Sileaf’s Advanced Storage system

Ever since its inception, Sileaf has been at the forefront of the Indian energy landscape developing innovative robust and reliable products. Sileaf’s R& D team has over 6 years of experience and efforts building robust solar products made in India for Indian environment and has developed a range of innovative products including solar DC water pump, off-grid inverter, string inverter, data logger and power management controller (DG controller orreverse power controller).

In January,Sileaf launched its indigenous advanced storage solution with Battery Management System(BMS). The system uses advanced Lithium-Ion (Li-Ion) batterieswhich ensure long life, minimum maintenance and space requirement and substantially lower losses than conventional batteries.

The BMSmanages the battery, protecting it from operating outside its safe operating area. It’s developed indigenously for monitoring cell voltage, pack voltage, and pack temperature of Li-Ion battery with automatic cell balancing for each cell in order to maintain certain voltage.The system has independent cell voltage, temperature protection and cell balancing. Intelligent, efficient multi-cell balancing maximises the usable range
of the battery and improves the life of battery pack.

The controller is designed using high-end Micro-controller which provides the complete range of programming and diagnostic features that increase the flexibility of the system. The BMS offers custom configuration for setting the limit and interlocks which protects the battery. Cells are protected from over-voltage, under-voltage, over-current, over-temperature, and under-temperature based on the programmed minimum and maximum values in the battery profile.It also integrates a voltage translation and precision analog-to-digital converter system to measure battery cell voltages with high accuracy and speed.All cells are connected in a daisy chain configuration which provides scalability and simplicity of the system.
