Unlock Strategic Advantage with In-House BMS Technology

IP Control and Differentiation

• Full control over software and hardware allows OEMs to build differentiated and IP-protected solutions.

Software is the Core Value Driver

• The majority of BMS value lies in its software, including algorithms for SoC, SoH, balancing, and safety logic.
• Off-the-shelf BMS vendors embed the cost of software development into every unit, driving up the product price.

Customization for Specific Battery Architectures

• Tailored support for unique cell chemistries, pack geometries, and cooling strategies enhances performance and safety.

Battery Life and Performance Optimization

• True optimization of battery lifespan, charging profiles, and energy throughput is only possible with deep control over the BMS software.
• Allows implementation of proprietary charging strategies, balancing routines, or degradation models.
•  

Integration with VCU / EMS and System Controllers

• Easier and cleaner integration with vehicle control systems, energy management platforms, or predictive maintenance services.

Faster Iteration and Innovation

• Shortens development cycles and enables fast reaction to field data or customer feedback.

Regulatory and Functional Safety Compliance

• Owning the software stack simplifies audits and functional safety validation to ISO 26262, UL 1973, AIS-156, etc.

Lifecycle Management

• Enables long-term firmware support without dependencies, platform component re-use across generations, and control over obsolescence.

Cybersecurity and OTA Capabilities

• Secure key management, firmware signing, and OTA updates are easier to implement and verify in-house.

Cost Optimization at Scale

• Eliminates perpetual license or per-unit fees.
• Enables lean hardware design with just the required features, avoiding over-specs dictated by third parties.
•  

Supply Chain Flexibility

• Enables sourcing hardware from multiple vendors while maintaining a consistent software platform.

Enhanced Field Diagnostics

• Access to specific internal telemetry, logs, and software stack improves fault isolation and optimal customer support responsiveness.
•  

Avoiding Vendor Lock-In

• Eliminates risk of BMS vendors changing business models, pricing, or disappearing from the market.

Better Margin Control

• In-house development avoids double-markups and allows OEMs to capture more of the product value chain.

Internal Capability Building

• Fosters a knowledge-rich engineering team and builds long-term competitive advantage in battery-centric design.

Readiness for AI and Data-Driven Enhancements

• Proprietary software stack becomes a foundation for integrating edge analytics, ML-based SoH estimation, and adaptive algorithms.

Strategic Technology Positioning

• A proprietary BMS platform forms the foundation for battery intelligence, digital twins, and AI-enhanced lifecycle tools.

Investor and Market Perception

• In-house BMS capability signals technical depth, strategic autonomy, and IP leverage -important for valuation.

Customer Trust and Brand Identity

• OEMs with in-house BMS can better control end-user experience, diagnostics, and reliability expectations.

Customization as a Differentiator

• Ability to offer tailored features per customer segment or application niche (e.g., fast-charging fleets vs. long-life ESS).

Dynamic operational boundaries: Every BMS ensures the battery stays within the safety window of voltage, current, temperature, etc… But dynamic operational boundaries are the key to strategic battery lifecycle management -they bridge the gap between chemistry limits and application demands.

• Examples are chargelimit to 80%SOC,adaptive SOC limit, DOD limit, limit fast charge current in cold weather, operational temperature window, geofenced parameters, etc…

Using the BMS not just as a safety device but as a battery longevity optimizer justifies a more sophisticated, insourced BMS strategy.

• These boundaries can be dynamically adjusted per application (e.g., urban vs. highway traffic) and even over time (adaptive BMS strategies).

These boundaries also allow for differentiated warranty strategies, e.g., guaranteeing longer pack life under tighter constraints for high-value customers.

• Application-based optimization can increase battery life by 200%.

Cell Chemistry-Specific Optimization: Different chemistries (e.g., LFP, NMC, LTO) respond differently to high C-rates. An OEM-owned BMS allows for custom profiles that match the exact chemistry and application.

Pre-conditioning Logic: Efficient fast charging often requires pre-heating or cooling the pack to a target temperature range. This orchestration between the thermal system and charger requires tight BMS control.

Charge Curve Shaping: Fast charging isn’t just about pushing high current. It’s about shaping the voltage and current curve to minimize degradation -this logic lives in the BMS.

Charger Communication (DC fast charging standards): Full control over protocol layers (e.g., ISO 15118, CHAdeMO, GB/T, CCS) and the ability to respond to charger-side requests is much easier with an insourced, modifiable BMS.

800V drivetrain: Supporting high-voltage safety, precision, and performance through complete system integration and control.

Standardisation across vehicles–one platform and software stack for all vehicles with strongly reduced supplier & licensing overhead. Saves on certification, ensures fleet-wide data consistency and streamlines after-sales service.
