Abstract: In order to ensure a good power supply of a vehicle, different energy sources - from classical to new- are putted together, forming automotive hybrid systems.
From batteries to supercapacitors, fuel cells and solar panels, researchers' efforts in power supply are directed towards achieving a more friendly environmentally vehicle, with high autonomy and reliability.
There are many ways to connect the fuel cells, solar panels, batteries, supercapacitors and vehicle motor to run the vehicle. For example, solar energy has advantages, but is not suitable to run a vehicle directly, on its own. It is needed a fuel, because the driver wants to be independent of the sunlight. Also, there are hybrid vehicles in development and in production that combine classical batteries and fast supercapacitors - as method of propulsion. This presentation deals with hybrid energy systems based on fuel cells and solar panels vs. alternative solution composed by batteries and supercapacitors. Main general parameters as: power, energy and efficiency are compared through theoretical and experimental studies for both hybrid systems. Specific parameters, as: heating value or thermal efficiency for fuel cell, power density for solar panel, life cycle for supercapacitors, state of charge for batteries are also computed and analyzed. Advantages of using both systems are discussed and results obtained trough simulations and experiments come to certify conclusions of each scenario.
