Embodiment Construction
[0025] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0026] figure 1 It is a structural schematic diagram of the control system of the low-power fuel cell vehicle of the present invention.
[0027] like figure 1 As shown, the present invention provides a control system for a low-power fuel cell engine vehicle on the one hand, including: a low-power fuel cell engine 1, a DC / DC converter 2, a fuel cell manager 3, a power battery 4, and a power battery manager 5. Motor 6, motor controller 7, mode selection switch 8, inverter 9 and vehicle controller 10. Among them, the fuel cell manager 3 controls the low-power fuel cell engine 1 and the DC / DC converter 2 (such as a high-voltage DC / DC converter), and forms a fuel cell system with the low-power fuel cell engine and the DC / DC converter. The power battery man...
