Battery online balancing device

Battery online balancing device
The
battery online balancing device produced by Shanghai Shunmeng Electronic Technology Co., Ltd. makes full use of contemporary advanced embedded computer technology and real-time Ethernet communication technology to achieve Detection of battery cell voltage, internal resistance, total battery pack voltage and other parameters, and can realize online balance adjustment control of the battery to avoid over- and under-charging of the battery. 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 pair. The impact of system voltage is extremely low, 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 The acquisition module can accurately patrol and test the battery voltage, and the voltage resolution can be as high as Balanced battery voltage management and other functions.
All internal switches use solid-state switches instead of relays, so there is no arcing phenomenon, no open flames, and no life problems.
