Specifications

• The Organisers provide these joulemeters for the duration of the event. A
security deposit may be required for the joulemeters.
• The joulemeters must be positioned so that their display can be easily
read from outside the vehicle.
• The joulemeters must be inaccessible to the Driver in his or her normal
driving position.
• In line with the technical specification of the joulemeters, the electric
currents must not exceed 50 amperes permanent and 150 amperes peak.
• Any types of batteries or Super Capacitor are permitted, subject to the
maximum voltage of 48 Volts.
• If a Lithium Polymer battery is used, the vehicle must be equipped with a
Battery Monitoring System (BMS) to control and protect the battery against
risk of fire.
• Batteries or Super Capacitor must be placed outside the drivers
compartment behind the bulkhead.
• The vehicles will go to the starting line with their batteries charged.
• On the starting line, Fuel Marshals will reset to zero the two joulemeters,
and then the vehicles will have access to the track to start their attempt
under the same distance and time conditions as specified for their
respective vehicle class.
• At the finish line, Fuel Marshals will read the two joulemeter displays.
• All Solar vehicles which complete a successful run will be classified.
Teams with a positive energy balance (i.e. more produced than
consumed) will be classified first, in order of ascending energy
consumption, followed by all vehicles with a negative energy consumption
(i.e. more consumed than produced), again in order of ascending energy
consumption.
• An additional on-board battery as defined in Article 71 is permitted. It must
not be connected to the electric circuit(s) involving any power train
components and must only be used to power safety related components
and those mentioned specifically in Article 71.
Article 81: ‘Battery Only’ Powered Vehicles (‘Plug-In’s’)
• The ‘Battery Only’ energy category is a new addition for the 2011 season.
• Competitors will be able to participate with both Prototype and
UrbanConcept vehicles in the new category.
• The drive train in the ‘Battery Only’ category is restricted to a maximum of
one electric storage device, electric motor(s), one control unit and the
required connections.
• Only Super Capacitors and Lithium Polymer batteries are permitted as
electric storage devices.
• If a Lithium Polymer battery is used, the vehicle must be equipped with a
Battery Monitoring System (BMS) to control and protect the battery against
risk of fire.
• Any type of electric storage device and on-board system is subject to the
maximum voltage of 48 Volts.
• The competitors must provide a description and a precise technical
drawing of their electrical drive train with the application.
• The entire drive train must be easily accessible for inspection and
measurements.
• Batteries or Super Capacitor must be placed outside the drivers
compartment behind the bulkhead.
