Research on the Possibility of Using a Hybrid Electric Vehicle Powertrain in V2X Applications

The article presents the results of an experimental analysis of the possibility of gaining electricity to external loads from the Hybrid Electric Vehicle powertrain. The tests were carried out on a vehicle with a series-parallel hybrid drive system, where a mode of charging a battery at standstill is possible. The analysis was aimed at determining the feasibility of using a hybrid vehicle as a stationary source of electricity in the Vehicle-to-Load, Vehicle-to-Home, and in emergency applications even as Vehicle-to-Grid application. The tests consisted in loading the High-Voltage battery of the car with an external load of several different values. In the first approach, receivers intended for 230V AC power were used, but also tolerant to DC power supply with a voltage in the range of 200-250V. The operating parameters of the vehicle's hybrid drive system were recorded, as well as the amount of energy supplied to the receivers from the system. Particular attention was paid to the behavior of the cooling system of the vehicle systems. The analysis showed that without interfering with the operation of the vehicle's electronic controllers, it is possible to deliver energy to an external energy receiver. In the analyzed range of load changes, no malfunction of the hybrid system was recorded. As a result of the work carried out, the directions for further work on the system were defined.
