either 208 or 240 V. These chargers are usually installed on permanent pedestal-style or wall-mounted bases and are costlier. They can provide about 10 to 20 miles range per hour for a vehicle. It is the most widespread application for long-range BEVs.
- The final type of charger is the DC Fast Charger. It costs the most but provides the most power per hour. A DC Fast Charger standard can deliver 60 to 80 miles in 20 minutes. You can find these chargers most often along highways.

Part 6: Reporting Energy Consumption
Federal fleet vehicles must report their energy consumption to do business. ICE vehicles report their fuel consumption via the fuel card provider. This ICE can record every fueling transaction.
You can charge Electric vehicles on-site, off-site, at wall outlets, simple EVSE devices, or networked ones. Many of these charging units can record or store transactions, but some more affordable EVSEs won’t.
Telematics platforms typically capture kilowatt-hours and display them on an online dashboard. A fleet manager may choose a period to calculate a vehicle’s energy consumption in kilowatt-hours during a given period. That can be applied to all-electric vehicles within a fleet and provides the necessary information for federal fleet reporting.
Smart-EVSE or networked units can also provide valuable information about sources of energy consumption. These units have similar telematics-like online dashboards that track vehicle energy consumption. You can also access these dashboards through smartphones. Data may not be available if the vehicle is regularly charged on another network than the primary EVSE. To supplement their primary EVSE data, drivers can collect information from charging stations off-site.
You will often see information about energy consumption and vehicle efficiency on the vehicle’s dashboard. Some vehicle models have lifetime energy consumption. Federal fleet managers need to verify the number of kilowatt-hours used each year to complete their FAST reports. To determine the amount of energy used each year, fleet managers will need the vehicle’s lifetime efficiency divided by the vehicle efficiency.
(Annual miles)/(miles/kWh), = annual kWh
If all else fails, the U.S. Department of Energy’s Federal Energy Management Program provides a simple way for vehicle energy consumption to be estimated: Take the vehicle’s annual mileage reading, and multiply it by fuel economy (in kilowatts per mile on Fueleconomy.gov).
Annual miles x 1 kWh/mile = Annual kWh
