Silence power device

Abstract

The invention discloses a silence power device. The silence power device is characterized by comprising a motor controller, a direct current motor, a hydraulic pump, a storage battery and a charger. The direct current motor is connected with the hydraulic pump, the motor controller is respectively connected with the direct current motor and the storage battery, the storage battery is connected with the charger, a power control system is connected with an engine controller through a power selection switch, the engine controller is connected with an engine, the power control system is provided with a wiring harness connector, the power selection switch is connected with the power control system through a wiring harness, and the motor controller is connected with the power control system through the power selection switch. Compared with the prior art, the silence power device has the advantages that the silence power device can be used as an optional device, matching flexibly of engineering equipment is improved, connection between the silence power device and the power control system is reasonable, two-power switch can be conveniently achieved, working efficiency is high, working noise is low, and the heat dissipation performance is good.

Description

technical field [0001] The invention relates to a silent power device, which belongs to the technical field of dual power control systems, and is mainly used as a power source for high-altitude operation vehicles. Background technique [0002] At present, the operating power source of the vehicle-mounted aerial work vehicle is generally the engine of the chassis. When the engine is working, it will produce a lot of noise, especially when it is constructed in a residential area, it will interfere with the living environment of the residents, and the engine will generate noise. Exhaust gas will also pollute the environment and affect air quality. [0003] The power source of existing high-altitude operation vehicles also adopts dual power settings, which uses both engine power supply and motor power supply at the same time, which provides convenience for the power selection of the vehicle, and can switch different power supplies under different working conditions. When the mo...
