For example, the overload protection scheme in the method may be to switch off a relay, or to request to limit the reported current/power. Generally speaking, if the current/power input by the power supply (charging pile, PCS, etc.) to the battery system exceeds the actual capacity, it often means that the current/power input by the power supply to the battery system exceeds the reported current/power value, possibly because: the power supply has insufficient current/power control capability; the communication between the power supply and the battery system is not timely and effective; the power source selection does not respond to the current/power reporting request of the battery system. In this case, the battery system requests a limitation of the reported current/power, which may be ineffective, and the protective action may be selected to switch off the relay. For certain application scenarios and products, it may be the case that there is a difference. Therefore, the protection action can also be selected as the battery system requesting to limit the reporting current/power in case of triggering overload.
