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.

A hybrid electric vehicle (HEV) is a car that can independently run on fossil fuels and electric power. HEV vehicles are typically equipped with only a smaller traction battery and a less powerful electric motor. However, the electric motor’s performance is sufficient for the vehicle to run solely on electric power.
