VARTA has developed 3 series of Lithium-Ion batteries, the EasyBLock, EasyBlade and EasyPro models. These ASBs communicate with CAN-bus (CANopen), and can be connected parallel up to 25 modules. This modular setup allows for a flexible energy capacity that ranges from 0.58kWh to 37.5kWh.
Which technology to choose?
Lithium-Ion is a catch-all for a range of battery chemistry variants. NMC (Nickel Manganese Cobalt) and LFP (Lithium Iron Phosphorus) are prominent Lithium-Ion battery types today. VARTA’s EasyBlock and EasyPro series use Lithium Iron Phosphate (LiFePO4), while the EasyBlade series utilizes Lithium Nickel Manganese Cobalt Oxide (NMC). Selecting between LFP and NMC batteries ultimately depends on the application requirements, including safety, energy density, cost, and environmental impact.
Key differences between NMC and LPF
