As electrification accelerates across industrial vehicles such as AGVs, forklifts, cleaning machines, aerial work platforms, and utility vehicles, selecting the right onboard charger becomes a critical design decision.

An onboard charger (OBC) is a power conversion device installed inside an electric vehicle that converts AC input into controlled DC output for battery charging.

Unlike off-board chargers, an onboard charger is permanently integrated inside the vehicle. Therefore, it must meet not only battery requirements but also mechanical, thermal, electrical, and communication constraints of the overall system.

Delta Electronics provides onboard charger solutions ranging from 720W to 1200W, supporting both plug-and-play and communication-based architectures for industrial electric vehicle applications.

When selecting an onboard charger, engineers must evaluate multiple system-level parameters to ensure optimal performance, safety, and long-term reliability.

In practice, onboard charger selection is a multi-dimensional engineering problem involving electrical compatibility, thermal constraints, and system integration.

In this article, we discuss five critical design considerations that should be carefully assessed when integrating onboard chargers for industrial vehicles.
