Embodiment 1

[0096] Embodiment 1: The mobile device has two power supply modes during driving, one is that the battery 6 supplies power alone, and the other is that the photovoltaic and the battery 6 supply power simultaneously. figure 2 It is a waveform diagram of the voltage and current output by the storage battery 6 during driving provided by an embodiment of the present invention, and it is the output voltage U when the storage battery 6 supplies power alone. dc And the measured waveform of current I. After turning on the power, the U dc and I are 77V and 0A respectively; turn the accelerator handle to the bottom and start to accelerate, U dc Gradually drop to 69V, I first rises to 50-60A, and then gradually falls back to 35-40A, the vehicle speed is stable at 32km / h; when the accelerator handle is released to slow down and slide, I quickly drops to 0A, U dc It rose back to 76V; the actual measurement results of repeated acceleration and deceleration control showed that I experienc...

Abstract

The invention discloses a mobile photovoltaic pumping system and a control method. The mobile photovoltaic pumping system comprises a photovoltaic array, a photovoltaic control circuit, a main control circuit, a power circuit, a storage battery, a driver, a motor, a water pump driving circuit and a water pump. The storage battery and photovoltaic power generation complement each other, the photovoltaic module can charge the storage battery to provide driving power, and the storage battery can assist the photovoltaic module in providing stable electric energy for the water pumping equipment. Full-automatic and intelligent control over photovoltaic power generation, storage battery charging and discharging and water pump operation is achieved, low-voltage direct current configuration is adopted, and the system safety is high.

Description

technical field [0001] The invention relates to the technical field of photovoltaic applications, and more specifically, to a mobile photovoltaic water pumping system and a control method. Background technique [0002] Photovoltaic water pumping technology has experienced more than 30 years of development, and has formed a rich series of products. The rated power of a single pump ranges from tens of W to hundreds of kW. There are small pumps that can solve the domestic water problems of families or villages in remote areas without electricity. Photovoltaic water pumping, desalination and purification systems, as well as large-scale photovoltaic water conservancy systems for agriculture, forestry, animal husbandry irrigation, desert control, etc. The system composed of photovoltaic arrays, water pumps, controllers and other supporting equipment is usually installed in a fixed way, and water is taken and used nearby. In the early promotion and application, due to the high ini...
