With the rapid development of the economy, China's total production, sales and social ownership of industrial vehicles ranked first in the world, and industrial vehicles were widely used in all walks of life of the national economy, providing important logistics support for the production and development of enterprises, and playing an important role in helping the development of the national economy.
After 18 months of intensive research and development, Youdan Technology tailored the A7 new generation iBMS product for the 48V/80V voltage platform of industrial vehicles, comprehensively improving product safety and reliability through innovative technology, effectively reducing system costs, and achieving the ultimate product application experience. Let's explore the uniqueness of the A7 product together.
Safer
Multiple redundant design and dual device-cloud protection
A7 adopts more secure master-slave dual CPU architecture and independent power supply design, when the main CPU is abnormal, the slave CPU can monitor and take over the system in time to ensure that the system enters a safe state, thereby eliminating the security risks caused by software failure.
A7 supports dual-link total voltage/current redundant acquisition to ensure accurate acquisition; Support the main relay two-branch series control to realize the double insurance of the high-voltage circuit, effectively avoiding the extreme situation of overcharge and overdischarge of the battery caused by the failure of the control function.
The A7 application layer adopts model-based MBD development, which greatly improves the code quality; Software programming and OTA upgrades both use UDS standard protocols, which can ensure the stability of software programming.
In addition, A7 and Youdan cloud platform are seamlessly connected, and more than 30 cloud security early warning strategies have been deployed, which can realize 7*24-hour monitoring of battery systems equipped with A7 modules, identify potential battery risks in advance, and actively warn to ensure battery application safety.
More reliable
Handle the complexities of industrial vehicles
The processor chip, acquisition front end and core devices used in A7 are all automotive-grade, and compared with ordinary devices, automotive-grade components have a wider operating temperature, longer design life, and better consistency, ensuring quality from the source.
Structurally, A7 adopts a fully cast aluminum shell, compared with other materials, the cast aluminum shell has better heat dissipation performance and stronger immunity, with circuit optimization, A7 electromagnetic compatibility can reach CLASS 4 level, which can calmly cope with the complex working conditions of industrial vehicles.
A7 has a wealth of hardware interface protection measures, which can resist external electrostatic impact on-board circuits; It supports more than 30 self-diagnoses, such as chip abnormalities, temperature abnormalities, control failures, etc., which greatly improves hardware reliability through technical means.
In terms of power management, the performance of A7 is even more remarkable, and the power consumption can be intelligently adjusted according to the different working states of the battery system, so as to effectively avoid overdischarge caused by long-term battery use.
At present, A7 has passed more than 50 hardware tests such as functional, electrical, environmental, mechanical, safety, electromagnetic compatibility, etc., with more than 300,000 software test cases, and has passed the authoritative test certification of third-party CNAS laboratories and IATF16949 international quality management system process audit, and the quality is trustworthy.
Cheaper
The cost-effective / price-price ratio is both excellent
A7 has made significant optimizations in power supply design, innovatively integrating DCDC, which allows power to be drawn directly from the battery pack without the need for an external power module; At the same time, A7 achieves the standby power consumption to the uA level, eliminating the need for external self-locking relays to reduce the cost of system materials.
In addition, A7 adopts the industry's first three-layer stacked board design, the function is highly integrated, and the board is plugged in through connectors, eliminating the need for complex wiring harness connection, the system is more concise, and the PACK cost is lower.
Based on Youdan's powerful project expert library, automatic compilation tool chain and modular firmware architecture design, A7 products support online automatic generation of code, customers log in to the "Xiaodan Design" platform and select A7 model, check the project configuration to automatically generate code, greatly improve software delivery efficiency, project adaptation cost is lower.
In addition, A7 integrates 4G wireless transmission function, through the remote monitoring platform, it can monitor the battery operation status in real time, realize remote warning/alarm/diagnosis/positioning, support software non-inductive OTA upgrade, and reduce after-sales operation and maintenance costs.
Youdan Technology has accumulated a large number of operating data of lithium batteries in industrial vehicles, and the unique device-cloud collaboration algorithm has been fully implemented in A7. Device-cloud collaborative management based on big data, including cloud full-time balance, cloud SOC correction, and cloud SOP control, can effectively improve the efficiency of lithium battery life cycle management, extend battery service life, and make battery application costs lower and value returns higher.
summary
Youdan Technology has deep industry accumulation, serving more than 300 customers and 10,000 projects, loading hundreds of thousands of vehicles in total, more than 100 billion actual working condition data, more than 100,000 OTA software iterations, and rich experience in field applications.
At present, the process of lithium battery penetration of industrial vehicles is accelerating, and in the face of the torrent of electrification of industrial vehicles, Youdan Technology has shockingly launched A7 new generation iBMS products, which will set off a new wave in the field of new energy. A7, comprehensively exceed expectations, with innovative technology to empower the industry.
