Technical Field
[0001] This invention relates to the field of new energy vehicle technology, specifically to an air compressor system for new energy vehicles that integrates cooling, drying, and intelligent control. It is particularly suitable for the braking air supply scenario of new energy vehicles and applicable to various types of new energy vehicles. It can also provide technical reference for related industrial air compressors. Background Technology
[0002] With the rapid development of the new energy vehicle industry, its braking system places higher demands on the performance, integration, and intelligence of air supply equipment. Currently, automakers are accelerating their technological iteration, and more and more car companies are requesting integrated air compressor supply solutions to simplify the assembly process of new energy vehicles and reduce the difficulty of adapting braking systems.
[0003] Existing automotive air compressor systems have several shortcomings, making it difficult to meet the stringent requirements of new energy vehicle braking scenarios: First, the functional modules (such as cooling, drying, and air storage) are mostly decentralized with low integration. During new energy vehicle assembly, multiple components need to be installed and debugged individually, resulting in a cumbersome process and poor compatibility with the braking pipelines and cooling systems of new energy vehicles. Second, the control methods are relatively simple, lacking dynamic adaptability to different driving conditions of new energy vehicles (such as frequent braking in congested areas, driving in extremely cold environments, and periods of high air consumption), leading to insufficient stability of braking air supply and energy utilization. Third, the drainage system design is inadequate, making it prone to water accumulation, freezing, or corrosion in pipelines and air storage components, directly affecting the braking safety of new energy vehicles and the system's lifespan. Fourth, there is a lack of specific fault monitoring and alarm mechanisms for new energy vehicle braking scenarios, making it impossible to promptly report problems such as abnormal air pressure and malfunctioning drain valves, resulting in high maintenance costs and safety hazards.
[0004] Therefore, designing an air compressor system that is highly integrated, intelligent, widely adaptable, and can accurately match the braking air supply needs of new energy vehicles has become an urgent technical requirement to be addressed in this field. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated air compressor system for new energy vehicles that integrates cooling, drying and intelligent control. This system is highly adaptable to the braking air supply scenario of new energy vehicles, with high integration, convenient installation and high level of intelligence. It can adapt to different working conditions and new energy vehicle models, improve the stability of braking air supply and system reliability, and ensure the driving safety of new energy vehicles.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An integrated air compressor system for new energy vehicles, incorporating cooling, drying, and intelligent control, includes an integrated controller, an air compressor body, a cooling module, a drying module, an air storage module, a sensing module, and an execution module. The integrated controller is electrically connected to the air compressor body, cooling module, drying module, sensing module, and execution module, respectively, and receives detection signals from the sensing modules and outputs control commands to dynamically adjust the air pressure requirements of the new energy vehicle's braking system. The new energy vehicle only needs to provide high-voltage and low-voltage electricity to the integrated controller, with a reserved alarm signal port for communication. The air storage module is connected to the new energy vehicle's braking pipeline via a predetermined mechanical port, and the cooling module is connected to the new energy vehicle's cooling circuit or heat dissipation system via a predetermined mechanical port. This enables coordinated operation between the system and the new energy vehicle's braking air supply system, providing a stable air source for braking. The system supports cabinet-type prefabricated installation or split-type installation, adapting to the spatial layout of different new energy vehicle models.
[0008] Furthermore, the high voltage is DC540V or higher, and the low voltage is DC12V or DC24V, commonly used voltages for new energy vehicles; the sensing module includes at least five sensors, which are used to detect the water level or humidity of the gas storage module, the braking system pressure of the new energy vehicle, the air supply pressure of the whole vehicle, the operating temperature of the new energy vehicle, and the intake negative pressure of the air compressor.
[0009] Furthermore, the cooling module includes a cooling coil, a condenser, a cooling fan, and an optional water pump; the cooling fan is adapted to the condenser, the water pump is used in the cooling circuit of the water-cooled air compressor and works in conjunction with the cooling system of the new energy vehicle, and the integrated controller controls the start and stop of the cooling fan according to the condenser intake temperature detected by the temperature sensor, and controls the start and stop of the water pump according to the operating environment temperature of the new energy vehicle detected by the temperature sensor, adapting to the heat dissipation needs of the new energy vehicle under different driving conditions.
