Obiettivo To demonstrate the cost effectiveness and energy saving potential of the use of electric vehicles (type 900 TE 2 vans) by a public telephone company for deliveries and maintenance.The manufacture and testing of the test vehicle was completed in the project's first year, and by mid-1983 the remaining 9 vehicles had also been built. Monitoring of the vans under real conditions began in 1984 and ended in 1986.Improvements have been made to the initial design : the main regulator and auxiliary unit was modified to smooth acceleration, provide better speed control and eliminate electro-magnetic interference. In the topping-up gas connection loops the metal snap connectors of the battery modules were replaced by plastic connectors to prevent casual explosion of the monoblock. Flat batteries were replaced by more efficient tubular ones.During this period idle time was 30 days/year, this ratio is higher than the one for conventional vehicle (10 days). The weak point is the traction batteries system.Energy consumptiona) For short trips energy consumption varied considerably, from 200 Wh/km to1,300 Wh/km; it was less variable for trips over 20 km, ranging from 300 to 500 Wh/km.b) High electricity consumption was due to overcharging of the batteries.c) 38 % of vans (weighting 1,400-1,900 kg) consumed less than 500 Wh for routes of 20-40 km.d) Best results were consumption of 460 Wh/Km while the average was 650 Wh/Km; so the the nett primary balance is negative by about 30%.e) Improvements are expected thanks to an "intelligent battery charging device". The development of such a system, however, cannot be carried out until 1989-1990.The battery-charger (AMPHERORAMETER type) has been developped and tested of prototype level (1990)The charger-efficiencies has been revealed with good results for batteries and with small discharges (about 50%).The system has not been developped at industrial level.Ten 900 TE 2 vans derived from the conventional 900 T, manufactured and tested by Fiat were delivered to the telephone company. One "lab. van" contained monitoring equipment and one monitoring system was established to measure electricity consumption, nature of trip, distance, technical problems, idle time, battery life etc. Programma(i) ENG-ENALT 1C - Programme (EEC) of financial support for projects to exploit alternative energy sources, 1979-1984 Argomento(i) 1.9 - TRANSPORT Invito a presentare proposte Data not available Meccanismo di finanziamento DEM - Demonstration contracts Coordinatore Fiat Carrelli Elevatori SpA Contributo UE Nessun dato Indirizzo Via P.
