Abstract

The invention discloses an automatic power distributing direct-current rapid charging machine of an electric automobile and a control method thereof. The automatic power distributing direct-current rapid charging machine comprises a charging cabinet, a first charging pile, a second charging pile and a control system. The charging cabinet is connected with an alternating-current power source. The first charging pile and the second charging pile are connected with the charging cabinet. Monitoring panels are arranged in the first charging pile and the second charging pile. Two automatic distributing units are arranged in the charging cabinet. Each automatic charging unit comprises a plurality of charging modules. The direct-current output end of each charging module is connected with a relay. A normally-open contact and a normally-closed contact of the relay are connected with the first charging pile and the second charging pile correspondingly. The charging cabinet, the first charging pile and the second charging pile are all controlled by the control system. The control strategy is that power can be distributed automatically according to a charging load; and the charging power can be distributed automatically according to state information in the charging process, so that the charging machine has the load adjusting and distributing function, and the load utilization rate is optimized.

Description

technical field [0001] The invention relates to a charger and a control method thereof, in particular to an electric vehicle automatic power distribution DC fast charger and a control method thereof. Background technique [0002] With the rapid development of the automobile industry, the total number of automobiles in the world continues to increase, and the problems of environmental pollution and energy shortage caused by automobiles are becoming more and more prominent. Energy saving and environmental protection have become the two major themes of automobile development in the world today. The sustainable development strategy of the automobile industry and the current situation faced by my country's automobile industry force us to seek a new development path. Electric vehicles have significant advantages such as high efficiency, energy saving, low noise, and zero emission, and have incomparable advantages in environmental protection and energy saving. [0003] The electr...