[0010] Furthermore, the drying module includes a dryer, the unloading pressure of which is set to 1050 kPa. The integrated controller controls the start and stop of the air compressor body according to the vehicle air pressure detection signal. When the air pressure of the new energy vehicle brake supply is lower than 700 kPa, the air compressor body is started, the air is pumped to 1000 kPa and then stopped after a delay of 8-12 seconds to ensure the air pressure of the new energy vehicle braking system is stable.
[0011] Furthermore, the execution module includes an air filter backflushing mechanism and a drain valve; the air filter backflushing mechanism is connected to the air storage module, and the integrated controller controls the backflushing mechanism to start according to the cumulative running time of the air compressor body or the detection value of the intake negative pressure sensor, so as to ensure smooth air intake of the air compressor during the operation of the new energy vehicle.
[0012] Furthermore, the drain valve includes a condenser drain valve and an electric drain valve for the air reservoir; the condenser drain valve operates once after being powered on during air compressor operation, and then operates once every 15-25 seconds, with each operation lasting 1-3 seconds; the electric drain valve for the air reservoir operates once every 0.8-1.2 hours, with each operation lasting 1-3 seconds, to prevent moisture from accumulating in the brake lines and air reservoir components of the new energy vehicle and affecting braking safety.
[0013] Furthermore, the integrated controller has a load rate monitoring function, where load rate = (inflating time) / (inflating time + interval time) × 100%. When the interval inflating time is detected to be less than the rated interval time, the integrated controller controls the air compressor to speed up to increase the exhaust volume, adapting to high air consumption scenarios such as frequent braking of new energy vehicles. When the interval inflating time returns to normal, the air compressor returns to its rated speed, and the load rate is controlled below 25%, reducing the energy consumption of new energy vehicles.
[0014] Furthermore, when the sensor used to detect the braking system pressure of the new energy vehicle detects that the system pressure is below 680 kPa, the integrated controller forcibly outputs high-voltage electricity to start the air compressor body, ensuring emergency air supply for the new energy vehicle's braking; when the sensor used to detect the water level or humidity of the air storage module detects abnormal water level or excessive humidity, the integrated controller sends a feedback alarm to the new energy vehicle's vehicle control system through a reserved alarm signal port to facilitate timely early warning and maintenance of the new energy vehicle.
[0015] Furthermore, when the temperature sensor detects that the ambient temperature of the new energy vehicle is around zero degrees Celsius, the integrated controller controls the water pump to stop working, realizing the energy-saving operation of the water-cooled air compressor in winter and adapting to the low-temperature operating conditions of new energy vehicles in winter.

[0020] Figure 1 is an exploded structural diagram of the integrated cooling, drying and intelligent control air compressor system for new energy vehicles according to the present invention. Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0022] An air compressor system for new energy vehicles that integrates cooling, drying and intelligent control includes an integrated controller, an air compressor body, a cooling module, a drying module, an air storage module, a sensing module and an execution module.
[0023] The integrated controller uses an STM32 series microcontroller as the core control unit. It has multiple analog and digital input / output interfaces and can be electrically connected to components such as the air compressor body, cooling fan, water pump, sensor, drain valve, and air filter backflushing mechanism to realize signal acquisition and control command output. It is primarily adapted to the dynamic air supply requirements of the braking system of new energy vehicles.
[0024] The high-voltage power supply uses DC540V, and the low-voltage power supply uses DC24V, a common power supply for new energy vehicles. These power the air compressor body and the integrated controller, respectively. The new energy vehicle has a reserved CAN bus alarm signal port for communication with the integrated controller to receive system abnormal alarm information and ensure the new energy vehicle's monitoring of the brake air supply system.
[0025] The cooling module includes a cooling coil, a condenser, a cooling fan, and a water pump. The cooling coil is connected to the exhaust port of the air compressor body, the condenser is connected to the cooling coil, and the cooling fan is installed on one side of the condenser and electrically connected to the integrated controller. The water pump is connected in series in the cooling circuit of the water-cooled air compressor and electrically connected to the integrated controller. The water pump pipeline is connected to the new energy vehicle cooling system through a predetermined mechanical port to achieve coordinated operation with the heat dissipation of the new energy vehicle.
