Ecoult UltraFlex

The UltraFlex is a 48 V battery bank & BMS provided by Ecoult. The technology is considered to be   advanced lead-acid  because the negative electrode of a traditional lead-acid battery is enhanced with a carbon treatment to create an ultracapacitor within each cell that changes the chemistry and performance to allow the battery to operate in continuous partial SOC, where internal resistance is lower. The UltraBattery technology was invented by Australia’s CSIRO and is now commercialised by Ecoult in Australia, Furukawa Battery Company in Japan, and East Penn Manufacturing in the US. The batteries for the UltraFlex system are manufactured in East Penn’s manufacturing plant in Pennsylvania and the BMS, software and racking is designed and made in Australia.

The unit is connected to an SMA Sunny Island inverter that will charge/discharge the batteries.


Testing update: The UltraFlex has been taken offline while Ecoult investigates apparent reduced capacity in 3 out of the 8 batteries used at the ITP test centre.  At this stage no cause has been identified and the affected batteries have been sent for a detailed engineering investigation at the manufacturing facility in the USA.
