Vehicle-to-Grid (V2G) technology enables the use of energy stored in electric vehicle batteries and its return to the power grid. The V2G technology makes the EV battery available as a kind of mini-storage. Using V2G can bring benefits not only to electric vehicle owners but to society as a whole.

SoH (State of Health) indicates the overall technical condition of a battery or its cell. It expresses the ratio between the current capacity and the original rated capacity of a new battery. In other words, SoH reflects the degree of battery wear. This indicator is crucial, for example, when assessing the condition of a battery in a used electric vehicle.

Cars carrying the eHybrid (e-HYBRID) designation have a plug-in hybrid electric drive, which means they can use a traditional internal combustion engine, an electric motor or a combination of the two. Hybrid eHybrid (e-HYBRID) cars allow driving solely on electric power.

Power electronics is a very important and integral part of the powertrain unit of every electric vehicle. The power electronics of an electric drive system control the transfer of energy between the main components of electric vehicles, such as the battery, the electric motor, and the charger. The efficiency of a given electric drive is significantly influenced by the architecture of the power electronics.
