One of the key technologies in electric vehicles is the battery. Rechargeable lithium-ion batteries are the primary source of energy storage, and they provide power to propel the vehicle. The advancement of battery technologies in electric vehicles enhances range, energy density, charging speed, lifespan, and performance.
2. Electric Motors
There are several types of electric motors, such as DC series motors, brushless direct current (BLDC), permanent magnet synchronous motors (PMSM), AC induction motors, and switched reluctance motors (SRMs). Among them, AC induction motors and brushless DC motors are the most used motors because of their high efficiency, reliability, and longer life span.
The other significant key technology in electric vehicles is the electric motor. It is an integral part of electric vehicles, as without it, EVs would not run. It converts electrical energy into mechanical energy. Electric motors are the heart of EVs, and electric vehicles offer several advantages, like lower maintenance costs, zero emissions, and noiseless operation over gasoline vehicles. The light-weight electric motors are helpful to produce instant torque, which results in fast acceleration.
3. Regenerative Braking System
Regenerative braking is another key technology in electric vehicles, and it stores energy that is lost during braking. This system converts kinetic energy into electrical energy, which is stored in the battery for later use. Regenerative braking improves overall energy efficiency and extends the driving range of the vehicle.
4. Power Electronics
Power electronics is the central nervous system of all electric vehicles. The main components of power electronics are inverters, DC-DC converters, and chargers, which control the flow of electricity between the battery, motor, and other vehicle systems. The key technologies in electric vehicles play a vital role in optimising efficiency, managing power delivery, and ensuring the smooth operation of the electric drivetrain.
5. Battery Management System
Battery management systems is another remarkable key technology in electric vehicles. It plays a crucial role in the safety of the battery pack. It manages the state of health (SoH) and state of charge (SoH) of the battery pack and monitors current, voltage, and temperature across cells, ensuring the cells work within safe parameters. The battery management system ensures optimal battery operation, protects against overheating and overcharging, and avoids damage to the battery. Its chief purpose is to keep the batteries safe and reliable, enhancing their lifespan.
6. Thermal Management System
Thermal management system is one of the most noteworthy key technologies in electric vehicles, as it plays a significant role in optimising the efficiency, performance, and safety of electronic vehicles. It contributes to widespread adoption and acceptance as a sustainable transportation solution. A Thermal Management System actively regulates the temperature of the battery cells to prevent overheating during charging or discharging. In addition, it regulates the temperature of the motor by circulating coolant into the motor housing and controls the climate inside the cabin to provide passenger comfort. TMS contributes to maximising the vehicle’s driving range on a single charge.
HVAC (Heating, Ventilation, and Air Conditioning) systems regulate cabin temperature and humidity, ensuring a pleasant driving experience regardless of external weather conditions.
7. Vehicle-to-Grid (V2G) Technology
Another significant key technology in electric vehicles is vehicle-to-grid.
It is a two-way communication system that enables electric vehicles to interact with the electric grid, helping them to draw energy from the grid for charging and supply energy back to the grid whenever needed. It is a bidirectional energy flow between EVs and the grid that facilitates electric vehicles to serve as mobile energy storage units.
This technology improves grid stability and reliability. V2G technology is helpful to provide backup power during emergencies or power outages. It supports the integration of intermittent renewable energy sources into the grid. V2G technology prevents grid overloads. It is a promising innovation in the field of electric vehicles and renewable energy integration that offers a pathway towards a more efficient and resilient electric grid.
8. Advanced Driver Assistance System
Advanced Driver Assistance System is a set of key technologies in electric vehicles. It assists drivers in operating vehicles more safely and efficiently. It enhances driver awareness, improves vehicle control, and reduces collisions. The components of the Advanced Driver Assistance System include a collision avoidance system, lane departure warning, adaptive cruise control, blind spot detection, pedestrian detection, traffic sign recognition, and automatic parking assistance.
9. Wireless Charging Technology
Wireless charging is another key technology in electric vehicles which enables the charging of EVs without the need for physical cables. A charging pad is installed on the ground, and it contains a transmitter coil that generates an alternating magnetic field when connected to a power source. An electric vehicle has a receiver coil that is mounted on the underside of the vehicle. When the electric vehicle is parked over the charging pad, the energy transfer from the charging pad to the vehicle occurs without physical cables.
It is becoming increasingly popular as it eliminates the risk of electric shock, reduces wear and tear on charging connectors, and enhances convenience for EV owners.
10. Digital Infotainment systems
A digital infotainment system is one of the key technologies in electric vehicles that enhance the driving experience, as it refers to the integrated multimedia interface that provides entertainment, navigation, and communication. It generally consists of a touchscreen display, voice recognition, smartphone integration, multimedia playback, etc. It offers various connectivity options, such as Bluetooth and WiFi. The infotainment system allows users to play multimedia content from various sources like FM radio, digital radio, SD cards, USB drives, etc. The voice recognition function helps the user control various functions through voice commands.
11. Public Charging Infrastructure
One of the significant key technologies in electric vehicles, which undergoes several installations, is public charging infrastructure. The availability of public charging infrastructure is the backbone of the electric vehicle industry, as it allows drivers to enjoy long journeys without compromise.
