eRally is working with Europe’s largest independent provider of
EV battery systems to develop a battery for use in electric vehicles that
outlasts and outperforms current batteries. Latest EV battery technology is
based on lithium-ion.
eRally are looking beyond lithium-ion to
develop a battery based on emerging technologies that will outperform
current EV batteries.
Electric motors are rated on KW and voltage. Most electric
vehicles run at 48 volts. The motor being developed for the eRally car will
run at 400-500 volts and is based on latest purpose-built AC motor
technology. Higher voltage results in lower resistance and less heat which
results in higher performance. Additional liquid cooling is employed for
maximum performance on the rally stage.
power is essential with high performance electric motors. With full torque
available from zero rpm the controller software will limit the flow of
electricity to the motors to prevent damage to the drive-shafts or the car
simply spinning its tyres and digging a hole in the forest track.
Hydrogen fuel cells are used as a supplement or an alternative
to using batteries. The range of the car can be significantly increased by
deploying fuel cell technology, where Hydrogen is converted in the fuel cell
to electricity and fed either directly to the motors or to top up the
