A fuel management system for vehicle fleet operators that can be integrated seamlessly with fleet management systems has been launched in the UK by Maximus, which claims to be the world's largest fleet management specialist.

FuelFocus makes use of radio-frequency technology. It gives a unique identity to each vehicle in the fleet, storing this on a small on-board computer and communications module. This module is linked to a sensor on the fuel filler, which detects when a filler nozzle is inserted.

The module then communicates via short-range RF link with software in the fuel dispenser, and will not allow the pump to operate unless authorisation is provided by the company's central database. Once it starts, details such as the vehicle's odometer reading are captured automatically - in some case together with vehicle fault codes captured via CANbus or J1708 output.

Theft prevention is said to be a key benefit. If the nozzle is removed, fuel flow immediately stops. If the nozzle is inserted in the tank of a vehicle without FuelFlow, the pump won't work. If the other vehicle does have FuelFlow equipment, the fuel will be allocated to it automatically.

Maximus makes very strong play of the integration features of the system. Because all records of all authorised vehicles are held centrally, vehicles can be fuelled at any location and records stay in sync. The company says it could be implemented as a stand-alone system, although some of these benefits would then be lost.

The dispensing unit can be set up in various ways. It can allow users to enter codes manually, or detect their identity via a keyfob-embedded proximity switch. There is even an option to actuate the system with ordinary credit cards; transactions can be processed either by the user-company internally or through the bank's clearing system.

The system is well-established in the US, where it is used by thousands of vehicles. Elements are also used in a scheme called FuelPass, allowing approved drivers to refuel at commercial filling stations. This is in use at 2,200 retail sites in half a dozen European countries.
