Custom Battery Management System BMS PCBA Design Manufacturing Turnkey ODM Service
Custom Battery Management System (BMS) PCBA
Battery management boards engineered around your pack, ESS or portable product, with turnkey ODM development that speeds up your launch and lowers your total cost. We design, build and optimize — from schematic to a boxed, ready-to-ship product.
One-Stop Engineering & Manufacturing Capabilities
| Schematic Design | BMS circuit capture, AFE, balancing and MCU selection matched to your cell count and current profile. |
| PCB Layout | High-current, thermal- and EMC-conscious layout with proper creepage and Kelvin sensing for accurate measurement. |
| Component Sourcing | BOM scrubbing, authorized-channel sourcing and AFE/MOSFET availability planning. |
| DFM / DFA Review | Manufacturability and assembly feedback before tooling to prevent costly re-spins. |
| SMT and DIP Assembly | High-speed SMT plus through-hole DIP for power components, wave/selective soldering and AOI. |
| Firmware Development | SOC/SOH algorithms, cell balancing, protection logic, CAN/SMBus/UART communication and OTA. |
| Functional Testing | ICT, FCT, charge/discharge and protection-trip test fixtures with custom test-jig programming. |
| Box-Build Assembly | Enclosure integration, harness and connector mating, sealing and finished-goods packing. |
| Prototype and Mass Production | Rapid NPI samples, pilot build and scalable volume ramp on a single process. |
Customization and R&D Capability
Our engineers custom-develop the BMS board and its firmware for your battery system, so the protection, balancing and gauging logic fit your cells and application.
- ODM design-in — AFE, MOSFET and shunt architecture tailored to your voltage, current and cell count.
- Hardware and firmware co-development — sensing front-end and SOC/SOH algorithms tuned together.
- Protection engineering — over-voltage, over-current, over-temperature, short-circuit and cell-balancing safeguards.
- Feature expansion — add active balancing, CAN/RS485, gauging or wireless monitoring to your platform.
- Confidential development — NDA-protected engineering with clear design ownership for your brand.
Cost Reduction and Efficiency for Your Project
We do more than populate boards — we lower your total cost and shorten your time to market.
| BOM cost optimization | Cross-reference the BOM to equivalent parts that cut unit cost without losing safety or accuracy. |
| Design cost-out | Simplify layer count, consolidate passives and remove redundant parts early in the design. |
| Consolidated sourcing | One supplier, one BOM, fewer purchase orders and less overhead. |
| Faster NPI | Rapid prototyping and DFM feedback compress the design-build-test loop. |
| Supply chain resilience | Qualified second sources reduce stock-out and price-spike risk. |
From Bare Board to Finished Product (Box-Build)
A bare PCBA is only a component. This service carries the board all the way into a finished battery product that ships ready to sell.
- Schematic Design — lock the electrical architecture.
- PCB Layout — deliver a manufacturable, high-current and EMC-conscious board.
- Component Sourcing — secure the BOM through trusted channels.
- DFM / DFA Review — de-risk the build before tooling.
- SMT and DIP Assembly — populate and solder the PCBA.
- Firmware Development — bring the protection and gauging to life.
- Functional Testing — verify every function passes.
- Box-Build Assembly — fit the PCBA into the enclosure, wire harnesses and connectors, then seal and finish the unit into a complete product.
- Prototype and Mass Production — start with samples, then ramp to volume with the same process.
