Why lithium?
High quality 12 V Lithium Iron Phosphate (LiFePO4) cells are the basis for WhisperPower’s new lithium storage systems. The new lithium Power Plus Battery Racks are a sustainable and highly energy dense solution to store electrical energy for use “on demand”. Due to the specific characteristics of the Whis- perPower LFP ferro lithium batteries, the battery pack(s) can be charged and discharged at high amperes.
The added value of WhisperPower
All Lithium battery solutions can be supplied just “as a bat- tery”. However, we offer our customers a total solution that eliminates the risk of the user’s battery not being charged, discharged or monitored properly. The system approach goes beyond simply supplying a WhisperPower battery charger or combination inverter/charger. If required, we can supply a complete diesel fuel based fast charge system in combination with the Lithium Power Plus rack with integrated BMS, DC bus bar (s) distribution including fuses and an advanced monitor- ing system that monitors the behavior of the cells inside the battery down to the cell level: WhisperCare.
Sustainable and cleaner for the user
Further electrification to replace or supplement fossil power solutions reduces the carbon footprint on a substantial basis. In addition, large cost savings can be achieved because the fossil power system can be used much more efficiently.
A higher upfront investment is recouped within a short time.
