Product Features
The Landworld 2-in-1 integrated power system combines a 6.6kW bidirectional on-board charger and a 2.5kW high-voltage DC/DC converter in one compact, liquid-cooled enclosure. In forward charging mode, the OBC converts a single-phase 85–265VAC input into controlled high-voltage DC power for charging the traction battery. In reverse inverter mode, the system converts traction-battery power into a 220VAC, 50Hz output rated at 3.3kVA for compatible vehicle-to-load applications. The integrated DC/DC converter supplies a nominal 14V output and 179A current for the vehicle’s 12V battery and auxiliary electrical network. Three configurations are available for different high-voltage battery platforms. The system is designed for electric fleet vehicles, delivery vans, light commercial EVs, passenger fleets and selected electrified off-road equipment requiring integrated charging, low-voltage conversion and external AC power capability. |
Bidirectional Inverter with V2L & V2G The Landworld 6.6kW OBC + 2.5kW DC/DC Integration enables efficient power transfer with V2L and V2G, allowing vehicles to power external devices and return energy to the grid. |
Online Upgrades and Fault Diagnosis Supports remote software upgrades and real-time fault diagnosis, enhancing maintenance and operational efficiency for a wide range of electric vehicles and machinery. |
Single and Three-Phase Charging Compatibility Compatible with both single-phase and three-phase charging stations, offering versatile charging options for electric passenger cars and commercial vehicles. |
Digital Design with Redundant Protection Features digital software and redundant protection to ensure safe, reliable performance for electric vehicles in diverse operational conditions. |
