Ubun2Tech – Battery-Powered Utility Trailer.
uYilo Kick Start funding from 2017 resulted in an off-road, battery-powered utility trailer, the ReLink. This project was a successful collaboration between Ubun2tech and eNtsa that, in just six months, resulted in the creation of a powered trailer to complement an electric quad bike.
As a proof of concept, with planned integration into a larger off-grid energy project encouraging improved self-sufficiency in rural communities, the ReLink trailer, powered by the latest generation smart 8kWh LiFeYPO4 (Lithium ion Yitrate Phosphate) battery pack, enables an electric-power quad bike to handle terrain and loads outside of the ability of a standard quad.
Where a quad bike pulling an unpowered trailer would face reduced range and struggle under load as the terrain conditions deteriorated, a powered trailer provides its own motion, radically reducing the load on the quad, limiting range impact and allowing for more work to be accomplished in tougher terrain.
It is this capability that the prototype Re-Link trailer will prove as it is initially utilised in the Tsitsikamma forestry area to assist in the clearing of alien vegetation.
While there is a physical connection between trailer and quad, this is rather for direction than propulsion. When the mechanical connection is disengaged, the electrical connection provides the relevant signals that the trailer will respond the same as previously.
