Poland and EVE Energy have entered into a long-term strategic cooperation focused on battery systems for electric commercial vehicles, including buses.
The first result of the partnership is VERSORA LMFP, a new version of BMZ’s modular battery platform using lithium manganese iron phosphate chemistry. Presented at IAA Transportation 2026, the technology is positioned between conventional LFP and NMC solutions.
The companies aim to combine some of the cost, safety and cycle-life advantages of LFP with improved energy density, charging performance and cold-temperature capability.
According to EVE Energy data presented at IAA Transportation, an LMFP battery system can be up to 10% lighter than an equivalent LFP system for the same energy requirement in a long-haul truck application.
The company also states that LMFP supports charging at up to 1 MW and 2.2C, enabling a 10–80% state-of-charge increase in less than 25 minutes.
The technology is specified for more than 4,500 cycles to 80% state of health at 100% depth of discharge, while the target for the next generation is above 5,500 cycles.
Cold-temperature performance is another focus. EVE Energy states that LMFP retains around 85% of its capacity at -20°C, compared with approximately 75% for conventional LFP.
VERSORA is designed as a modular battery architecture that can be adapted to different vehicle types and installation spaces.
Its Compact and Versus modules can be installed in locations including the floor, body and roof, making the architecture particularly relevant for electric buses where packaging flexibility is important.
VERSORA NMC and VERSORA LMFP are designed with the same dimensions and weight, and use the same mounting space, electrical interface and voltage classes.
This allows vehicle manufacturers to offer different battery chemistries within the same vehicle architecture without redesigning the complete battery installation.
VERSORA NMC samples are already being supplied to selected BMZ customers, with series production scheduled to begin in 2027.
The LMFP version remains under development. First customer samples are planned for 2027, followed by series deliveries from mid-2028.
For bus manufacturers, the modular approach could provide greater flexibility to select battery chemistry according to vehicle range, charging strategy, operating climate and cost requirements.
