Portable Smart Lithium Battery Packs
Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery in which the cathode (positive electrode) contains lithium, and the anode (negative electrode) is made of a type of porous carbon.
Lithium-ion batteries are common in portable consumer electronics because of their high energy-to-weight ratios, lack of memory effect, and slow self-discharge when not in use. In addition to consumer electronics, lithium-ion batteries usually integrated in packs of several cells, are increasingly used in defense, automotive, and aerospace applications due to their high energy density.
However, certain kinds of mistreatment may cause conventional Li-ion batteries to explode. For this reason it is necessary to design an adequate battery management system which ensures the protection and control of the battery pack.
Environmental and operating conditions are a crucial point in the life of a battery pack. Temperature, humidity or marine environment can drastically decrease the battery life time and performance.
GENPORT has an equipped electrochemical, electronic and mechanical laboratories to engineer custom Smart Lithium Rechargeable Battery Packs based on wide variety of chemistries, 30.000 high power density Lithium cells, a proprierty Battery Management System (GenBMS), providing battery monitoring, high-precision fuel gauging, battery diagnostics and battery-to-host communications.
A Battery Management System (BMS) is an electronic control system that manages safely and efficiently a rechargeable lithium battery pack. Its main function is to track the State of Charge (SoC) and State of Health (SoH) of the battery pack, as well as perform maintenance actions such as cell balancing to provide maximum lifetime for the pack. Moreover It must monitor the main variables of the pack to avoid any possible overheating that can cause explosions.
GenBMS is a Battery Management System designed for Li-Ion and Li-po battery packs from 2 to 4 series cells and with a maximum inrush current of 12A.
Made of the experience of Genport, GenBMS is able to provide all the safety protection: over current, over / under voltage, over temperature and short circuit.
Thanks to the Texas Intruments’s IC on board, GenBMS is fully compliant with the SMBus ver. 1.1 which enable it to dialog with the host system. The Impedance Track algorithm implemented can also guarantee SoC estimate error less than 1% thru the entire lifetime.
