What OBC and Integrated Power Systems Does Echelon Manufacture?
Explore Echelon's OBC and integrated power lineup: 3.3-6.6 kW OBC+DC-DC units, an 11 kW bidirectional V2G charger, three-in-one power units and portable chargers.
Echelon Energy Technology (Hangzhou) Co., Ltd. designs and manufactures on-board chargers (OBCs), DC/DC converters and integrated power systems for commercial and specialty electric vehicles - delivery vans, electric tricycles, golf and low-speed vehicles, ground support equipment and agricultural machines. This overview maps the current product lineup to typical vehicle projects.
On-Board Chargers: 3.3 kW and 6.6 kW Platforms
The core OBC platforms cover 3.3 kW and 6.6 kW charging power on 72 V, 96 V and 320 V battery systems, with liquid or air cooling options and CAN 2.0 communication as standard. They are the base for most light commercial and specialty vehicle projects. For power-level selection on light electric vehicles, see how to choose a 3.3kW vs 6.6kW on-board charger.
OBC + DC-DC Combined Units
Combining the OBC with a DC/DC converter in one housing saves wiring, installation space and a separate component order. Echelon's combined units pair a 3.3 kW OBC with a 1 kW DC/DC converter (72 V, 96 V and 320 V platforms) or a 6.6 kW OBC with a 1.5 kW DC/DC converter (96 V and 320 V) - both with CAN control and OEM/ODM customization.
AC/DC Dual-Input Chargers
For vehicles that charge from two different AC sources, the 6.6 kW dual-input charger supports an 80 V platform with CAN 2.0, AUTOSAR and UDS support - designed for commercial vehicles that need flexible charging options.
Bidirectional OBC (V2G/V2L)
The flagship is an 11 kW bidirectional on-board charger with an integrated 3 kW DC/DC converter on a 360 V platform. Liquid-cooled, it supports V2G and V2L operation - the vehicle can feed power back to the grid or to external loads. New to bidirectional charging?

Three-in-One Integrated Power Units
The three-in-one unit integrates the OBC, DC/DC converter and PDU (power distribution unit) in a single housing - the highest level of integration for vehicle power electronics, reducing wiring, connectors and installation time.
Portable EV Chargers
A 1.9 kW portable charger for 72 V systems works as both a portable and on-board unit - a practical backup or primary charging option for light vehicles and fleets.
Which System Fits Your Vehicle Project?
- Light EVs, golf carts and LSV platforms: 3.3 kW or 6.6 kW OBC + DC-DC combined units.
- Commercial vehicles with dual AC sources: 6.6 kW AC/DC dual-input charger.
- Premium platforms with grid or load export: 11 kW bidirectional OBC (V2G/V2L).
- Space-constrained designs: three-in-one integrated power units.
- Backup and flexible charging: 1.9 kW portable charger.
Customization and Engineering Support
All platforms support OEM and ODM customization: electrical parameters, CAN communication, connectors and configuration. Engineering support runs from requirement review through prototypes, testing and series production - under the IATF 16949 quality system. How Echelon manufactures and tests OBCs explains the process in detail, and who manufactures OBCs for commercial EVs covers the supplier landscape.
