introduction 
    Anytime lithium cells are connected in series to make higher voltage battery packs, as is the case in electric vehicle applications, the usable capacity of the entire pack will only be as much as the capacity of the lowest cell. Even if a battery pack is well-matched when new, imbalances between the cells will occur over time. The primary function of a Battery Management System (BMS) is to facilitate equalization at the module or individual cell level so that the entire battery pack has as much useable capacity as possible. The other benefits of the GBBMS digital BMS line of products is rapid monitoring of individual cell voltages and temperatures. There are a variety of free software options comes with BMS which allow for a clear visual display of the battery and cell data. With high accuracy and easily programmable high and low voltage set points the GBBMS is an exceptional solution for many electric vehicle lithium battery packs, stationary power supply packs and also for battery testing. Connecting to the BMS with any Windows/Linux/Mac/Android based computer is easy with the Optional CAN2Ethernet Dongle. The optional Diagnosis system allows for an independent in-dash touch screen solution. This device  manage 18 cell per module with passive balancer . All of the BMS units use an intuitive command structure and are very simple to set up. Real-time status LEDs on the boards themselves indicate high and low conditions as well as which cells are full (when dissipating energy during equalization). Specific historical data of maximum voltage high and low points are stored in the BMS unit's internal memory and can be easily viewed the graphical User interface on the PC. This have master central unit with high precision current measurement, protocol conversation, SOC estimation, onboard real time logger, protection outputs and mode manager and calibration inputs.
