SoC (State of Charge) indicates the charge level of the battery. It expresses how much energy is currently stored in the battery relative to its maximum capacity. Simply put, it shows how full the battery is at a given moment. This indicator is essential for the practical use of batteries, as it informs the user about the amount of energy currently available.

A One-hundredth rally (Regularity rally) is a specific type of automobile competition where the outcome is not decided by speed, but by the precision of the times achieved. Crews follow a detailed itinerary, and their main goal is to avoid getting lost and to pass through checkpoints at precisely predetermined times. The competition primarily features historic vehicles.

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.
