Performance analysis of an onboard PV system on a demonstrator light
commercial vehicle
Abstract
We present an analysis of the performance data of a monitored PV
system onboard a light commercial electric vehicle during parking and
driving conditions. The PV system’s nominal power is 2180
WP with flat silicon modules on the vehicle’s roof,
rear, left, and right sides, as well as other electronic components
needed to charge the vehicle’s high-voltage (HV) battery. The analysis
indicated that after 488.92 hours of operation, the modules mounted on
the vehicle roof produced 133.32 kWh of electricity during parking
compared to 15.4, 30.67, and 22.99 kWh for the modules mounted on the
rear, left, and right sides, respectively. During the trips, after 31.99
hours of operation, 6.12, 0.68, 1.08, and 1.86 kWh of electricity were
produced by the modules on the roof, rear, left, and right sides,
respectively. The overall system efficiency was in the 60-65 % range.
The aggregated usable electricity reaching the HV battery after multiple
conversion stages generated by the system at the two parking locations
was 129.39 kWh. PV electricity generated at the two parking locations
enabled a range extension of approximately 530 km, which is 30% of the
total distance driven during the measurement period between April and
July 2021.
