240V 50A Battery Management System BMS for Solar UPS ESS

What? Why? How?

High voltage bms is to make many cells in 8 strings, 12strings 13strings...24strings to be a basic module, and many same battery modules in series as a battery rack and many racks in parallel as a battery stack and many stacks in parallel as a battery bank and...

GCE says, we can make 8 strings of cells, 12S ,13S...23S, 24S, any of them as a basic module, you many install a mosfet bms(low volatge bms or Xs bms) into the basic battery module(20Kwh maximum) as an independent system, I guess you're all too familiar with it. Now, i want you to make each all same modules in series to get 200kwh or more. You will quickly think of making all modules inparallel, right? but this is not a good solution. It's neither efficient nor perfect. Please discard it to the Pacific Ocean.

GCE has R&D high voltage bms for nearly 10years, we have 3-level structure of BMS with perfect solution for basic battery modulesin series and parallel to make 100kwh to 1Gwh or more. please refer to the picture, we install BMU(slave bms) into the basic battery modules, each module is connected in cascade by Isolated CAN bus wire harness till to RBMS(rack bms /master bms). BMU collecting voltage, and temperature from each cell of modules. The voltage balance between battery modules can be achieved by starting the fan or balancing the resistance. We can set the ID number of each RBMs through the dial switch, and make each RBMS in parallel by network cable. We use Stack BMS collecting all information from each RBMS. GCE has rich interface reservation and is very friendly to the access of external systems.The core technology of GCE is to ensure stable, efficient and reliable system communication.
