E-cart

from Wikipedia, the free encyclopedia

E-kart stands for electrically powered karts . They are used in recreational sports, but for the first time since 2011 also at racing events such as B. the 24h race in Cologne, where they compete against petrol karts. However , they are not allowed to be used on public roads .

drive

The electric drive has also found its way into karting. A possible restriction of the driving dynamics due to the additional weight of the batteries carried is counteracted by separating the drive wheels, relocating the battery pack to the center of the kart, changing the overrun and energy recovery . With 6 kW (around 8 PS) a speed of over 100 km / h is possible, but on kart tracks the speed is electronically reduced to 50 km / h.

power supply

Batteries of various types, for example on the basis of lithium iron phosphate , are used as the energy source , with which today up to 60 minutes of operating time (with approximately the same charging time) are possible. They are monitored by a battery management system (BMS). This includes temperature monitoring with cooling against overheating. Vehicles with conventional lead batteries, which are characterized by shorter operating times, are also currently on the market.

The accumulators increase the weight of the kart considerably, it weighs around 200 kg. This results in a lower power- to- weight ratio , and the steering forces and tire wear also increase. Some manufacturers therefore do without a rigid drive shaft to counteract this, and therefore install a differential or one motor per rear wheel.

Other features of the electric drive

The vehicle setup can be adapted to the respective route using programmable controllers . There is also a reverse mode. By remote access, karts can be braked or stopped individually or together, for example to avoid danger. The emission-free vehicles make use in heated halls easier.

The current world record for acceleration from 0 to 100 km / h with a kart was achieved in 2.635 seconds with an electric kart.

There has been a go-kart track in Munich since 2011, in which only electric vehicles are used. According to the operator, the lower operating costs outweigh the higher investment of around 10,000 euros (instead of three to four thousand euros for a gasoline-powered vehicle). The quieter vehicles appeal to new groups of customers with women and children.
