How to Qualify an OBC Supplier for Automotive Production
A production-ready OBC supplier must prove more than electrical performance: verify design ownership, manufacturing controls, traceability, validation, capacity, change discipline and ramp readiness.

On-Board Charger Lead Times: What Actually Moves Them, and How to Plan Around It
Lead time on a charger is set by four things — magnetics, switching devices, potting and the certification slot — and only one of them is about how busy the factory is. A quote that names a number without naming the constraint is a guess.

Who Actually Makes Your On-Board Charger: Reading the Supply Chain Behind the Label
Three suppliers can quote the same part number and only one of them owns the factory. The difference shows up in the R10 certificate, the change-notification process and who answers when a field failure is traced back to a solder joint.

Charging a 48 V Low-Speed EV: The Single-Phase Constraints Nobody Puts on the Datasheet
A 48 V pack makes the battery cheap and the wiring heavy. It also makes the wall socket, not the charger, the real limit — and that changes which power rating is worth paying for.

UNECE R10 and ISO 26262: What a Charger Supplier Must Be Able to Hand You
“Designed to” and “certified to” are not the same sentence, and the difference decides who pays when the vehicle type approval stalls. Here is the document set to ask for before you sign.

Why On-Board Chargers Derate — and How to Specify Around It
A 6.6 kW charger is 6.6 kW at one set of conditions. Ambient temperature, coolant temperature, input voltage and duty cycle each move the number, and the datasheet rarely shows all four on the same curve.

IP66 vs IP67 on an On-Board Charger: What the Second Digit Really Covers
IP67 does not mean “more waterproof” in the way most specification meetings assume. The second digit describes a specific test — immersion for 30 minutes at 1 m — and says nothing about steam, detergent or thermal cycling.

Bidirectional On-Board Chargers and V2L: What Actually Changes in the Vehicle
A bidirectional charger is not a charger with a relay on the output. It adds an inverter stage, anti-islanding logic and a neutral reference — and each of those moves cost and risk into the vehicle, not just into the charger.
