There are many differences between new energy vehicles (e.g., electric vehicles) and traditional fuel vehicles in terms of components and parts. Because of the significant differences in their power systems, energy supply methods, drive structures, etc., there are also significant differences in the design of their core components and building blocks. The following is a comparison of some key components of new energy vehicles and fuel vehicles: Powertrain New energy vehicles (electric vehicles) Electric motor: The core power system of an electric vehicle is an electric motor, usually an AC asynchronous motor or permanent magnet synchronous motor. These electric motors are smaller, lighter and simpler in structure compared to internal combustion engines.Battery pack: EVs rely on batteries as energy storage devices, commonly lithium batteries (e.g. Li-ion ternary batteries or lithium iron phosphate batteries), which are required to provide sufficient range and high charging and discharging efficiency.Electronic control system: The electronic control system of an electric vehicle manages the charging and discharging process of the battery, regulates the output power of the electric motor, and includes charging management, energy recovery system, and so on. Fuel Vehicles Internal Combustion Engine: Fuel vehicles rely on an internal combustion engine (e.g., gasoline or diesel engine) to provide power. Internal combustion engines require the combustion of fuel to produce mechanical power through the movement of pistons, involving complex combustion processes and exhaust gas treatment.Fuel System: Includes the fuel tank, fuel pump, fuel injection system, etc., which is used to store and deliver fuel to the engine.Exhaust system: The exhaust system of fuel vehicles includes catalytic converters, exhaust pipes, etc., which are used to reduce harmful emissions and treat exhaust gases produced by the engine. Transmission System New Energy Vehicles (Electric Vehicles) Single-speed transmission: Most EVs use a single-speed transmission (some high-performance EVs may have two- or multi-speed transmissions) because the electric motor works very efficiently and does not require complex multi-gear shifting.Reducer: Electric motors have high RPMs, so a reducer is usually installed after the motor to reduce RPMs and increase torque output. Fuel Vehicles Multi-Speed Transmission: Fuel vehicles typically use either a manual or automatic transmission, providing multiple gears for the driver to choose from to accommodate different speeds and loads.Clutch (manual transmission)/torque converter (automatic transmission): Used to switch between gears to transfer power from the engine to the wheels. Energy supply New Energy Vehicle (Electric Vehicle) Charging Port: Electric vehicles rely on charging piles for charging, usually equipped with standard alternating current (AC) or direct current (DC) charging ports.Charging equipment: such as on-board chargers, external fast chargers, etc. The charging process of EVs is more complicated compared to refueling, and the charging time depends on the charging power and battery capacity.Fuel VehicleFuel Tank: Fuel vehicles store gasoline or diesel fuel through the fuel tank, usually the refueling process is faster, the fuel tank has a larger capacity and can usually be refueled to completion.Refueling system: Includes fuel gun, fuel gauge, fuel pipe and other equipment used to deliver fuel to the fuel tank in the car. Drive System New Energy Vehicle (Electric Vehicle) Electric motor drive: the electric motor drives the wheels directly, reducing the need for complex mechanical transmission systems. Some EVs are all-wheel drive (AWD), driving the front and rear wheels separately via front and rear electric motors; while others are rear or front drive.Efficient Power Distribution: The instantaneous torque output of the electric motor can be precisely controlled and distributed by an intelligent electronic system. Fuel-Efficient Vehicles Internal Combustion Engine Drive: The internal combustion engine transmits power to the wheels through a series of components such as clutches, transmissions, driveshafts, and differentials. There are usually different types of drive such as front-wheel drive, rear-wheel drive and four-wheel drive (4WD).Differential: Used to regulate the speed difference between the wheels on both sides, especially when cornering. Suspension and Body New Energy Vehicle (Electric Vehicle) Body design: Since the powertrain of an EV is more simple, the body design usually focuses more on space optimization. Since the battery pack is usually installed at the bottom of the chassis, the center of gravity of EVs is lower, which helps improve handling.Suspension: The suspension of an EV is usually designed to be more refined to support the heavier battery pack. Some EVs have independent suspension designs to improve comfort and handling. Fuel Vehicles Body Design: Traditional fuel vehicles have a large engine and drivetrain that takes up a lot of space, and the body design usually focuses on reducing air resistance, improving comfort, and so on.Suspension system: Fuel vehicles also have diverse suspension systems. Depending on the model, independent or non-independent suspension may be used to balance cost, comfort