Shenzhen Billey Electrics Company Limited

we had already launched 48V Smart-Li (just after Huawei, ZTE), and it has been applicated by China Tower. The function and application can be satisfy: 1, The site backup power expansion: by the mix used with Lead-acid battery in parralell. 2, The site energy storage: off-peak power consumption and peak-shaving by the Smart-li operation mode. (1) Safe and reliable ●The intelligent lithium battery Pack has built-in aerosol fire fighting module for precise fire fighting ●Double-layer isolation between battery and inverter ●With input and output over-voltage, over-temperature, short-circuit and other protection functions (2) Flexible adaptation ● Support any parallel connection of old and new battery packs ● Support parallel connection of battery packs of different capacities ●Support any parallel connection of different types of batteries (lead-acid, conventional battery pack, ladder battery pack) ● Support on-demand phased expansion (3) Intelligent management ● Support "one-button" automatic startup ●Support independent control of output voltage and current, control of circulating current/bias current phenomenon ● Support automatic balance between battery packs ●Support local and online upgrade The EnerSmart Telecom Li-ion Battery (EnerSmart Li) is designed for various 48Vapplication scenarios, and it is composed of prismatic LFP cells, intelligent battery management system(BMS), and bidirectional DC converter(BDC).The product features active control of the charge and discharge voltages to solve the bias current and circulating current issues inside battery packs when connected in parallel. Moreover, this product allows for mixed use of lithium and lead-acid batteries and can be used for smart peak shifting and off-peak power consumption to save customers' initial investment and thus enhance the income on investment.
