Electrification in flux

With electrification of commercial vehicles increasing in popularity and the introduction of permanent ePTOs (electric power take-offs) and even electrical outlets, the way in which we use mobile work equipment is undergoing a fundamental change. These developments demand innovative solutions from vehicle manufacturers – solutions that can guarantee a reliable and safe energy supply.

With continuous innovation and the pursuit of higher safety standards, Bucher Hydraulics is able to demonstrate that efficiency and safety can be aligned.

Short-circuit protection for electric vehicles

Modern power electronics in electric vehicles always have highly effective short-circuit protection to protect sensitive semiconductor elements from damage. In contrast to stationary systems where conventional fuses are used to interrupt the flow of power in the event of overload, they are not needed in vehicles. In vehicle electronics, the flow of power is automatically interrupted in milliseconds when a short-circuit is detected, which is a quicker response than that produced by a conventional fuse. This rapid response thus protects the wiring and connected loads, contributing to the reliability and longevity of the vehicle.

Sophisticated protective measures for electrical outlets in commercial vehicles

Electrical outlets in commercial vehicles expand their functional capabilities considerably and enable operation of devices such as tools, battery chargers, coolers, heaters, and lighting equipment. In addition, they also allow for use of high-performance compressors, helping to expand vehicle deployability. The installation of electrical outlets in commercial vehicles is subject to certain safety requirements, and in order to minimize risks, especially in the event of access by untrained personnel, sophisticated protective measures are required.

Safe electrical outlets in commercial vehicles

Bucher Hydraulics has been working on development of an innovative solution that meets the new requirements. These safe outlets are fitted with high-impedance IMDs that quickly detect insulation faults and interrupt the circuit before hazards can arise.

These advanced safety features mean that the vehicle's traction system remains unaffected by the effects of an insulation or short-circuit fault. At the same time, user safety is also ensured even when multi-outlets without their own fault-current circuit breakers are used.

The Bucher Hydraulics approach will help to ensure that outlet solutions are not just functional but extremely safe and will become an essential component of modern-day commercial vehicles.
