Modular EV Power Solutions
Modular EV power solutions use standardized power modules to build onboard charging and power-conversion systems around different vehicle and system requirements. By adjusting module configuration and power capacity, modular architectures provide a scalable approach for vehicle manufacturers and system integrators that need flexible power-system design and serviceable onboard power solutions.
Modular Onboard Power for Scalable EV System Design
Vehicle and equipment platforms can differ significantly in charging power, low-voltage power demand, electrical architecture, and system requirements. A modular approach provides a practical way to build onboard power systems around standardized OBC and DC/DC power modules rather than relying on a single fixed power configuration.
By using standardized power modules as defined functional building blocks, onboard charging and power-conversion systems can be configured around different project requirements. This provides vehicle manufacturers and system integrators with a clearer basis for building modular power architectures around target power levels, electrical interfaces, and system requirements.

Key Advantages
Scalable Power Configuration
Modular power architecture allows required charging or conversion power to be built around standardized power modules. By adjusting the number or combination of modules, vehicle programs can match different OBC or DC/DC power requirements without redesigning the complete power stage for every configuration.
This provides a scalable way to configure onboard power systems for different vehicle applications and power levels.
Fault-Tolerant Operation
In a supported multi-module architecture, a fault in one power module does not necessarily require the complete power system to stop operating. The affected module can be identified and isolated, allowing the remaining modules to continue operating at reduced power.
This helps maintain partial charging or low-voltage power availability in vehicle applications where continued operation is important.
Module-Level Diagnostics & Serviceability
Modular systems allow faults to be identified at the individual module level through diagnostic tools and communication data. The affected module can then be isolated and serviced without treating the complete power assembly as a single service unit.
This supports more targeted maintenance and can simplify fault handling and spare-parts management, particularly for commercial and fleet applications.

EV Application Solutions
Passenger EVs
Passenger EV programs may require different charging or low-voltage power levels across vehicle variants and project configurations. Modular onboard power products allow the required OBC or DC/DC capability to be configured around standardized power modules according to the target vehicle requirements.
This provides a practical option for passenger EV projects where different power configurations need to be accommodated within the vehicle electrical architecture.
Commercial EVs
Commercial EVs can vary significantly in charging power, auxiliary-load demand, duty cycle, and vehicle configuration. Modular OBC and DC/DC solutions allow system power to be adjusted according to project requirements, while supported multi-module architectures can also retain partial power capability when one module is isolated.
This makes modular power solutions particularly relevant for commercial vehicle projects that require scalable power capability and operational availability.
System Integrators
System integrators and specialized electrified platforms often need defined power-conversion modules that can be incorporated into a larger vehicle or equipment-level electrical system. Modular OBC and DC/DC products provide clear functional boundaries and configurable power options that can be integrated according to project-specific system requirements.
This gives integrators greater control over how charging and low-voltage power functions are incorporated within the overall electrical architecture.

Modular Solution Configuration
Landworld supports vehicle manufacturers and system integrators in defining suitable modular configurations according to target OBC or DC/DC power, module quantity, battery-voltage requirements, system architecture, and operating conditions.
This helps translate project-level power requirements into a practical modular onboard power configuration.
Control & Communication Support
Landworld supports CAN and CAN-FD communication, wake-up logic, control commands, module-status feedback, and coordination with vehicle or upper-level system controllers.
For multi-module configurations, communication and control requirements can be aligned with the intended operating strategy and system architecture.
Interface Definition & Integration
Landworld supports coordination of the electrical, cooling, communication, and connection interfaces required to incorporate modular OBC and DC/DC products into the customer’s vehicle or system architecture.
Interface requirements are aligned according to the selected module configuration and target system environment.
System Validation Support
After the modular configuration is integrated into the target system, Landworld supports verification of power output, communication, control logic, operating modes, protection functions, and system response under defined project conditions.
This helps confirm that the selected modular solution performs as intended within the complete vehicle or system environment.