[0026] The drying module uses a conventional automotive dryer with an unloading pressure set at 1050 kPa. The dryer's air inlet is connected to the condenser, and its air outlet is connected to the air storage module to ensure that the gas entering the brake line is dry and clean.
[0027] The air storage module uses an automotive air tank, which is directly connected to the brake line of the new energy vehicle through a predetermined mechanical port. An electric drain valve and a water level / humidity sensor are installed on the air tank. The electric drain valve is electrically connected to the integrated controller, and the signal output terminal of the water level / humidity sensor is connected to the signal input terminal of the integrated controller to monitor the moisture status inside the air tank in real time.
[0028] The sensing module includes five sensors: Sensor 1 (water level / humidity sensor) is installed inside the air tank to detect the water level and humidity inside the air tank, preventing moisture from entering the brake lines; Sensor 2 (new energy vehicle braking system pressure sensor) is installed in the new energy vehicle brake air supply main line to accurately detect the brake system pressure; Sensor 3 (vehicle air supply pressure sensor) is installed at the air tank outlet to detect the vehicle air supply pressure; Sensor 4 (temperature sensor) is installed on the condenser to detect the condenser intake temperature and the operating ambient temperature of the new energy vehicle; Sensor 5 (negative pressure sensor) is installed at the air inlet of the air compressor body to detect the intake negative pressure. This embodiment uses five sensors, and the number of sensors can be increased according to the actual needs of the new energy vehicle braking system.
[0029] The execution module includes an air filter backflushing mechanism and a drain valve. The air filter backflushing mechanism includes a backflushing solenoid valve and a backflushing air pipe. One end of the backflushing air pipe is connected to the air tank, and the other end is aligned with the air filter element. The backflushing solenoid valve is electrically connected to the integrated controller. The drain valve includes a condenser drain valve and an electric drain valve for the air tank. Both are electromagnetic drain valves and are electrically connected to the integrated controller. The drainage logic is specifically designed for the waterproofing requirements of the brake lines of new energy vehicles.
[0030] In this embodiment, the system adopts a cabinet structure design, integrating the controller, cooling module, drying module, gas storage module, and execution module into one cabinet. The cabinet is equipped with a high-voltage power interface, a low-voltage power interface, an alarm signal interface, and a mechanical connection port. The new energy vehicle only needs to connect the power supply and alarm interface through cables, and connect the gas storage module to the brake pipeline and the cooling module to the new energy vehicle's cooling system through pipelines to complete the installation, adapting to the spatial layout requirements of the new energy vehicle model.
[0031] When the system is working, after the integrated controller is initialized, the sensors begin to collect various data and transmit them to the integrated controller, with the core focus on regulating the braking air supply demand of new energy vehicles:
[0032] When sensor 3 detects that the vehicle's air supply pressure is below 700 kPa, the integrated controller outputs a control signal to start the air compressor. The air compressor begins to pump air, which is cooled by the cooling coil, further cooled by the condenser, and dried by the dryer before entering the air storage tank. It then supplies air to the new energy vehicle's braking system through the brake lines. When the air pressure reaches 1000 kPa, the integrated controller controls the air compressor to stop after a 10-second delay. If sensor 2 detects that the new energy vehicle's braking system pressure is below 680 kPa, the integrated controller forcibly starts the air compressor to ensure emergency braking air supply.
[0033] The integrated controller calculates the load rate in real time. When it detects that the interval between air pumping cycles is less than the rated interval (e.g., the preset rated interval is 30 seconds, but if the new energy vehicle brakes frequently, the actual interval is 20 seconds), the integrated controller controls the drive motor of the air compressor to speed up and increase the exhaust volume to adapt to the high-occurrence air consumption scenario of frequent braking. When the interval between air pumping cycles returns to more than 30 seconds, the air compressor returns to the rated speed, and the load rate is controlled below 25%, reducing the energy consumption of new energy vehicles.
[0034] Sensor 4 detects the condenser intake air temperature. When the temperature exceeds 50°C, the integrated controller starts the cooling fan. When the temperature drops below 40°C, the cooling fan stops working. For water-cooled air compressors, when sensor 4 detects that the ambient temperature of the new energy vehicle is around 0°C, the integrated controller controls the water pump to stop working to prevent low-temperature freezing from affecting the cooling system of the new energy vehicle and the operation of the air compressor. When the ambient temperature exceeds 5°C, the water pump starts normally to achieve energy-saving operation in winter.
