Smart Battery Systems (SBS) is a branch and an important part of modern power technology. Smart battery system function to measure, calculate and store battery data through internal electroni ed in every aspect, including product R&D, supplier management, material control, product process control, finished Shipping and after-sales service.
Smart battery management system
We adhere to the customer-oriented requirements, to provide customers with satisfactory products with pragmatic and rigorous attitude, to provide customers with products beyond the expectations with innovative technology and craftsmen spirit.ont-size:12px;">

Battery parameter acquisition mainly includes the collecterred to as the delay time and the lowe #`| ( ( Xe| j" j" Y" T" S" T" T" g| j" j" ion of single cell voltage, the system current, the system temperature, which can be used to judge the battery remaining power, and fault protection. Voltage of Lithium-ion battery reflects the performance of the battery, both for protection of overchargeFeatures:
High and stable operating voltage: standard voltage is 3.6V and the operating voltage throughout the life of the period to maintain a significant stable.
Better storage life and reliability: with low self-discharge characteristics, the annual self-discharge rate 2%, while its use of stainlesnly to prevent the battery from over-temperature, which leads to security incidents, and compensate for the remaining capacity calculation. The remaining power is an important parameter to reflect the performance of the batteryits also the basis judgmn mercury, cadmium, lead and other heavy metals, no environmental hazards.
Good sealing performance: Li-SOCl2 battery is fully sealed battery. The battery cover is welded to the battery casent for main engine of charge, discharge. Accurate estimation of the remaining power can protect the battery, to prevent overcharge, over discharge occurs, to facilitate customers to make a reasonable time schedule.
We will further optimize and standardize the management system, and continuously improve quality and servi:justify;">

When using a lithium-ion battery, a battery pack failure protection should be provided, overheating or overcharge, which may cause fire or explosion. Smart battery management system concludes of primary protection and secondary protection. The primary protection detects the current, voltage and temperature and the remaining power , In order to balance the charge and discharge, to proteso as identify if any dangerous such as overcharge, over discharge, over temperature, over-current and short circuit occurs, and then shut down corresponding, to protect battery pack from damaging. Secondary protection functions as backup protection in cadiv>

SMBus Communication Functions
a package case, among them, the cell protection control circuit works as a guardian to support the entire intelligent battery system management, which is called SMBus (System Management Bus). The communication function of battery packs mainly rely on the

Cell balance
Due to the limitation of lithium-ion battery production technology, as well as the influences of discharge rate and temperature on battery, there are differences in voltage, internal resist1`| i| @i| @gy l| i| i| i| 2`| h| h| @Fy h| 2`| h| h| y 0l| `h| 2`| h| @h| y xl| h| 3`| f| `f| 0y @f| 4`| pi| pi| y pi| pi| k| k| k| Hk| Hk| Hk| Hk| k| k| k| k| k| k| k| k| 8k| 8k| 8k| k| k| k| k| k| k| k| k| k| k| k| ance and capacity between the individual cells in the battery pack, and the differences become more obviously after several cycles, which leads to the average cycle life of battery becomes much shorter than single cell. Meanwhile, since lithium-ion batteries require much strictly on charge and discharge, when overcharge, over discharge, overcurrent and short circuit, etc. The internal heat increased significantly, which prone to spark, burning or even explosion, cell balanced measures must be taken to ensure safety and stability.
SMBus communication
The system management bus (SMBus) is a two-wire interface to ensure the communication between equipment and other parts of the system. SMBus provides a control bus for system and power management related purpose based on I2C operating principle. A system can communicate with multiple devices without the adoption of independent control lines. The intelligent management system needs to provide
SMBus, wire to host to read the conversion data and status, and control the intelligent battery management system according to the requirement of host.
