ACTCSS - a radical solution

Inspired by the designs of Min Chen of Loughborough University, the Active Control of Trolleybus Current Collector System (ACTCCS) is a radical re-think of trolleybus technology.

Twin wires
With up to 80% of the overhead of a Dynamic charging trolleybus route and complex crossings and switches all being avoided, the opportunity exists to create an innovative new system that further avoids accusations of 'the visual intrusion of an old technology' while creating an operationally sophisticated way of powering on-the-move.

The ACTCSS system is designed to apply current guidance, materials and dynamic engineering practice to the need to provide in-motion charging to update trolleybus technology to fit within modern urban environments and provide optimum efficency and economic effectiveness for the electrification of buses. A single boom, fitted with a butterfly guide, engages a twin conductor single line using an ultra-wideband real-time locating system and laser-trackers, both on the tbus and the overhead, that ensure accurate re-wiring.

  100% electric buses powered from overhead wiring and having no on-board fuel are the most energy efficient buses yet built. IMC versions with batteries are more efficient than any other alternative fuel solutions.
  a trolleybus consumes 50% less energy than a comparable diesel (iea)
  trolleybus operational costs are 50% that of light rail systems (iea)
  proven technology, existing manufacturing base
  consistent customer appreciation, potential for car/bus mode change
  operating and capital costs comparable with diesel bus
  total life cost advantages (but dependant on battery costs)
  recuperation of energy inherently provided for, using batteries and supercapacitors onboard and in substations
  in-motion charging established with sophisticated energy management and shown on route extensions throughout the world
  IMC trolleybuses use smaller batteries with no opportunity charging delays
  battery technology unlikely to achieve necessary ability to replace diesels on high capacity routes (zeeus)
  battery charging infrastructure and battery replacement costs prohibitive
  opportunity battery charging logistics problematic in large systems, likely to cause queuing delays at charger points
  overnight battery charging not economic on >16hr service time without additional vehicles/staff (of the order of an 1/6 increase)
  avoids road junction overhead complexity but maintains strong route identity
  could use reduced overhead on >20% of any route, saving capital and maintenance
  potential for less dewirements and less arching
