Battery Systems

Battery Architecture & System Design

​

Battery performance, safety, cost, and long-term risk are defined at architecture level.
We support battery system definition with a cell-to-pack perspective, aligned with vehicle integration, safety, and lifecycle constraints. Typical scope includes:

​

• Cell selection and application engineering

• Chemistry, format, and supplier trade-off analysis

• Module and pack mechanical design direction

• Structural concepts, enclosure design, and crash considerations

• Thermal management architecture and cooling strategy

• Battery electrical architecture definition

• High-voltage topology, protection concepts, and current paths

 

The objective is system coherence and defensibility, not isolated component optimization.

​

​

BMS Software Engineering

​

Safety-critical battery control software, developed and elevated to global automotive standards.

​

eMOBINO delivers full-scope BMS software engineering for automotive traction batteries, covering architecture, core functionality, functional safety integration, and verification-driven development.

​

​

Software Architecture & Core Control Logic

​

We design modular, scalable BMS software architectures aligned with OEM practices and AUTOSAR-oriented environments.

Typical functional scope includes, but is not limited to:

​

• System and software architecture definition

• State and initialization management

• Cell monitoring, diagnostics, and balancing logic

• Thermal management and protection strategies

• State estimation algorithms:

  • State of Charge (SoC)

  • State of Health (SoH)

  • State of Function (SoF)

  • State of Power (SoP)

• Energy and power management logic

• Contactor and high-voltage control

• High-voltage measurement handling

• I/O abstraction and hardware interaction layers

• Communication management (vehicle and external interfaces)

• Error, warning, and fault handling strategies

• Calibration and parameter management

• Task scheduling, integration, and runtime performance optimization

 

The focus is always on robust behavior under real-world operating and fault conditions, not only nominal use cases.

​

Verification-Driven Software Development

​

Verification is treated as a core engineering activity, not a downstream checkbox.

We define and execute structured verification strategies across multiple levels:

​

• Simulation-Based Verification (MiL / SiL)

• Definition of unit-level and integration-level test cases

• Preparation of simulation environments

• Functional verification of core algorithms

• Fault-injection-based robustness testing

• Verification of safety mechanisms and monitoring logic

Hardware-Based Verification (Customer HW / Partial HiL)

• Test case definition and test setup preparation

• System initialization and boot-up behavior validation

• Communication and interface verification

• I/O handling and contactor management tests

• Basic functionality and degradation behavior tests

• Error and warning handling tests based on fault injection

 

Test results are not only executed, but interpreted, with findings fed back into design correction and elevation.

​

​

​

BMS Hardware Engineering

​

We support BMS hardware design and design elevation with a strong emphasis on functional safety, diagnostics, and production robustness.

Scope includes:

​

• BMS hardware architecture definition

• Safety-critical measurement and signal paths

• Redundancy and diagnostic concepts

• HV sensing, isolation monitoring, and protection circuits

• Review of existing BMS hardware designs

• Design elevation toward ISO 26262-aligned architectures

 

This service is particularly valuable for organizations with existing designs that must be upgraded to global OEM safety expectations.

 

 

 

Functional Safety Integration (ISO 26262)

​

Functional safety is embedded across battery system, BMS hardware, and BMS software.

Our role focuses on direction, integration, and design elevation, not document-only compliance.

Typical scope includes:

​

• Translation of functional safety concepts into system and software requirements

• Guidance for implementation of safety mechanisms

• Safety monitoring and diagnostic strategies

• Definition of functional safety test cases

• Functional safety verification in simulation environments

• Alignment with vehicle-level safety concepts

 

This ensures battery systems are defensible under audits, certification, and field incidents.

​

​

​

Integration & Vehicle Interfaces

​

Battery systems must integrate seamlessly into the vehicle platform.

We support:

​

• Pack integration into vehicle architecture

• Mechanical, electrical, and thermal interface definition

• HV interfaces and safety concepts

• Alignment with vehicle E/E architecture and control systems

​

​

​

Validation, Safety & Compliance Direction 

We design validation strategies, define acceptance criteria, and interpret results.

Battery-specific scope includes:

​

• Automotive battery DVP strategy definition

• Abuse scenario definition and test strategy direction

• Selection of test methods and standards (directional)

• Interpretation of test results and readiness assessment

• Battery safety analysis and failure interpretation

• Certification readiness direction
  (e.g. ECE R100, UL 2580, UN 38.3 – directional)

 

This capability is critical for organizations preparing for SOP, certification, audits, or post-incident investigations.

​

​

​

Design Review & Design Elevation

​

Beyond greenfield development, eMOBINO provides independent third-eye reviews of existing battery systems.

This includes:

​

• Architecture and design gap analysis

• Identification of safety, robustness, and scalability risks

• Design elevation toward global OEM standards

• Clear, actionable recommendations with implementation paths
