The whole test solution consists of six kinds of testing equipment, which can realize special battery formation and experimental testing, power battery unit test, power battery module test, power battery assembly (battery pack) test, electric vehicle charging pile (machine) test, and a battery management system (BMS) testing and other functions, has become the ideal choice test production and development of new energy vehicle powertrain.
And the battery formation assay aspect, the CLP provided Bitrode Ruihua battery formation and production of special testing equipment with ease of use, accuracy and reliability, the advantages of high stability, using the most advanced software tools (circuit control and data acquisition), battery manufacturing automation and simulation tools, and laboratory accessories (water bath, battery holder, charging jumper), applied research and electrochemical cell is suitable for all. The device has energy recovery capabilities that return energy to the grid, thereby virtually eliminating heat dissipation. Leading-edge HEV / EV battery, module and component test systems provide turnkey solutions for users.
CLP Ruihua's power battery cell test solution uses standard electric vehicle test FUDS, SFUDS, GSFUDS, DST and ECE-15L to drive simulation, and the drive cycle conversion utility can use the collected battery usage data to automate test program development. Other features of the solution include: constant current, power or voltage control; bipolar capacitor discharge capability below zero volts; more flexible parallel circuit operation in test specifications; assignable data channels; test control and data using Bitrode's VisuaLCN management.
The power battery module test solution provided by CLP Ruihua has the same functions as the power battery unit test solution, and also has the recovery discharge power delivered to the AC line for cooler, more energy-efficient operation; undervoltage control without performance Loss; remote binary protocol over Ethernet connections controlled by third-party software; program execution is independent of PCs using VisuaLCN software.
In the test of power battery assembly (battery pack), the solution provided by CLP Ruihua adds a built-in isolation transformer, AC input filter, and DC output filter to the above two solutions to ensure compatibility with BMS or Stable communication of the ECU; all units are constructed in accordance with CE specifications; only 20 minutes of software-based full calibration; including the safety of the circuit when the cabinet door is open.
CLP Ruihua's electric vehicle charging pile (machine) test system can simulate and test the output of different charging equipment modes, such as constant current to constant voltage, constant current, constant voltage, fast charging, etc.; it can fully simulate the actual loading of charging piles. In addition to constant current (CC), constant voltage (CV), constant resistance (CR) and constant power (CP), the CZ fixed impedance mode is added to simulate inductive or capacitive loads. And the load ramp can be set with an adjustable slope space of 0.0001 to 2.5 A/μs. The test parameters include AC input characteristic test, DC output characteristic test, overall characteristic test, protection characteristic test and special function test.
The battery management system is the link between the battery and the user. The battery management system (BMS) test solution of CLP Ruihua is the equipment for testing it. It helps to improve battery utilization, balance battery power, maintain battery consistency, extend battery life, and accurately evaluate and monitor battery capacity. The scheme consists of high-precision single-cell voltage analog source, high-precision constant current source, high-precision high-voltage constant-voltage source, electronic load, high-precision temperature acquisition module, control computer, CAN bus analyzer, BMS power supply, insulation resistance tester, Insulation withstand voltage tester, I / O switch board, console, communication module and other components. It is suitable for functional verification including: battery charge and discharge control function, battery total voltage and current monitoring function, battery cell voltage monitoring function, battery pack temperature management function, battery pack safety control function, fault diagnosis and processing function, inter-system communication function And battery SOC estimation function. The program can realize the full-scale real-time simulation of the working state of the BMS system, and provide an accurate scientific basis for the safety and reliability assessment of the BMS system. It mainly focuses on the development of BMS production, performance testing, and BMS management systems, including electric vehicles. Distributed energy storage power stations, microgrid energy storage, etc.
In the original football stadium, basketball stadium or other competition venues, the advertisements, notices or publicity in the on-site stadium are realized by spraying cloth. The display content is single, imperfect, and can not be reused. The dismantled spraying cloth causes waste, recycling difficulty, pollution and a series of problems, which can not meet the needs of modern competition. The demand of the market naturally makes the Stadium LED Display act as the agent of the original spray painting cloth. Led Stadium screen can fully meet the needs of how to compete, so that the organizers can get more benefits and avoid unnecessary waste.
Stadium Led Display features:
1. Diversified display, repeated display, more content display, short time-sharing display, scrolling display, temporary change of content, addition of content, setting of display duration and interval time, etc.
2. Safety: the cabinet is equipped with soft cotton body, and the display surface is equipped with soft mask. When the athletes hit the screen body, the safety of far mobilization is guaranteed.
3. The cabinet body is easy to remove and install. The screen body of the stadium adopts a single box structure, which can be removed and installed at any time. For a standard football stadium, the removal and installation takes only 3 hours.
4. Visual adjustment of the cabinet . There is a support bar at the back of each cabinet. The angle can be adjusted at 75 ° - 90 ° to ensure the audience's viewing effect. At the same time, the support foot is a certain height from the design cabinet to the ground, which can effectively waterproof.
5. The refresh frequency is above 3830 Hz, and the camera can also capture wonderful pictures. Let the TV audience see a clear and dynamic picture.
Stadium Led Display application place: outdoor football venues, indoor basketball venues, skating rink and other sports events.
Structure and product principle: single cabinet structure is adopted, stable and safe waterproof air plug connection is adopted between each cabinet, and each cabinet is provided with adjustable support base. Data can be sent wirelessly and wirelessly.
