Product overview:
Han yu is a master of the distributed BMS lithium battery management system, which adopts the principle of a multi - from architecture, and applies a number of invention patents in strict accordance with the ISO26262 development process. It is compatible with the AUTOSAR standard and supports the RTM system. The whole series of products are made of automobile grade components, compact size, excellent performance, meet ISO26262 standard, high performance CPU, and convenient system expansion and upgrade. At the same time, han yu's unique long - scale anti - attenuation technology is the long life of electric vehicle power system, high reliability.
● Active/hybrid/passive equilibrium BSU, main from the architecture;
● Severe automobile test, EMC, vibration resistance and other indicators exceeded the national standard to ensure the safety of the vehicle;
● Built-in large-capacity FLASH, BMS real-time data is also stored in local FLASH through wireless transmission, and reliable recording of the important operational status data of BMS, so as to facilitate the traceability and analysis of the operation process of the battery;
● Accurate and efficient SOC calculation algorithm, SOC calculation is more accurate, and the error can be controlled within 5%;
● Distributed BMS is applicable to pure electric, plug-in, plug-in and hybrid vehicles.
