OEM / ODM Battery Management System (BMS) Solutions for Your Application

Key Takeaways

• Our BMS solutions can be customized for any lithium chemistry including Li-ion, LiFePO4, and LTO.
• We support a wide range of communication protocols such as CAN, RS485, and SMBus for seamless system integration.
• Custom firmware development ensures the BMS matches your specific balancing, protection, and data logging needs.
• Rigorous testing per IEC 62619 and ISO 26262 functional safety standards is standard on all custom BMS units.
• We protect your IP with NDAs and never reuse client-specific designs.

The lab bench holds a battery pack prototype, wires snaking to a test jig. An engineer adjusts parameters on a laptop, monitoring cell voltages as the BMS balances the pack under load. This is where custom battery management systems are born—not from off-the-shelf modules, but from a collaborative OEM/ODM process that aligns the BMS to the exact demands of your application.

OEM vs ODM BMS Scope: Engineered to Your Spec

We deliver OEM and ODM battery management system (BMS) solutions that match your electrical, mechanical, and communication requirements. If you come with a complete specification—voltage limits, balancing topology, connector pinout, enclosure drawings—we build your BMS under your brand (OEM). If you define performance targets and we propose the architecture, select the microcontroller, and write the firmware, that is ODM. Either path, our engineering team handles the full lifecycle from concept to mass production.

Customizable BMS Attributes

Every BMS can be adapted along these dimensions:

• Cell configuration: Series cell count from 1S to 32S and beyond; parallel strings for capacity scaling. Configurable per Li-ion, LiFePO4, LTO, NMC, and other lithium chemistries.
• Voltage & current ratings: Continuous discharge and charge current ratings tailored to your load profile; peak and inrush handling.
• Balancing method: Passive balancing or active balancing (up to 2 A per cell); configurable balance start voltage, deviation threshold, and timing.
• Communication interfaces: CAN 2.0B, RS485, SMBus, I2C, UART as standard; wireless options (Bluetooth, Wi‑Fi) for remote monitoring.
• Protection parameter sets: Over/under-voltage, overcurrent, short circuit, over-temperature, and cell imbalance limits—all programmed to your safe operating area.
• Firmware customization: Bootloader, state machine logic, event logging, SoC/SoH algorithms, and communication protocol stacks written to your spec.
• Form factor & connectors: Board outline, mounting hole pattern, connector types (JST, Molex, Amphenol, or custom), and mating harnesses.
• Housing & packaging: Injection‑molded, sheet‑metal, or extruded enclosures; IP ratings from IP20 to IP68; potting and conformal coating for harsh environments.
• Branding & labeling: Silk‑screen, label, and firmware splash screen with your logo, model number, and regulatory marks.

Customization Workflow: From Brief to Delivery

1. Requirements capture: You provide the cell datasheet, target pack voltage/capacity, environmental conditions, and any relevant standards. We map out the functional specification.
2. Engineering design & simulation: Our hardware team selects components and simulates thermal, EMC, and fault conditions. Firmware is prototyped concurrently.
3. Rapid sampling: Functional prototypes are built and bench‑tested. We ship sample units with a test report for your evaluation.
4. Approval & design freeze: After you validate the sample (and any iteration rounds), we freeze the BOM, firmware, and manufacturing test procedures.
5. Production & delivery: Pre‑production pilot run, full‑scale manufacturing, 100% end‑of‑line testing, and shipment to your assembly line or warehouse.

Branding and Private‑Label Options

Your BMS can carry your identity completely. We do not co‑brand or reference ourselves on the unit unless you request it. Options include:

• Custom top‑screen artwork (company logo, product name, serial number location).
• Branded packaging with your part number and barcode.
• Firmware startup screen with your logo and revision info.
• User manuals, datasheets, and compliance documents in your corporate template.

Tooling, Sampling, MOQ, and Lead‑Time Expectations

For projects requiring a custom enclosure or connector overmold, tooling investment and lead time scale with geometry complexity. Simple board‑only BMS designs may use standard PCB fabrication; complex housings may need rapid‑tooled soft molds for pilot runs. MOQs depend on component procurement and assembly line setup, with lower volumes typically accepted for ODM engagements. Sample lead times range from weeks for straightforward adaptations to longer for full–custom designs. We will provide a transparent project timeline after evaluating your requirements.

IP Confidentiality and Quality Assurance During Custom Runs

We treat every custom development as proprietary. A mutual NDA is standard before technical exchanges. Design files, firmware source code, and test protocols remain your exclusive property. In production, every BMS undergoes automated optical inspection (AOI), in‑circuit testing, and a full functional test cycling the unit through all protection states. We follow design‑for‑compliance practices for IEC 62619, UL 1973, and ISO 26262 where required, and can support formal certification at partner labs.
