Problems solved by technology

[0004] In the prior art, ordinary 48V battery SOC management only has a constant target SOC. Under different working conditions, load power supply requirements are different. If only a constant target SOC is used to judge, NVH problems will occur, resulting in increased fuel consumption.

Abstract

The invention discloses a control method and device, equipment and a storage medium. The method comprises the steps of obtaining the current working condition of a vehicle; determining a target charge state according to the current working condition; acquiring the current charge state of a 48 V battery of the vehicle; and if the current charge state of the 48 V battery is larger than the target charge state, controlling the 48 V battery to supply power to the whole vehicle load. According to the technical scheme, different target charge states can be set according to different working conditions, it is avoided that engine torque is consumed for power generation as much as possible, on one hand, idling oil consumption is reduced, and on the other hand, NVH during idling is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular to a control method, device, equipment and storage medium. Background technique [0002] SOC (State of Charge, battery state of charge) is also called the remaining power, which represents the ratio of the remaining dischargeable power of the battery after it has been used for a period of time or left unused for a long time to the power of the fully charged state, usually expressed as a percentage. It is generally expressed in one byte, that is, two-digit hexadecimal (the value range is 0-100), which means that the remaining power is 0%-100%. When SOC=0, it means that the battery is completely discharged. When SOC= 100% means the battery is fully charged. [0003] NVH (Noise, Vibration, Harshness) is a comprehensive problem to measure the quality of automobile manufacturing, and it gives the most direct and superficial feeling to car users. The NVH p...
