The training platform is based on the real object of the driving system of the vehicle, including detection panel, motor driving system, gear switch, acceleration control device, DC contactor, etc., which can truly show the composition structure and working process of the driving system of new energy vehicles.
2 Functional requirements
a. The real and operable new energy vehicle drive system is connected with other platforms of the system to complete the composition structure and working process of the new energy vehicle drive system.
b. The measuring panel of the training platform is painted with color spray circuit diagram, which is made of 8mm thick high-strength acrylic plate. It has the characteristics of large temperature difference resistance, wear resistance, moisture resistance, corrosion resistance, not easy to deformation, long service life, bright color and not easy to fade. The panel is printed with color circuit diagram that will never fade, and the surface is sprayed with varnish; Students can intuitively compare the circuit diagram and the real object of the electric vehicle drive system to understand and analyze the working principle of the control system.
c. A detection terminal is installed on the panel of the training platform, which can directly detect the electrical signals of the pins of each control unit, such as resistance, voltage, current, frequency signals, etc.
3 Process standard: the circuit diagram board has the function of circuit analysis, the graphic circuit is made of acrylic plate by laser spraying, and the frame is pressed and inlaid with aluminum alloy frame, which is beautiful and generous. The base of the bench is assembled with national standard aluminum profiles. The base is equipped with universal moving casters with reasonable line distribution. The electrical installation is organized and implemented in strict accordance with GB national electrical industry standards.
