Specifications

• Competitors are required to provide the main characteristics of the battery
in their technical documentation: maximum voltage that can be supplied,
capacity in ampere-hours (i.e. the quantity of electricity that the battery can
theoretically provide when new), dimensions and weight. The on-board
battery is not allowed to power compressors, blowers, engine cooling
systems, motors, etc. It may however be used to power a ventilation/cooling
fan for the driver.
• Competitors must provide the Organisers with a precise description and
technical drawing of the vehicle’s electrical circuitry.
The Organisers reserve the right to request additional information
from Teams using high-capacity batteries.
• The Organisers reserve the right to request Teams to install one joulemeter,
intended to measure the quantity of energy provided by the battery. If this
amount of energy exceeds the power typically required to operate the
starter motor, horn and safety devices the competitor will be disqualified.
• Batteries must be installed outside of the driver’s compartment behind a
bulk head.
• The following devices may be powered by additional batteries provided they
use built-in batteries: radio communication system, GPS system, data
loggers excluding engine management units, driver ventilators.
• If a Lithium Polymer battery is used, a Battery Monitoring System (BMS)
must be installed to control and protect the battery against risk of fire.
