Abstract

The invention discloses a control method and a control device for a power supply device, a power supply system and equipment. The control method comprises the following steps of acquiring the current voltage of a storage battery; and when the current voltage of the storage battery is lower than the starting voltage of an engine, and a charging device is determined to be consistent with a preset condition, controlling the charging device to charge the storage battery. According to the scheme, the technical failure that the engine cannot be started due to the insufficient voltage of the storage battery can be prevented.

Description

technical field [0001] The present invention relates to the technical field of control, in particular to a control method, device, power supply system and equipment of a power supply device. Background technique [0002] In the low-voltage electrical system of the current equipment, such as figure 1 The power supply shown supplies power to lighting system loads, cooling system loads, etc. loads in the equipment. The power supply device includes a power-on switch S, a battery GB, an engine, a generator and a load L. When the system is powered on, the battery GB provides the starting voltage of the engine. After the engine starts, the generator is driven, and the generator absorbs the output of the engine. The power is generated, and the output power is used to supply power to the system. [0003] The inventor of the present application found that, in the prior art, if the electric energy consumed by the load is too large and exceeds the rated output power of the generator, ...
