This article presents the results of work related to the power supply system for 10kW electric, rental go-kart. The research took into account a few types of battery cells. For the case study, the best option was chosen taking into account the restrictions included in the multicriteria analysis for further application. Chosen BLDC motor and battery type were tested on test stands and simulated in MATLAB/Simulink. Simulation model allowed to compare the characteristics from test stands and simulation and next tune the model. Minimum capacity of the batteries had to allow for at least 20 minutes of drive. Chosen elements: electric motor, motor controller, battery cells, BMS allowed to build the first prototype. Tests in real conditions showed the difference between simulation and research system. We could notice what to improve to tune the simulation model and the kart power supply system.

This article presents the results of work related to the design, analysis, and manufacturing of the shaft for an electric go-kart. Works considered the stiffness of the shaft for various conditions affecting the vehicle while driving. In the previous stage of the project, the electric motor and gear transmission were selected. The main goal of this case study was to design the shaft for 10 kW electric go-kart. The rear driving axle of the go-kart is not equipped with a differential. The equal rotational speed of two rear wheels causes that occurs skidding and greater forces acting on the vehicle and driver when cornering. We were considering two types of the shaft – full and drilled. The first one provides greater stiffness, the second one is “softer”. The analysis allowed for the selection of a more appropriate shaft, and then for its manufacture and assembly in the vehicle.

Today electric vehicles are becoming increasingly popular in our lives. In motorsport, however, they are not as widely used. Formula E, which was created to boost electric motorsport, is not enough to popularize it. Every driver wanting to advance to F1 (highest rank racing series) has to start from karting between the ages of 5 and 8. But today go-karts are only powered by combustion engines. In order to provide young drivers with the possibility of racing small electric vehicles, the so called eKarts, combustion engines have to be replaced with electric motors. EKarts should offer similar performance to combustion engine go-karts. Therefore to determine the required power of the electric motors and the capacity of the batteries in eKarts for different age categories, the technical parameters of the different age categories of combustion engine racing go-karts were analyzed in this paper. In this paper it was proved that present Li-Ion battery technology makes it possible to construct eKarts for children’s and junior categories. With the current technology, it is not possible to create an eKart for senior categories (15 and over) in line with the current regulations for go-karts.

The article presents the prototype of the original telemetric system developed as a part of Warsaw University of Technology Rector's Grant by Science Club of Electrical Engineering in Transport Systems (KNEST) together with the Faculty of Transport. The system was designed for remote monitoring and recording of electric vehicle’s operating parameters. Under the project electric go-kart was a technology demonstrator for which velocity, current, voltage, temperature and GPS coordinates were recorded. Data are transferred in real-time, what allows to monitor all parameters of the electric vehicle on-line. The article describes functional requirements for the developed system and the elements used, including sensors of signals. The authors present steps of transfer of data acquired from the vehicle until their visualization at the remote computer through the developed application. The advantages of the system are long range wireless connectivity, low price and wide upgrade possibilities. The tests performed have shown the correct functioning of the system and its compliance with the assumptions.

W artykule przedstawiono prototyp systemu telemetrycznego wykonany w ramach Grantu Rektora Politechniki Warszawskiej przez Koło Naukowe Elektrotechniki w Systemach Transportowych (KNEST) działające przy Wydziale Transportu. System jest przeznaczony do zdalnego monitorowania i rejestracji parametrów eksploatacyjnych pojazdów elektrycznych. W ramach projektu demonstratorem technologii był gokart elektryczny, dla którego rejestrowano prędkość, prąd, napięcie, temperaturę i współrzędne GPS. Dane wysyłane są w czasie rzeczywistym, co umożliwia monitorowanie wszystkich parametrów pojazdu elektrycznego w trybie online. Artykuł zawiera opis wymagań funkcjonalnych dla stworzonego systemu oraz użyte elementy podczas realizacji Grantu m.in. czujniki sygnałów. Autorzy przedstawiają etapy transmisji danych zbieranych z pojazdu do momentu ich wizualizacji na komputerze zdalnym przy pomocy autorskiej aplikacji.

A method for a sizing of an electromechanical battery for electrical go-kart was presented in the paper. The main goal of this research was to replace the internal combustion (IC) engine by an electric drive system taking into account the traction properties, on the one hand and the duration of operation on a single charge and the number of the battery life cycles on the other. The proposed method permits an entire depreciation of the price of the vehicle before the degradation of the battery occurs. The results of the study have been used to adjust the source for electric go-karts that will be mass produced.
