How to improve connectivity, power and electric motor performance in commercial vehicles

4th June 2024  |  Electric vehicle

Enhancing EV performance is crucial for making them a viable alternative to combustion engine vehicles in commercial applications. This necessity stems from the commercial sector’s unique demands, including prolonged operational hours and the need for robust, energy-efficient systems that can handle intense daily usage.

There are three key performance areas that are critical for maximising commercial EV performance: connectivity, which enables real-time communication with infrastructure and other vehicles; power management, crucial for balancing vehicle performance with energy efficiency; and electric motor efficiency, which affects range, responsiveness and overall vehicle dynamics.

In this article, we go over each of these in detail, and unpack the ways in which they can be improved to enhance overall EV performance.

Understanding the key performance criteria for commercial vehicles

  • Connectivity: In the context of EVs, connectivity encompasses the vehicle’s ability to communicate with external systems and internal components. This includes vehicle-to-infrastructure (V2X) and vehicle-to-vehicle (V2V) communications, telematics and real-time data exchange, which are essential for enhancing operational efficiency and safety.
  • Power: Power management is crucial to balance the ability for commercial vehicles to perform their role successfully whilst maintaining operational efficiency. This includes the efficiency of power conversion, distribution and the minimisation of energy losses throughout the vehicle’s electrical systems.
  • Motor: The motor is the heart of any electric vehicle, converting electrical energy into mechanical power. Improvements in motor efficiency directly influence the vehicle’s range, torque, responsiveness and overall performance. These factors are crucial for commercial applications where reliability and battery lifespan are paramount.

Specific solutions for optimising commercial EV performance

After understanding the crucial aspects that influence EV performance, we can explore targeted solutions that specifically enhance connectivity, power and motor efficiency in commercial electric vehicles.

Optimising electric motor design

Advanced motor technologies: Utilising technologies such as permanent magnet synchronous motors (PMSMs) and switched reluctance motors (SRMs) can significantly enhance motor efficiency. These motors are known for their superior torque control and energy efficiency, making them ideal for heavy-duty applications.

Thermal management for maximised energy density: Avoiding high temperatures is key to maximising the energy density and torque of electric motors. Using systems like water cooling help maintain operational temperatures to maximise energy density. This is particularly beneficial in commercial vehicles where constant usage over long periods can result in a build-up of high temperatures.

Enhancing battery and charging systems

Fast charging infrastructure: Implementing fast charging technologies is crucial for reducing downtime in commercial EV operations. Systems capable of rapid DC charging can significantly shorten charging periods, improving vehicle availability and operational efficiency.

Sophisticated battery management systems (BMS): A robust BMS ensures optimal performance and longevity of the battery by managing its charge and discharge processes and monitoring its health. This is essential for maintaining battery efficiency and extending its service life.

Advanced connectivity features

Integration of V2X technologies: V2X communication enables vehicles to interact with traffic systems and other vehicles to enhance road safety and operational efficiency. This technology supports advanced driver-assistance systems (ADAS) by providing essential data for route and speed management.

Telematics and fleet management systems: Employing telematics allows for real-time monitoring and management of vehicle performance and maintenance. This helps fleet operators optimise routes, reduce costs and improve vehicle uptime.

Reliable and efficient power transmission

High-performance connectors: Ensuring efficient power transmission within the vehicle requires reliable connectors. TE Connectivity’s IPT-HD High-Voltage Connectors and PowerTube Connectors, for instance, are designed to handle high currents and voltages efficiently while withstanding environmental stressors typical in commercial vehicle operations.

Optimised wiring harness designs: Enhancing the wiring harness with high-quality materials and protective sheathing helps minimise electrical resistance and physical degradation. Proper routing and shielding of wires also reduce potential failures and maintenance costs.