and handling performance. Air Conditioning and Heating Systems New Energy Vehicles (Electric Vehicles) Electrically Driven Air Conditioning Systems: The air conditioning systems in EVs are usually powered by an electric compressor capable of providing cooling or heating while the vehicle is running, and usually do not rely on engine power.Heat pump technology: To improve energy efficiency, some high-efficiency electric vehicles use heat pump technology for interior heating, which is more energy efficient than traditional resistance heaters. Fuel-Efficient Vehicles Engine-driven air conditioning system: The air conditioning system in fuel vehicles is usually powered by an engine-driven compressor, which consumes a portion of the engine’s power.Warm air system: Fuel vehicles provide warm air to the interior through engine waste heat, usually using a hot water radiator to heat the air. Braking System New energy vehicles (electric vehicles) Regenerative braking system: Electric vehicles are usually equipped with a regenerative braking system, which improves energy efficiency by converting kinetic energy into electrical energy and recharging the battery through the electric motor working in reverse.Conventional Braking Systems: EVs are also equipped with conventional hydraulic braking systems (e.g. disc brakes) as a backup. Fuel Vehicles Traditional braking system: Fuel vehicles use a traditional hydraulic braking system, including brake discs and pads, which generate friction and consume energy during vehicle deceleration. Auxiliary System New Energy Vehicles (Electric Vehicles) Intelligent electronic control system:

An electric vehicle consists of an electric motor powered by a battery pack. The main advantage of electric vehicle components is that they have zero emissions and are environmentally friendly. They also do not consume any fossil fuels and therefore use sustainable forms of energy to power the car. The main components of an electric car are: Traction battery pack DC-DC converter Electric motor Power inverter Charging port Onboard Charger Controller Auxiliary Battery Thermal System (Cooling) Propagation Traction Battery Pack The traction battery pack is also known as the electric vehicle battery (EVB). It powers the electric motor of the electric vehicle. The battery acts as a power storage system. It stores energy in the form of DC current. The range will be higher as the kilowatts of the battery increase.Battery life and operation depend on its design. The lifetime of a traction battery pack is estimated at 200,000 miles. DC-DC Converter Traction battery packs provide a constant voltage. The DC-DC converter distributes the output power from the batteries to the required level. It also provides the voltage needed to charge the auxiliary battery. Electric Motors The electric traction motor is the main component of an electric vehicle. The motor converts electrical energy into kinetic energy. This energy makes the wheels rotate.The electric motor is the main component of an electric vehicle and it distinguishes an electric vehicle from a conventional vehicle. An important feature of the electric motor is the regenerative braking mechanism. This mechanism slows down the vehicle by converting its kinetic energy into another form and storing it for future use. There are basically two types of motors DC and AC motors. Power Inverter It converts the DC power from the battery to AC power. It also converts the AC current generated during regenerative braking into DC current. This is further used to charge the battery. The inverter can change the speed Charging port The charging port connects the electric vehicle to an external power source. It charges the battery pack. The charging port is sometimes located at the front or rear of the electric vehicle components. On-board charger The on-board charger is used to convert the AC power received from the charging port to DC power. The on-board charger is located and installed in the vehicle. It monitors various battery characteristics and controls the current flowing within the battery pack. Controller The power electronic controller determines the operation of the electric vehicle. It performs the regulation of electrical energy from the battery to the motor. The pedals set by the driver determine the speed of the vehicle and the frequency of voltage changes input to the motor. It also controls the torque generated. Auxiliary Battery The auxiliary battery is the source of electrical energy for electric vehicle accessories. In the absence of the main battery, the auxiliary battery will continue to charge the vehicle. It prevents the electrical system from being affected by the voltage drop generated during engine startup. Thermal system (cooling) The thermal management system is responsible for maintaining the operating temperature of the main electric vehicle (EV) components (e.g., motor, controller, etc.). It also functions during charging for optimal performance. It combines thermoelectric cooling, forced air cooling and liquid cooling. Transmission The transmission transfers mechanical power from the electric motor to the wheels. The advantage of electric vehicles is that they do not require a multi-gear transmission. Transmission efficiency should be high to avoid power loss.
