[0002] At present, the charging device of the existing renewable energy power generation system can realize the collection and display of the basic performance parameters in the power generation process during the normal operation of the power generation system, but cannot analyze and calculate the above basic performance parameters to optimize the charging device charging method
The charging device in the prior art cannot store and operate the excess electric energy generated by the renewable energy power generation system, and cannot realize the efficient utilization of renewable energy
In addition, due to the instability of the power supply of the renewable energy power generation system, the energy output by the power generation system is intermittent and unstable. At the same time, when the renewable energy power generation system fails, it lacks fault judgment and charging methods for the power generation system choose

The invention provides a battery charging device based on renewable energy and a control method thereof. The device includes: a power generation unit used to supply power to the battery using renewable energy, and used to store excess electric energy after the power generation unit supplies the battery. The power storage unit, the output end of the power generation unit and the output end of the power storage unit are jointly connected and summarized to the conversion unit for supplying power to the battery, and the DSP control unit is used to collect the status parameters of the power generation unit, Determine the state of the power generation unit. If the power generation unit is in a fault state, use a charging method based on energy estimation to charge the battery. If the power generation unit is in a non-fault state, use a charging method based on power generation prediction. The battery is charged, the output end of the conversion unit is connected to the battery, and the DSP control unit is connected to the storage unit. Thus, efficient utilization of renewable energy is achieved, and at the same time, fault diagnosis and control of the power generation system can be performed. Choice of charging method.
