Beschreibung
Zusammenfassung:	The present disclosure provides a method for controlling the coolant flow of a liquid-cooled power battery, a system, and a vehicle. The method obtains a relationship between a temperature difference within a battery pack and a temperature difference within the coolant, and deduces a target temperature difference within the coolant according to a target temperature difference within the battery pack and the relationship between the temperature difference within the battery pack and the temperature difference within the coolant. The method determines a required flow capacity of the coolant according to the target temperature difference within the coolant, and controls a battery cooling pump to operate according to the required flow capacity of the coolant. The problem of higher energy consumption existing in existing liquid-cooled battery packs for controlling the temperature difference within the battery pack is resolved by the disclosure.
