Abstract
In a method for cooling a traction battery of an electrically drivable vehicle, a refrigerant is used as cooling medium, and in a mass flow of specified magnitude is led along the traction battery through at least one channel. The at least one channel is in heat-conducting connection with the traction battery. It is proposed that an available cooling power (P) for cooling the traction battery is determined, wherein as a function of the available cooling power (P), the magnitude of the mass flow of the refrigerant is regulated in such a way that either no cooling power (P) is delivered to the traction battery, or the delivered cooling power (P) in each case assumes one of multiple cooling power stages (I, II) as a function of the available cooling power (P).