[0035] The integrated controller accumulates the operating time of the air compressor body. When the operating time reaches 100 hours, it controls the backflush solenoid valve to open, and the high-pressure gas in the air tank backflushes the air filter element through the backflush pipe for 5 seconds. If sensor 5 detects that the intake negative pressure is less than -400KPa, the integrated controller immediately starts the backflush solenoid valve to backflush, ensuring smooth air intake of the air compressor during the operation of new energy vehicles and avoiding insufficient air intake from affecting the brake air supply.
[0036] The condenser drain valve activates once immediately after the air compressor is powered on, lasting 2 seconds. Subsequently, it activates once every 20 seconds, each time lasting 2 seconds, during the air compressor's pumping operation. The air tank electric drain valve activates once every hour, each time lasting 2 seconds, to completely drain water from the system and prevent water from accumulating in the brake lines, freezing, or corroding components. If sensor 1 detects that the water level in the air tank exceeds a preset threshold (e.g., 5mm) or the humidity exceeds 80%, the integrated controller sends a drain valve failure alarm signal to the new energy vehicle via the CAN bus, reminding the driver to perform timely maintenance.
[0037] The integrated cooling, drying, and intelligent control air compressor system for new energy vehicles in this embodiment has a high degree of integration and is easy to install. It can be adapted to both air-cooled and water-cooled air compressors and can dynamically adjust its operating status according to different driving conditions of new energy vehicles. This effectively improves the stability of braking air supply, system reliability, and energy utilization, while reducing maintenance costs. It is suitable for all types of new energy vehicles.
[0038] A new energy vehicle includes the aforementioned integrated air compressor system for new energy vehicles that combines cooling, drying, and intelligent control. This system provides a stable and safe air source for the braking of the new energy vehicle, thereby improving its braking performance and driving safety.
[0039] In summary, this integrated air compressor system for new energy vehicles combines cooling, drying, and intelligent control.
[0040] Highly adaptable to the braking scenarios of new energy vehicles, and convenient integrated installation: The system is designed specifically for the braking air supply of new energy vehicles, integrating all functional modules into one. The air storage module is directly connected to the braking pipeline of new energy vehicles, and the cooling module is adapted to the cooling system of new energy vehicles. The whole vehicle only needs to be connected to the power supply, reserve the alarm port and connect the mechanical interface to operate. It supports cabinet or split installation, greatly simplifying the assembly process of new energy vehicles and reducing the difficulty of adapting the braking system.
[0041] High level of intelligence and precise adaptation to working conditions: The integrated controller enables centralized management and control of all modules. It dynamically adjusts operating strategies such as air pressure control, load adjustment, and cooling mode for different working conditions such as frequent braking and low-temperature driving of new energy vehicles without manual intervention. This ensures the stability of braking air supply while also taking into account the energy-saving needs of new energy vehicles.
[0042] Stable air supply pressure ensures braking safety: By using dual sensors to monitor the braking system pressure and the vehicle's air supply pressure, multiple control thresholds are set: start when below 700KPa, forced start when below 680KPa, and stop when reaching 1000KPa. Combined with the dryer unloading pressure design, this ensures that the braking air pressure is always within a safe range, avoiding abnormal air pressure from affecting the braking effect.
[0043] With a robust protection mechanism and high system reliability, the multi-point intelligent drainage mechanism addresses the issue of water accumulation in the brake lines of new energy vehicles by enabling high-frequency, periodic drainage, coupled with drainage fault alarms. The air filter features dual-condition backflushing with "duration + negative pressure" to ensure smooth air intake. Multiple sensors comprehensively monitor key parameters, and the emergency protection logic is robust, effectively extending the system's service life and reducing braking safety risks.
[0044] Wide versatility and significant cost advantages: Compatible with various types of air compressors, including air-cooled and water-cooled models, suitable for new energy vehicles and various new energy vehicles requiring braking air supply, while also supporting different vehicle space layouts; intelligent self-cleaning and automatic drainage functions reduce the frequency of manual maintenance, and optimized component coordination logic reduces losses, resulting in a more cost-effective long-term use.
[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
