YAS Fuel Cells
Yorkshire Ambulance trust and Antares are worked together to demonstrate how much diesel can be saved by using fuel cells as an alternative to operating an engine whilst stationary and to avoid the use of trailing leads.
The system consists of three main parts: the auxiliary
battery, the fuel cell itself, and the Virtual Alternator system.
The fuel cell means that the RRVs can be left safe, secure and unattended, with their radio systems on but without the engine running. The Fuel Cell steps in as required to ensure that the batteries are always fully charged.
The Virtual alternator ensures that the maximum power is routed into the auxiliary battery whenever the vehicle is moving, thereby reducing fuel cell operation.
In Europe, legislation has already banned the use of primary vehicle engines being used when parked. The fuel cell offers a solution where the payload of batteries is impractical. A further advantage experienced was a reduction in the following : engine service intervals, premature engine wear and clogged DPFs.
This technique is currently used in Germany by the local police, as a mobile unit for the issue of speed tickets and other violations.
