The battery management system (BMS) is the core of electric vehicles and has a great impact on the safe operation of the vehicle, the selection of vehicle control strategies, the selection of charging modes and operating costs. The battery management system must reliably complete real-time monitoring and fault diagnosis of battery status whether during vehicle operation or charging, and inform the vehicle integrated controller or charger through the bus in order to adopt a more reasonable control strategy. Achieve the purpose of effective and efficient use of batteries.
A successful electric vehicle battery management system needs to have the following basic characteristics:
Complete system functions
BMS has powerful functions such as real-time monitoring of battery status, data processing, fault analysis and location, SOC estimation, data transmission, thermal management, charge and discharge control, PC online monitoring, operating data storage, data dump and database management.
High detection accuracy
In terms of voltage detection, BMS adopts a floating voltage detection structure and a dedicated dual-integrator ATD chip, which fully considers the impact of the AC ripple of the power grid during charging, effectively solves the problem of common ground, avoids cumulative errors, and improves the accuracy of voltage detection. Reaching 0.5%; in terms of temperature detection, the scalability of the temperature sensor is fully considered while ensuring that the temperature error is within the range of ±0.5°C; in terms of current detection, full-range, equal-precision sensors and high-precision dedicated integrated chips are used , to meet the needs of current detection and energy accumulation, making the current detection accuracy reach 0.5%.
Simple interface
In order to facilitate users to use, BMS has simplified the external output interface while ensuring the above functions. The external connection only includes power lines and communication lines.
Complete auxiliary equipment
In order to simplify the user's operation and enhance the intuitiveness of the system, the battery management system has designed a portable fault diagnosis and data storage instrument to realize fault diagnosis and location, greatly enhancing the ability to solve battery faults on site.
Humanized PC monitoring interface
BMS has designed a corresponding PC monitoring interface, which can realize functions such as online monitoring of BMS data, data dump, database management and data analysis, and battery performance analysis.
High security, reliability and stability
The system uses advanced technologies such as large-scale integrated circuits, filtering, high-level isolation, and data redundancy, combined with actual demonstration operation experience, to ensure the safety, reliability, and stability of the system.
Engineering design In order to meet the needs of the vehicle's harsh operating environment, BMS adopts a waterproof and dustproof design, including component selection, chip direct sales manufacturer research, sample testing, system high and low temperature cycle aging, circuit board testing, product factory inspection, and on-site testing. Strict control and recording mechanisms are implemented in other aspects to ensure the quality of the product, and the professional wiring and post-maintenance team ensures the efficient operation of the vehicle.
