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.

最適なパフォーマンス

Adaptive advanced controls functions, over-the-air updates & data analytics functions running on the cloud.
