Battery pack online balancing system

Battery pack online balancing system
The
Battery pack online balancing system produced by Shanghai Shunmeng Electronic Technology Co., Ltd.
makes full use of contemporary advanced embedded computer technology and real-time Ethernet communication technology , realize the detection of battery cell voltage, internal resistance, battery pack total voltage and other parameters, and can realize battery online balancing adjustment control to avoid battery overcharge and undercharge. The system consists of a monitoring host
, a single battery voltage internal resistance acquisition module
, and a voltage internal resistance equalization module
. Expandable real-time monitoring of the operating status of the DC power supply system (charger working status, module fault status, AC status, grounding status, fuse fuse, arrester failure and other important parameters). The monitoring terminal at each power supply end connects the voltage acquisition and equalization modules together through the bus. , collect all their signals together for unified management, and transmit all the collected information to the central server through the optical fiber LAN port or the free serial port of the optical transceiver. The server software stores and manages the information and can distribute the information to each relevant management position. Computer, so that every computer on the LAN can browse all operating data and alarm information. The system monitoring software provides hierarchical management passwords and permissions, and can change the information and parameters of any power supply.

Performance characteristics and indicators
1. System characteristics
The system adopts segmented small current discharge method to test the internal resistance of the system without injecting any signal into the system. The test time is short and there is no need to change the DC main circuit. It has extremely low impact on the system voltage, and with high-precision voltage detection, accurate internal resistance testing can be completed online.
The system fully considers various indicators, connection line short-circuit protection, multi-layer isolation and other reliability designs.
Each system Each acquisition module can accurately patrol and test the battery voltage, and the voltage resolution can be as high as Automatic balancing of battery voltage management and other functions.
All internal switches use solid-state switches instead of relays, with no arcing, no open flames, and no life problems.
