Why choose Eatron's BMSTAR?
Eatron is an expert team with a strong history of delivering products to leading OEMs and Tier-1s, including NIO, Vinfast & Knorr-Bremse for serial production. Eatron’s innovative software platform enables automotive and mobility OEMs and Tier-1s to rapidly integrate Eatron’s offerings for serial production. With our hardware agnostic software platform built on physical models, we give you the edge you need to make you a leader in the development of software defined mobility.
BMSTAR’s software component at the edge is designed to have a cloud counterpart with integrated connectivity and analytics. These enable over-the-air updates, as well as continuous and adaptive software improvements to achieve superior performance and reliability (e.g. for SoC/SoH) over the lifetime of the vehicle.
This is achieved via physics-based algorithms and AI powered software functions – for both low-voltage (LV) and high-voltage (HV) BMS.
150+
combined years of BMS development experience.
High SOX accuracy
Calculation of state of charge, power, health & energy.
Fast time-to-market
Highly configurable software platform developed for serial production.
Optimum security
Complies with ISO26262, ASPICE, ISO21434 & ISO9001.
Optimale Leistung
Adaptive advanced controls functions, over-the-air updates & data analytics functions running on the cloud.
