Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of new energy cement tank trucks, and particularly relates to an emergency switch applicable to new energy cement tank trucks. Background Art
[0002] New energy cement tank trucks are important tools for the cement industry to achieve green transformation. By using new energy vehicles to replace traditional diesel vehicles, it helps to reduce pollution emissions and improve transportation efficiency.
[0003] However, when the battery of a new energy cement tank truck fails and cannot be powered on, it cannot enter the range extender mode either, and the unloading of materials cannot be carried out, resulting in the solidification of cement, and thus the high cost of later removal. Summary of the Invention
[0004] The purpose of the utility model is to provide an emergency switch applicable to new energy cement tank trucks, which can force the battery to be powered on after a failure, ensure that the unloading can be completed, and avoid the solidification of cement.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] An emergency switch applicable to new energy cement tank trucks, the new energy cement tank truck includes a power management system, and a battery pack, a main relay, a pre-charge relay and a charging negative relay connected to the power management system; the emergency switch includes an emergency stop button and an emergency button, and both the emergency stop button and the emergency button are connected to the constant power pin of the power management system;
[0007] The emergency stop button is respectively connected to the main relay, the pre-charge relay and the charging-main negative relay. When the emergency stop button is pressed during a failure, the power supply of the relay is disconnected, and the battery management system is restarted; the emergency stop button is connected to the power management system;
[0008] The emergency button is connected to the power management system. When the emergency button is pressed, the power management system starts emergency power-on, and the new energy cement tank truck unloads materials.
[0009] Further, both the emergency stop button and the emergency button are connected with LED lights.
[0010] Further, both the emergency stop button and the emergency button are installed on the power supply box body.
[0011] The utility model designs an emergency start button outside the power supply box body. When the button is pressed, the BMS starts the emergency mode, shields some minor faults (except for faults that cause the battery to catch fire and explode), forces the battery to be powered on, starts the engine to enter the range extender mode, and ensures that the unloading can be completed. After the system restarts, it can exit the emergency mode and return to the normal mode. Description of the Drawings
[0012] Figure 1 This is a schematic diagram of the circuit structure of part A of the present utility model.
[0013] Figure 2 This is a schematic diagram of the circuit structure of part B of the present utility model Specific embodiments
[0014] The new energy cement tanker includes a battery pack, a battery management system, a main relay, a pre-charge relay, and a charge-main negative relay. In this embodiment, the 56S integrated control module is taken as an example of the power management system. The data acquisition pins JP20 and JP40 of the 56S integrated control module are connected to a data acquisition card, and the data acquisition card is connected to the battery pack to realize the monitoring and management of the battery pack.
[0015] The main relay is connected to the main control pin JP9 of the 56S integrated control module, the pre-charge relay is connected to the pre-charge control pin JP25 of the 56S integrated control module, and the charge-main negative relay is connected to the charge control pin JP25 of the 56S integrated control module.
[0016] As Figure 1 and Figure 2 shown, an emergency switch applicable to a new energy cement tanker provided in this embodiment includes an emergency stop button and an emergency button. Both the emergency stop button and the emergency button are connected to the constant power pins JP1 and JP17 of the 56S integrated control module to obtain the working voltage.
[0017] The emergency stop button is respectively connected to the main relay, the pre-charge relay, and the charge-main negative relay. In case of a fault, when the emergency stop button is pressed, the switch is disconnected, the power supply of the battery high-voltage relay is disconnected, and the electro-hydraulic output circuit is disconnected. When rotated clockwise, the switch rebounds and closes, the power supply of the battery high-voltage relay is closed, the battery management system is restarted, and the process of entering the high voltage again is restarted; the emergency stop button is connected to the signal pin JP13 of the 56S integrated control module for the 56S integrated control module to obtain the emergency stop signal.
[0018] The emergency button is connected to the signal pin JP30 of the 56S integrated control module. When the emergency button is pressed, after the 56S integrated control module obtains the emergency power-on signal, it starts emergency power-on to ensure the completion of unloading; in order to reduce the battery loss, after 10 minutes of emergency power-on, it exits the emergency mode and automatically cuts off the power.
[0019] Both the emergency stop button and the emergency button are connected with LED lights, and whether the operation is completed is judged by whether the LED lights are on; to avoid misoperation problems, in this embodiment, the emergency switch is installed on the outer shell of the power supply box.
[0020] The above are only the preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modification and replacement based on the technical solutions and the inventive concept provided by the present utility model should be covered within the protection scope of the present utility model.
