Abstract (en)
[origin: WO2023006330A1] The invention relates to a method for compensating for the internal resistance (R) of an energy storage device (11), in particular an exchangeable replaceable battery pack (10), comprising at least one energy storage cell (42). According to the invention, the internal resistance (R) is compensated for in an electric load (18) or charging device (16), which is connected to the energy storage device (11), on the basis of an exponentially declining approximation (Rapp(T)), the curve of which depends on the temperature (T) and the cell chemistry of the at least one energy storage cell (42). The invention additionally relates to a system consisting of at least one energy storage device (11) designed as an exchangeable replaceable battery pack (10) and an electric load (18) for discharging the exchangeable replaceable battery pack (10) and/or a charging device (16) for charging the exchangeable replaceable battery pack (10). The exchangeable replaceable battery pack (10), the electric load (18), and the charging device (16) each has an electromechanical interface (14, 20) with a plurality of electric contacts (12) for carrying out the method.
