W artykule przedstawiono projekt, wykonanie i sterowanie systemem Stop&Go w napędzie Mild Hybrid, który wykorzystuje superkondensatory i rozrusznik z magnesami trwałymi. Przeprowadzonych zostało wiele badań i testów w celu ustalenia rzeczywistych i reprezentatywnych cykli jezdnych w aglomeracji śląskiej dla miast Gliwice i Zabrze. Badania drogowe umożliwiły przeprowadzenie analizy płynności ruchu w miastach i wyznaczenie procentowego udziału poszczególnych mikro-etapów ruchu (wybrane etapy przyspieszania, jazdy ze stałą prędkością, hamowania i postoju). Przeprowadzono badania przydatności wykorzystania superkondensatorów jako zasobnika energii elektrycznej potrzebnej do wykonania rozruchu silnika spalinowego. Zastosowanie supekondensatorów poprawia wskaźniki ekonomiczne systemu Stop&Go. Superkondensator ma 1000 razy większą trwałość niż adekwatny akumulator PbPbO2 przy około 40-krotnie mniejszej masie. Zaprojektowano rozrusznik z magnesami trwałymi NeFeB umieszczonymi w stojanie rozrusznika zamiast uzwojeń miedzianych. Modernizacja rozrusznika jest niezbędna ze względu na częstsze niż normalnie rozruchy silnika spalinowego. Projekt systemu Stop&Go został przeprowadzony na bazie samochodu Fiat Palio z napędem Mild Hybrid.

Article describes design, develop and control of the Stop&Go system in Mild Hybrid Drive using supercondensator and starter with permanent magnets. Many researches and tests were done to determine real and then representative cycles of drive in Silesian agglomeration in Gliwice and Zabrze. Road researches enabled carrying out analysis of fluidity of traffic in cities and setting a percentage shares of movement micro stages (selected accelerations, driving with constant speed, braking and stopover). Researches of usefulness of supercondensators’ system as an energy source in process of starting an internal combustion engine were done. Usage of supercondensators as an energy source of starting led to improvement of economic indicators of the Stop & Go system. Supercondensator has a 1000 times bigger durability than PbPbO2 battery with around 40 times smaller mass. A starter with permanent magnets NeFeB in stator instead of induction winding was designed. A modernization of the starter is necessary because of frequent than normal start-up cycles of the ICE. A design of Stop & Go system was carried out of the basis of Fiat Palio with Mild Hybrid drive.

W artykule opisano początkowy etap konstrukcji napędu hybrydowego samochodu o strukturze Mild Hybryd. System ten pozwoli m.in. na automatyczne wyłączanie silnika spalinowego podczas postoju (w korku, na czerwonym świetle) a następnie ponowne szybkie załączenie. Zaprezentowano wybrane wyniki badań procentowych udziałów podstawowych faz cykli ruchu jazd testowych miastach śląska. Pomiary przeprowadzano na trasie Gliwice - Zabrze, w Zabrzu oraz Gliwicach. Przedstawiono badania superkondensatora w procesie rozruchu silnika spalinowego.

The paper describes initial stages of Mild Hybrid drive system design. This type of drive uses a traditional electric unit consisting of a battery, a starter and an alternator. This system, appropriately adapted, for instance by increasing its overall rated power and supplementing it with novel energy control procedures, can operate in a manner similar to hybrid car drives. Mild Hybrid system utilises standard components used in cars - i.e. starter and alternator. A supercapacitor will be introduced as a new component. Its role is to operate as energy accumulator for IC engine start-ups. A traditional car battery will also assume a new function, that of heating IC engine. Automobile Stop & Go System makes it possible to switch off the IC engine automatically when a vehicle stops (e.g. at red light or in traffic hold-ups) and then to switch it on quickly again. This results in decreasing the fuel consumption and carbon dioxide emission, particularly in towns. Within the framework of this study, there were taken the road measurements whose aim was to determine the real driving cycles. The results of supercapacitor performance during IC engine start-ups are presented in the paper. Several tens of IC engines start-ups were conducted, with the starter supplied from a traditional standard lead-acid battery (Centra Futura 055 290, C20=55Ah); next, similar tests were run using the supercapacitor (MAXWELL BPAK 15V 58F). The energy consumption at start-up and the start-up time were calculated.

This action makes it possible to decrease fuel consumption and carbon dioxide emission, particularly in towns. Results of supercapacitor performance during IC engine start-ups are presented in this paper. Energy consumption at start-up has been calculated together with start-up time. Magnetti Marelli-Denso E80E car starter used in Fiat Palio Weekend has been used in tests, this starter is rated at 12 V 1,0 kW. Several tens of IC engines start-ups were conducted, with starter supplied from traditional standard lead-acid battery (Centra Futura 055 290, C20=55Ah); next, similar tests were run using supercapacitor (MAXWELL BPAK 15V 58F). Within the framework of this study, there have been done a range of the road measurements whose aim was to determine the real driving cycles. Route Gliwice – Zabrze, Route Zabrze, Route Gliwice –city centre, Route Gliwice. The biggest standing share has been obtained for the route 3 – Gliwice centre (37,9% of the percentage value of the drive time). The subject of this paper is in agreement with carbon dioxide emission standards set by European Union states, since special attention is paid by EU regulations to car transport activities (Kyoto protocol based on UNFCCC, European Climate Change Programme and Intelligent Energy Europe programs.
