CAN Network Optimization for Energy Storage Batteries

CAN isolation bridge product has 2 electrically isolated CAN bus interfaces, which can realize the relay function of CAN-bus network. ID and data conversion can be effectively realized by increasing load nodes, extending communication distance, and infinite cascading. It can solve the multi-node networking fault of CAN bus in the energy storage battery management system.

Features of CAN FD isolation bridge

• This product can increase load nodes, extend communication distance, and expand network relay.
• The communication Baud rate of each channel can be configured to realize CAN/CANFD network interconnection with different communication Baud rates.
• It has powerful functions of ID filtering and data conversion, accurately inspects and accepts ID configuration, and reduces the load of CAN bus. Or it changes the specific ID and data to achieve the goal of removing interference data and distinguishing different devices.
• It has strong anti-interference capability and prevents user’s devices from being disturbed and crashing.

Extension solution of serial devices for energy storage system

As there are many peripherals in energy storage containers and a large number of serial devices (such as electricity meter, sensor, cooling system, etc.), the number of serial ports of local controllers is often insufficient. In view of this demand, Zhiyuan Electronics can provide 2-channel and 8-channel serial server products to solve the problem of insufficient serial ports of energy storage units.
