The electric vehicle industry is accelerating at a rapid rate with the emergence of new technologies. Following growing environmental concerns, Europe is leading the electric vehicle truck market striving to make all vehicles hybrid or electric to reach the European Union’s sustainable goals. In addition, environmentally conscious drivers are contributing to unprecedented numbers of vehicles becoming increasingly reliant on electrical power.

Efficient and reliable

To create a customer experience which enables reliable and efficient driving, EV manufacturers must invest in the most innovative technologies to enable electric power to reach its full potential and continue to meet rising expectations.

Critical to electric vehicle performance is the ability of electric power to effectively service all functions of the vehicle from reliable and safe driving to on-board entertainment. To transmit and protect power within the vehicle, electric cables must be protected and capable of withstanding a variety of environmental pressures. Any loss of connectivity during a journey could result in the interruption of driving, increasing risks on the road.

With many driving conditions present throughout a journey, it is a challenge for electric vehicles to hold high-voltage power without interruption, with a number of harsh environments potentially experienced. To enable demanding applications throughout the vehicle, electric vehicles rely on high-voltage connectivity solutions to move power to and from the battery and between various systems throughout the vehicle. Managing and keeping these cables in place over the life of the vehicle and through a range of driving conditions is critical.

High-voltage connectivity solutions must stand up to wide temperature fluctuations, vibration and mechanical impact to ensure high-voltage cables and components running through the vehicle are protected. High performance electrical insulation, EMI protection and fluid resistance are also important properties for this critical application.

Maximising power

Electric vehicles use high-voltage cables to maximise the power potential of vehicles. These cables are designed to be resilient to various conditions. For example, RADOX® high-voltage cables from HUBER+SUHNER are ready for any environment and can be used in temperatures from -40°C to +150°C at a lifetime of 3,000 hours without dissipation of the electrical properties. The RADOX® single and multi-core cables have an ultra-small bending radius that ensures an agile performance in the smallest cable cross-sections enabling electric vehicles to maintain power and continue driving.

Optimum protection is essential to minimise the risk of any damage that may lead to a loss in electrical performance. The HUBER+SUHNER RADOX® EV-C cable feed-through (cable gland) has proven its ability to protect cables against environmental factors as it acts as a barrier to moisture and debris by providing a reliable connection and seal. It has a high shock and vibration resistance for the most demanding heavy-duty applications such as commercial vehicles and special vehicles. As a wire-to-device system, it connects high-voltage devices within vehicles in a compact and flexible way to meet limited space requirements. It also offers 360-degree EMC shielding and environmental protection.

Many electric vehicles on the road today are designed with the most innovative solutions to provide the best performance which meets the demands of vehicles. With many factors to consider, the high-voltage connectivity solutions should be designed to provide reliable power to ensure electric vehicles have a smooth and safe journey.
