From 3.3kW single-phase chargers for passenger EVs to 20kW liquid-cooled units for commercial vehicles — click any model to view full specs on our website.
Air-cooled Air-cooled Air-cooled Liquid-cooledWe are not a trading company — we design, prototype, test, and mass-produce every power module in-house.
Full digital power design team handles PFC, DCDC, and inverter topology, control firmware, and CAN protocol integration for your vehicle platform.
PCB layout, components, and mechanical design follow automotive standards. Vibration, thermal cycling, and salt-spray testing before every delivery.
Bottom cooling or forced air cooling options enable fully sealed units for under-hood, chassis, and battery-box mounting in any climate.
Standard CAN communication with Bootloader-based firmware updates and in-field parameter tuning — one hardware, many vehicle variants.
From 48V low-speed vehicle packs to 900V high-voltage platforms, with 110V/220VAC output options for global grids.
Custom housing, connector, firmware, and branding available. Low MOQ for prototype batches, scalable to series production.
A clean, predictable NDA → sample → validation → production flow that keeps your project on schedule.
Share your battery voltage, AC input, output power, and CAN protocol. We confirm model selection or propose a custom design within 2 working days.

Q: What is an on-board charger (OBC)?
A: An on-board charger is installed inside the vehicle and converts AC power from the grid or charging station into DC power to charge the vehicle‘s battery pack. It communicates with the BMS to control charging voltage and current for optimal safety and battery longevity.
Q: Can you customize the OBC for my specific battery voltage and communication protocol?
A: Yes. CTS specializes in OEM/ODM on-board charger manufacturing. We customize output voltage, charging power, CAN protocol, connector type, cooling method, and mechanical form factor to match your exact requirements.
Q: What certifications do your on-board chargers have?
A: Our products are designed to meet CE, FCC, RoHS, and EMC standards. Please confirm specific certification requirements with our team for your target market.
Q: What is your minimum order quantity (MOQ)?
A: MOQ varies by product model and customization level. For standard models, MOQ can be as low as 2 units. Please contact us with your project details for an accurate quote.
Q: How do I request a sample or quotation?
A: Email us at info@ctscharger.com with your application details (vehicle type, battery voltage, required power, communication needs). Our engineering team will respond within 1 working day.
