With sales of electric vehicles (EVs) already rising by 144 percent in 2019, the popularity of EVs will only continue to increase, but they haven’t always been racing ahead. Here, Simone Bruckner Managing Director of Cressall, looks at the history of EVs, and the developments that advanced them.

Oxford-based solar technology firm, Oxford PV, plans to volume manufacture the world’s most efficient solar panel by the end of 2020.

There would seem to be a world of difference between the current generation of advanced electric sports cars and the heavy industries where Leicester based electrical firm Cressall Resistors traditionally operates.

Cressall Resistors and Control Techniques collaborate on a project to produce a rugged braking system for pipe laying vessels.

Cressall Resistors has developed a new range of liquid cooled resistors for the braking systems of hybrid and all-electric vehicles. The new range, dubbed the EV series, converts excess electricity that is not needed for recharging the vehicle’s battery into heat that can be dissipated safely. They make genuine regenerative braking in electric cars a possibility by providing a method to dissipate excess braking energy as heat, via the water system.

In any application, dynamic brake resistors (DBRs) have to be reliable. However, this is particularly true in a high-intensity manufacturing environment where a breakdown could prove extremely expensive in lost production. In the sixty years since it was established, Street Crane has become a trusted volume manufacturer of overhead cranes and hoists for exactly these kinds of applications, and takes great care when specifying DBRs for its products
