WHAT WE CAN CUSTOMIZE
Six things we adapt to your vehicle platform
Every OEM and ODM programme starts from the same question: what exactly has to change. These are the six areas our engineering team works through with you before a sample is built.
02 / Communication2
CAN & Communication
CAN messages, BMS and VCU integration, and project-specific communication settings aligned with your vehicle control network.
CAN 2.0 / BMS / VCU
03 / Interface3
Connectors & Interfaces
Connector selection, pin definition and vehicle-side interface adaptation to match the harness you already build.
Connectors / pinout / harness
04 / Mechanical4
Mechanical Integration
Housing, mounting points and packaging evaluated against the space and vibration environment of your vehicle installation.
Housing / mounting / packaging
05 / Integration5
Integrated Power Units
OBC with DC/DC, and OBC with DC/DC and PDU, combined into one enclosure for compact platforms that cannot spare the volume.
2-in-1 / 3-in-1 configurations
06 / Brand6
OEM Branding & Labeling
Logo, nameplate, product label and project-specific identification applied to the unit and its packaging.

PRODUCT PLATFORMS
Start from a platform we already build
Each platform below is in series production and available for project-specific electrical, communication and interface adaptation.
Onboard Chargers
3.3 kW to 11 kW single and three-phase OBCs from 72 V to 800 V, air or liquid cooled, IP67 options.
DC/DC Converters
1 kW to 10 kW converters with fixed or wide-range input, for auxiliary and low-voltage rail supply.
OBC + DC/DC 2-in-1
Charger and converter in one enclosure to cut harness, mounting and certification scope.
OBC + DC/DC + PDU 3-in-1
Charging, conversion and power distribution combined for compact platforms with limited volume.
Bidirectional Chargers
V2G and V2L capable units for vehicles that need to discharge back to an AC load or the grid.
AC/DC Dual-Input Chargers
Two input paths in one unit for vehicles used on both AC infrastructure and a DC source.
OEM / ODM PROCESS
From Requirements to Production
A structured development path helps EV OEMs reduce uncertainty from initial requirements through sample validation and production. Requirement review, technical proposal, sample development, testing and validation, production, then delivery and integration support.
Step 1 Requirement Review
We review your vehicle platform, battery voltage, required power, communication requirements and project needs.
Step 2 Solution Proposal
Our engineering team recommends a suitable product platform and confirms the required customization scope.
Step 3 Sample Development
Samples are prepared according to the confirmed electrical, communication and interface requirements.
Step 4 Testing & Validation
Samples are evaluated through functional testing and project validation, with adjustments made when required.
Step 5 Production
After specifications are confirmed, the project moves into production with standardized quality control and final inspection.
Step 6 Delivery & Technical Support
We support shipment, technical coordination and follow-up during vehicle integration and subsequent production.
TESTING & VALIDATION
What every unit goes through before it ships
Custom units are not released on the strength of one good sample. Each configuration is validated against the agreed specification, then checked again in production and at final inspection.
01 / Function1
Functional Test
Input range, output regulation, charging curve, protection thresholds and communication behaviour verified against the specification.
Spec verification
02 / Thermal2
Thermal Evaluation
Continuous operation at rated load with temperature rise recorded on power devices, magnetics and enclosure surfaces.
Rated load / temperature rise
03 / Endurance3
Aging & Endurance
Extended run cycles used to expose drift, connector heating or firmware behaviour that a short bench test would miss.
Extended run cycles
04 / Shipment4
Final Inspection
Every unit checked and labelled before packing, with production records kept against the confirmed project specification.
100 percent before packing
