The present application provides a battery power control method, a control device, and a battery system, which relate to the field of battery technology. The method includes: obtaining multiple historical discharge currents of the target battery and the current target battery temperature in real time when the target battery is discharged. and the current state of charge, multiple historical discharge currents are multiple discharge currents of the target battery within a historical time period; determine the maximum discharge current according to the current target battery temperature and the current state of charge; adjust according to multiple historical discharge currents The maximum discharge current, so that the duration of the pulse discharge current of the target battery during the discharge process is less than a predetermined value; calculate the product of the adjusted maximum discharge current and the current discharge voltage to obtain the maximum discharge power; control the discharge power of the target battery to be less than the maximum discharge power. The method solves the problem that the battery power control method in the prior art has the risk of exceeding the battery's own power capability and damaging the battery.
Description
technical field [0001] The present application relates to the field of battery technology, in particular, to a battery power control method, a control device, a computer-readable storage medium, a processor, and a battery system. Background technique [0002] As a key component of the powertrain of electric vehicles and hybrid electric vehicles, the power battery pack is the main energy storage unit of electric vehicles, providing energy for the whole vehicle to run. When the vehicle is accelerating, the battery pack usually needs to be discharged for a short time at a high rate. When the vehicle is running at a constant speed range, the battery pack needs to be discharged at a lower rate for a long time. The driving state of these two kinds of cars corresponds to the short-term high-rate discharge of the battery pack during acceleration, which can be called pulse discharge, and this time is usually ≤ 60s. The low-rate discharge of the battery pack used when the vehicle is ...
