In June 2023, the hybrid drive laboratory was launched, made up of an electric engine roller dynamometer and a piston engine roller dynamometer.

At Łukasiewicz Institute of Aviation it is the first test station for hybrid drives for aviation applications that meets R&D needs of the aviation market.

Hybrid drive roller dynamometer

The station is equipped with a battery simulator with the following main parameters:

• simulator power supply 3×400 V AC,
• continuous power 80 kW,
• instantaneous power 120 kW (60 sec.),
• output voltage adjustable 24-800V DC,
• rated current +/- (bidirectional) 267 A,
• peak current + / – (bidirectional) 400 A,
• rapid prototyping of the required energy storage capacity
  and conducting long-term tests with DC voltage.

Liquid cooling of motors/inverters

• Water cooler #1 – maximum heat capacity 5 kW,
• Water cooler #2 – maximum heat capacity 10 kW,
• Water cooler # 3 – maximum heat capacity 30 kW.

Parameters of the tested generator in serial hybrid setup (internal combustion engine + energy storage charging generator)

• Maximum electrical power returned to the grid – 80 kW (peak 120 kW – – battery simulator constraints,
• maximum torque 100 Nm, maximum speed 12,000 rpm/ min or maximum torque 500 Nm, maximum speed 7,000 rpm/ min (depending on the torque meter installed).

Parameters of the tested electric motor in parallel hybrid setup (internal combustion engine + load driving electric motor)

• The maximum total power of a hybrid drive: 200 kW,
• The maximum power of an electric motor powered by a battery simulator: 80 kW,
• Maximum speed 6000 rpm/ min,
• Maximum torque 700 Nm,
• The drive is loaded with an eddy current brake.
