Core BMS Functions We Develop

Our BMS solutions deliver five essential functional domains.

Cell Monitoring & Protection

Our BMS platforms provide high-precision cell voltage, current, and temperature monitoring with real-time fault detection and protection mechanisms. The system supports millivolt-level voltage accuracy, bidirectional current sensing up to ±500A, multi-point thermal monitoring, and ultra-fast protection response for overvoltage, undervoltage, overcurrent, overheating, and short-circuit conditions to ensure maximum battery safety and reliability.

Intelligent Cell Balancing

We develop both passive and active cell balancing solutions to maintain uniform charge distribution across battery packs.

Our active balancing architecture efficiently transfers energy between cells with minimal power loss, improving battery lifespan, charging performance, thermal stability, and overall energy efficiency for EV and high-capacity energy storage applications.

State Estimation Algorithms (SoX)

Advanced algorithms provide accurate knowledge of battery condition:

ParameterFull FormTypical AccuracyPurpose
SoCState of Charge±2-3%Remaining energy (fuel gauge)
SoHState of Health±3-5%Capacity fade (end-of-life prediction)
SoPState of Power±5-10%Max charge/discharge current capability
SoEState of Energy±3-5%Remaining usable energy in kWh

Our estimation engine uses Extended Kalman Filters (EKF) and machine learning models that combine physics-based electrochemical models with neural networks that learn to correct model residuals or capture parameter drift over time. The algorithm automatically adapts to cell chemistry (LFP, NMC, LTO, Sodium-ion) and operating conditions.

Thermal Management

The intelligent control of the system includes cooling liquid, controlling fans, controlling refrigerant valves, and controlling battery heating mechanisms while monitoring the temperature differences between cells in order to identify abnormal behavior, whether cooling failures or potential internal fault; before these faults reach critical levels.

Communication & System Integration

Support for a number of different industrial communications interfaces such as, CAN bus, RS-485, Modbus RTU, SPI, I²C, BLE 5.0, Wi-Fi, and 4G/LTE provides the opportunity to connect seamlessly to EV controllers, inverters, EMS platforms, mobile diagnostic applications and cloud solutions to allow for dependable real-time data communication and remote monitoring.

Popular Global Technology Partners & SDK Integrations

We're experience in integrating third-party IoT devices, business management software, and enterprise SDKs into custom software.

Our team has worked with world-famous battery manufacturers, EVs, and Industrial IoT companies to create connected platforms, Cloud dashboards, mobile applications, telemetry systems, and remote monitoring solutions.

Some of the popular global platforms and BMS brands we frequently integrate into our systems include:

Custom Hardware and Firmware Development

Off-the-shelf BMS modules rarely match the exact voltage, current, safety, or communication requirements of a specific application. We design custom BMS hardware from the ground up or adapt reference platforms to your exact specifications.

Hardware Design Capabilities

Our engineering team develops complete BMS hardware solutions using automotive and industrial-grade components including Infineon AURIX™, NXP S32Kxx, STM32, and ESP32 MCUs. We integrate high-accuracy AFE chips, isolated DC-DC power systems, high-voltage contactors, smart fuse protection, and digital isolation technologies supporting up to 1500V systems with reliable diagnostics, safety, and communication isolation.

Firmware & Software Development Stack

Our BMS firmware stack is built using C/C++ and Rust for safety-critical applications, running on FreeRTOS or Zephyr RTOS with deterministic real-time control loops. The platform includes HAL drivers, SoX estimation algorithms, thermal and cell balancing logic, secure AES-256 authenticated bootloaders, rollback protection, and advanced diagnostics including BIST, watchdog monitoring, and fault detection systems.

Designing for Manufacturing (DFM)

We deliver BMS Designs that are ready for production along with a full set of documentation to ensure production runs smoothly, including a Bill of Material, Gerber Files, Assembly Instructions, Testing Procedures, and Flashing Tools - allowing our clients to produce products with established contract manufacturers.

Battery Management Monitor Mobile App Development

We also provide custom Battery Management Monitor mobile applications providing end-users the ability to monitor, control and manage their batteries remotely in real-time.

Solutions provided include live battery status, charging control, fault alerts, telemetry analytics, device configuration, over-the-air (OTA) updates and cloud sync, specifically for electric vehicles (EV's), energy storage systems (ESS) and industrial battery platforms.

We have experience developing mobile applications using native Android and iOS technologies as well as using cross-platform frameworks such as .NET MAUI, React Native, Flutter and Ionic Framework to develop scalable, secure and user-friendly battery monitoring solutions across devices and operating systems.

Cloud-Connected and Intelligent BMS

Intelligent BMS solutions powered by IoT technology come equipped with connectivity options including Wi-Fi, 4G/LTE, NB-IoT, and Ethernet, in addition to cloud services (AWS IoT Core / Azure IoT Hub). Enterprise-grade security features are also included with the intelligent BMS, such as encrypted data transmission using TLS; secured communication via CANFD authentication and encrypted HSM keys; rollback protection for firmware updates; etc. All these features contribute to the overall reliability and security of your battery systems.

Compliance with Functional Safety (ISO 26262, IEC 61508)

Battery Management Systems (BMS) are platforms that are critical to the overall safety of an electric vehicle (EV) or industrial application therefore, BMS solutions must be designed for high reliability, fault tolerance, and compliance.

Our engineering team develops BMS solutions that meet the functional safety standards of ISO 26262 for electric vehicle applications and IEC 61508 for industrial applications and energy storage systems.

We incorporate ASIL-D and SIL 2/SIL 3 safety architectures in our BMS solutions through the use of advanced safety diagnostics, redundant monitoring, Hazard Analysis and Risk Assessment (HARA)/Failure Mode and Effects Analysis (FMEA), thermal protection, traceability, and certification support for UL, SGS-TÜV, and CSA requirements.
