The module supports comprehensive analytics, specifically estimating SOC (State of Charge), SOH (State of Health), SOE (State of Energy), and SOP (State of Power). Crucially, the SOC and SOH values can be accurately estimated for both individual cells and the overarching pack.
The dual-network port cascading function is designed to enable seamless communication between the main control and ESMU/ESCCU. Additionally, it facilitates communication directly between multiple main controls.
The module supports terminal current detection by utilizing a hall sensor, which allows for real-time isolation of current DAQ (Data Acquisition) and processing.
Yes, the battery system insulation detection function is highly configurable; it can be set on or off strictly according to your system configuration requirements.
