Inside the Making of On-Board Chargers: A Step-by-Step Journey from Design to Testing

As electric vehicles (EVs) continue to rise in popularity, the demand for reliable and high-efficiency on-board chargers has skyrocketed. These chargers are essential components that power the heart of an EV, ensuring safe, efficient, and rapid battery charging. At AcePower, a trusted on-board charger manufacturer, every aspect of creating a high-performance charger—from power PCB layout to rigorous aging tests—is handled with precision and care. Let’s dive into the detailed process of how these chargers are designed, tested, and brought to mass production.

From Concept to Circuit: The Power PCB Layout

The creation of an on-board charger begins with the development of the Power PCB (Printed Circuit Board) layout. This intricate design process is crucial for ensuring the charger’s efficiency and safety. At AcePower, the team focuses on minimizing electrical losses by optimizing the design for high power density, which ultimately leads to a smaller form factor while maintaining high performance.

The on-board charger’s power PCB must support the wide voltage range required for various types of batteries, ensuring the charger is flexible enough to handle multiple charging needs. With features like low cost and high power density, the design phase is all about integrating the best elements to ensure the final product meets the industry’s exacting standards.

Building Efficiency: The Integration of DCDC Modules

Once the PCB layout is complete, the next step is the integration of DCDC (Direct Current to Direct Current) modules. These modules are crucial for ensuring bidirectional energy flow, supporting various charging and discharging scenarios. AcePower's on-board charger features a DCDC module that achieves up to 95% efficiency at 300W—delivering exceptional power conversion performance.

By incorporating multiple functionalities into the DCDC module—such as buck, boost, and active discharge modes—AcePower is able to create a compact and highly efficient solution. The module also supports peak currents of up to 270A, making it suitable for fast-charging applications. With an efficient on-board charger, vehicle owners can benefit from quicker, safer charging times, making the entire EV experience more convenient and efficient.

Testing for Durability: Full-Load Aging Tests

The final stage in creating a durable and high-performance on-board charger involves rigorous testing. At AcePower, extensive full-load aging tests are performed to simulate long-term usage under extreme conditions. These tests are designed to push the on-board charger to its limits, ensuring it performs consistently and reliably over time.

During the full-load aging tests, factors like temperature fluctuations, voltage stress, and high current are all carefully monitored. AcePower’s engineers assess how well the charger handles continuous use, identifying potential areas for improvement before the product is released for mass production. It’s through these tests that AcePower ensures the long-lasting performance of each charger, making sure it’s ready for real-world application.
