Power output method and system adopting IEMS to control battery and capacitor composite energy storage equipment

Abstract

The invention discloses a power output method adopting IEMS to control battery and capacitor composite energy storage equipment. The IEMS is used for conducting corresponding intelligent optimizationcontrol over the power output of the composite energy storage equipment according to power required by different application scenarios. A long-life-cycle low-consumption discharge rate, namely, a C-rate, is subjected to intelligent optimization according to battery types so as to set the composite output proportions of a battery and a capacitor in the composite energy storage equipment under different scenarios, so as to enable the battery to be always operated at the optimal rate, and achieve the purpose of long-distance and long-life-cycle use. The output proportion of a composite energy source is controlled according to the power required by different scenarios. By means of the method, some performance of the circulating battery is improved, the service life of the battery is prolonged,the capacitance performance of the circulating battery is fully utilized to adapt to different application scenarios, and the user experience feeling of an electric vehicle in the driving process isenhanced.

Problems solved by technology

[0003] Electric vehicles run in different states and have different requirements for batteries. When driving at low speeds, electric vehicles do not require high discharge power from batteries. When driving at high speeds, electric vehicles have high requirements for discharge power. High-power discharge, and the discharge performance of the same battery often cannot meet the requirements of vehicle operation in different states. When the battery is used for a period of time, the performance of the battery will decline, resulting in the inability to output high power during use, which directly affects the use of users. to experience

[0004] In addition, when the electric vehicle is running in different application scenarios, since the output power required by different application scenarios is different, it is necessary for the energy storage device to adapt to different application scenarios and output different power. state, it is necessary to provide high-power power output for a long time, the existing battery output power is always limited, which cannot meet this demand, and the electric vehicle makes the vehicle in a short time during driving or other situations. The output power is greater, so that the electric vehicle that is trapped in the pit can be driven out of the pit
