✦ Synopsis

Two prototype EVs have been constructed as the product of the Finnish EV project. The vehicles have transistorized, microprocessor-controlled a.c. motors, on-board high frequency chargers, and pasted plate leadacid batteries located in thermally controlled containers. The performance of the vehicles has been measured using a dynamometer. The results agree with the laboratory measurements on the batteries. The on-road performance will be monitored with an on-board data logger. The main result of the tests performed so far is that the driving range in SAE J227aC cycle is almost equal to the range obtained at a 50 km h-l constant speed. This good performance in city driving is mainly due to the choice of the a.c. motor, exhibiting a high efficiency even at relatively low frequencies.

Skid-resistance of trafficked roads decreases due to polishing and can have a drastic consequence on the driver safety. There is a need to dispose of a laboratory test to forecast such variations on asphalt-mix specimens before the road construction. This paper is focused on the development of a pol
