As India’s EV growth exposes a hidden chip gap, startup MOSart Semi steps in, aiming to fix it with a homegrown battery-management semiconductor for next-generation mobility.
Bengaluru-based startup MOSart Semi is developing an automotive-grade battery management system system-on-chip (BMS SoC), a semiconductor designed to manage, monitor, and protect electric vehicle (EV) batteries through a single integrated chip.
The company’s chip combines sensing, diagnostics, safety monitoring, and control functions that are typically handled by multiple electronic components inside an EV battery pack. By consolidating these functions into one programmable semiconductor, MOSart Semi aims to simplify battery electronics while reducing system cost, weight, and engineering complexity for manufacturers.
Meanwhile, India’s electric vehicle market is projected to cross 10 million annual unit sales by 2030, sharply increasing demand for automotive semiconductors. Battery packs account for 30–40% of the total EV cost, and the electronics that govern them directly influence safety, charging performance, and battery lifespan.
Despite this strategic importance, India relies almost entirely on imported battery management chips supplied by global semiconductor companies. Supply disruptions during recent chip shortages exposed how dependent domestic automakers remain on overseas components.
As vehicles transition toward electrified and software-defined architectures, battery intelligence is emerging as a critical technology layer, creating an opportunity for locally designed semiconductor solutions.
Traditional battery systems use several discrete integrated circuits connected through complex wiring networks, increasing validation timelines and development costs. MOSart Semi’s BMS SoC replaces this multi-chip architecture with a unified platform capable of delivering current-sensing accuracy of around 0.1% and voltage-measurement precision below 0.5 millivolts, performance levels required for safe EV deployment.
The chip allows automakers to run proprietary battery algorithms via an onboard microcontroller and memory, enabling compatibility across lithium-ion, lithium iron phosphate (LFP), and emerging battery chemistries. This programmability allows manufacturers to customise battery behaviour without redesigning hardware.
The company is targeting battery platforms above 3 kWh, spanning electric two-wheelers, passenger vehicles, commercial fleets and stationary energy storage systems; segments expected to support India’s electrification and renewable expansion.
As EV adoption accelerates and semiconductor self-reliance remains a policy focus, MOSart Semi reflects early efforts to address gaps in domestic automotive electronics, particularly in battery management systems.
