Abstrakt
Fossil fuel deposits are constrained in the world. Various alternative energy sources
are introduced in vehicles to limit the depletion of fossil fuel reserves and to reduce environmental
pollution. One of the alternative energy sources is electricity. Th
e use of electric automobiles has
begun in the Baltic States too, yet accurate performance parameters of the automobiles, which
could sometimes differ from the technical characteristics specified, are not always known. Road
testing an electric automobile w
as performed using a data logger that recorded the battery’s
voltage, current, temperature and the automobile’s speed. These parameters allowed computing
changes in the electric automobile’s power output under various driving regimes, e.g. acceleration
or
braking. Road testing the electric automobile was done under two driving regimes
–
urban and
non

on a certain route. The experiment represented a full cycle road test, with the batteries
fully charged, that lasted until the batteries were discharge
d to a minimum level, which was
limited by the battery management system (BMS). The experiment identified the maximum
current as well as the effectiveness of the regenerative braking system.
