Custom EV PDU engineering
custom EV PDU · Product category / custom-engineering capability
TRHT works with vehicle OEM and system teams to define custom high-voltage distribution around the vehicle architecture, load map, packaging envelope, and control requirements. Final ratings, interfaces, and validation scope are confirmed from project data.
An EV PDU can coordinate high-voltage paths from the battery to traction, charging, conversion, thermal, and auxiliary loads. The component mix is selected around the vehicle electrical architecture.
Voltage window, continuous and peak duty, load branches, fault strategy, connector layout, enclosure space, cooling, and control ownership change from one platform to another.
Project-dependent integration may include contactors, pre-charge, fuses, current or voltage sensing, HVIL, and CAN/LIN or discrete control interfaces where required.
Busbar routing, connector selection, branch outputs, mounting, sealing targets, and service access are mapped to the vehicle envelope rather than assumed from a generic model.
Share the nominal and operating voltage window, continuous and peak current with duration, branch loads, protection ownership, and pre-charge requirements.
An SLD, BMS/VCU interface expectations, CAN/LIN needs, connector preferences, cooling, environment, mounting space, and project stage help engineering define a reviewable starting point.
The normal path is requirement capture, architecture review, mechanical/electrical definition, prototype planning, and alignment on acceptance criteria.
DVP&R and end-of-line checks are planned against the approved configuration. Existing testing visuals show process context, not completed validation for every product.
Submit the available SLD or load map, voltage and current duty, branch and protection requirements, control interfaces, packaging constraints, project stage, sample context, and target production context. Engineering can then identify the information still needed before a technical proposal.
Evidence context
These visuals support a conservative engineering and workmanship context. They do not identify an exact model or prove a universal rating, certification, customer case, or completed validation result.
Buyer questions
Provide the voltage window, continuous and peak current, load list, SLD, protection and pre-charge requirements, control interfaces, connectors, installation envelope, environment, project stage, and quantity context.
Depending on the architecture, the design may integrate contactors, pre-charge, fuses, sensing, HVIL, busbars, connectors, branch outputs, and CAN/LIN or discrete interfaces.
An EV PDU generally distributes and protects high-voltage power to vehicle loads, while a BDU/BJB is typically centered on battery isolation, main connection, pre-charge, and pack service functions. The boundary is defined by the vehicle architecture.
Communication and discrete control requirements can be reviewed as part of the project interface definition; the final mapping depends on the BMS/VCU architecture.
The voltage window, continuous and peak duty, fault data, load capacitance, switching sequence, thermal conditions, service strategy, and applicable acceptance criteria determine the selection.
An SLD, load list, interface definition, preliminary mechanical envelope, control logic, environment, protection expectations, project stage, and sample or production context are useful starting inputs.
