Abstract

The invention is applicable to the technical field of electric loaders, and provides an electric engineering mechanical hybrid power supply type electric control management system. The system comprises a power generation device, a battery system, a five-in-one controller and a whole vehicle controller, and the battery system comprises a low-voltage power supply system and a high-voltage power supply system; the power generation device comprises an engine, a generator and detection systems, the detection systems are connected with the generator and the whole vehicle controller correspondingly,the detection systems comprise the heavy load detection system, the medium load detection system and the light load detection system, and all the detection systems are connected with the battery system and the generator; the whole vehicle controller is connected with the five-in-one controller, and the generator and the battery system are connected with an oil pump motor and a traveling motor through a motor controller; and the battery system, the five-in-one controller and a pump motor controller are connected with one another through a CAN transmission system and a low-voltage transmission signal. The system can effectively control the traveling motor and the oil pump motor, reduce the power consumption and improve the working efficiency.

Description

technical field [0001] The invention relates to the technical field of electric loaders, in particular to a hybrid power supply electric control management system for electric engineering machinery. Background technique [0002] At present, the loaders used in the industry generally rely on internal combustion engines to provide power. However, due to the continuous increase in fuel prices, the operating costs of fuel-powered loaders continue to increase. At the same time, fuel will cause serious air pollution. With people's environmental protection and energy conservation awareness With continuous enhancement, fuel-powered loaders are gradually unable to meet the needs of the times. The document with the application number CN201410656556.6 discloses an electric loader, which can be powered by an onboard battery pack, and can also be connected to an external power supply to provide power from an external power supply. When using an external power supply, the battery pack can...

Problems solved by technology

However, the electrical control system disclosed in this document uses a single battery pack to provide power to the whole machine, which consumes a lot of battery, and in the control process, when lifting, the speed of the travel motor changes with the speed of the oil pump motor, resulting in Occurrence of power consumption

In the prior art, for the vehicle power supply system, if the battery is charged for a long time, the battery will be damaged, and recharging when the battery is exhausted will affect the work efficiency

[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
