AC and DC EVSE charging-station control, metering, communication and power boards
EV Charger, BMS & Energy PCB Manufacturer
PCBArise manufactures PCB and PCBA for EVSE charging stations, on-board chargers, BMS, DC-DC converters, traction inverters, energy-storage systems and renewable-energy controls. The same quote may include high-current power, cell sensing, isolation, communication and outdoor service requirements, so the route is split by vehicle-mounted, charging-infrastructure or grid-side product scope before production is planned.

EVSE, BMS, OBC & Energy-Storage PCB Applications
EV and energy buyers search for a supplier around a specific power product. We cover the vehicle, charger and grid-side electronics that sit between the battery, the power conversion stage and the communication network.
On-board charger (OBC), DC-DC converter and traction-inverter electronics
BMS cell-monitoring, master/slave, balancing and battery-pack interface boards
EV charge-point communication, payment, display and protection modules
Solar inverter, microinverter, wind converter and grid-tie interface boards
Energy-storage system (ESS) and power-conversion system (PCS) electronics
Smart-meter, energy-monitoring and renewable-energy gateway boards

What EV and Energy PCB Buyers Need to Qualify
An EV charger or BMS PCB is both a power product and a measurement product. Buyers need a build partner who can separate vehicle-mounted quality requirements from infrastructure scope while keeping isolation, sensing, thermal and outdoor-service decisions visible.
High-voltage isolation: creepage, clearance, slots, coating and cleanliness follow the charger or pack architecture
Continuous current: copper weight, thermal path, connector rating and component placement are sized for sustained load
BMS measurement: cell sensing and current measurement must remain separated from hard-switching noise
Outdoor EVSE service: humidity, temperature swing, corrosion, enclosure and maintenance assumptions affect the board
Power cycling: solder joints, plated-through holes and high-mass components are reviewed against charge/discharge duty
Scope boundary: vehicle-mounted OBC/BMS, charging infrastructure and grid-side ESS each need their own evidence plan
EV Charger and BMS PCB Construction
The power path, sensing density and enclosure determine the stackup and copper. Standard rigid and multilayer PCB production covers the released EVSE, BMS and energy-control design; heavy copper, metal core and advanced builds are reviewed when the application requires them.
EV and energy boards have to balance power, heat, safety and service life.
Charging, BMS, inverter and renewable-energy boards are reviewed as complete power systems, from current paths and insulation to test access and assembly evidence.

Questions to resolve before release.
These answers outline the information engineering needs to confirm the right manufacturing path.
Do you build both vehicle-mounted and infrastructure charging electronics?
On-board chargers, DC-DC converters and BMS boards are reviewed against the applicable customer program and assigned facility. Charge posts, ESS and inverter hardware are scoped to the assigned facility, requested quality evidence and released quality plan; the RFQ confirms the documentation and process controls for the product category.
What copper weight can you build for charging and inverter power stages?
The published reference covers 0.5–12 oz copper across 1–40 layers. Copper weight follows your continuous current and allowable temperature rise. Because heavy copper etches with a trapezoidal profile, achievable trace geometry widens with copper weight — our engineers confirm the build-specific geometry during project DFM review.
Can you assemble BMS boards with high channel counts and fine-pitch front ends?
The published PCBA envelope includes 01005 (0.4 × 0.2 mm), 0.25 mm minimum BGA pitch, QFP/QFN down to 0.15 mm spacing, ±0.025 mm (±25 μm) X/Y placement accuracy and ±0.2° in θ. SPI, AOI and ICT coverage are selected against the assigned line, package mix and released quality plan; final limits are confirmed at RFQ.
How do you manage heat in charging modules and inverters?
Where conduction to the chassis is the dominant path, we move to metal core — aluminum PCB reaches up to 3.0 W/m·K thermal conductivity, and ceramic substrate is available for higher power density. On FR-4 builds, High-Tg TG170 plus thermal via design is the usual approach. Send the thermal requirement with your RFQ and engineering will recommend the construction.
Do you provide conformal coating for outdoor charging equipment?
Yes. Conformal coating is a standard value-added service, along with IC programming, cable and harness assembly, box build, and final packaging. For high-impedance sensing nodes on BMS boards we treat cleaning and coating as a functional process step, not a cosmetic one.
What traceability and testing do you provide for energy products?
MES traceability can link component, lot, process and panel records at the level agreed in the released quality plan. Testing may include 2D/3D AXI, ICT, FCT, burn-in and boundary scan/JTAG where the package, access and project acceptance plan support them; coverage and limits are confirmed before release.
