THE MOTOR

THE ELECTRIC BY OTK KART GROUP

E-Viper Electric Kart is equipped with an electric motor (brushless permanent magnet motor), developed and created specifically for karting, which guarantees a nominal power of 5.5 kW (peak of 12 kW) and an exceptional peak torque of 145 Nm at the wheels (45 Nm at the crankshaft).

Find out on the "Safety" page).

Icona più Practical advantages

Zeroing of CO2 emissions (and other gases harmful to humans and the environment) and noise emissions.
Access (depending on country) to tax breaks and bonuses for sustainable start-ups.
Streamlining of bureaucratic procedures for obtaining authorizations relating to the opening (and ordinary management) of outdoor and indoor kart tracks.
Reduced maintenance, thanks to the fewer moving mechanical parts with which they are equipped.

WEIGHT OPTIMIZATION

BATTERIES LASTING OVER 1H, WITH OPTIMIZED CHARGING TIMES

The electric motor of the E-Viper Kart is powered by 116 Ah NCM lithium batteries, a capacity at the top of the rental kart sector. This quality, together with the optimized weight of 197 kg, makes the E-Viper the electric rental kart with the best “capacity/weight” ratio available on the market, 0.589 Ah/kg. This means that for every kilogram of weight, the kart provides almost 0.589 Ampere/hour of battery capacity. Concretely, E-Viper kart offers the best energy storage efficiency and driving times of over an hour per charging cycle.

Regarding the charging station and the necessary timing:

7 kW three-phase chargers are required. Specifically supplied by OTK Kart Group, they communicate via CAN with the battery control unit, ensuring optimized charging times and greater longevity of the batteries themselves
The time ratio between charging and driving is 1 to 1. This means that 20 minutes of charging corresponds to approximately 20 minutes on the track.
