where does one buy a 600VDC 10kW power supply?

Does this mean battery charging ?
I'm not across recent EV power connections as to whether the power supply has all the smarts, or the vehicle has total control of the power flow/protection/charging profile.

we do heat transfer

That means no person in your company has basic training with this kind of power?

There are courses offered now for the car repair business for the correct handling of electric vehicle safety in the repair shop. In Germany, a car repair shop is not allowed to work on electric vehicles, without having done this safety course. They are not even allowed to repair a bumper!

I highly recommend such safety course before starting work on this project!

I did indeed suggest such a course. But do these courses teach you how to work with high voltages or how to set them up as well? It's like the wiring regulations for buildings, they don't teach you how it works just how to install it.

I do not know about this in your country.

In Germany the full course is almost 2 weeks long and you learn everything from the basics to details of handling electric vehicles and its all hands on.
Only when such certificate exist, is the car repair shop allowed to work on electric vehicles.


Simon:
We are not working on electric vehicles, just designing and building equipment for them. So really it's just about higher voltage safety.

A safety assessment would likely indicate that the test vehicle be solidly earthed for the purposes of testing, assuming that has no implications.  It sounds like you then position some accessory equipment in the test vehicle and provide a cable harness to your equipment.  You then need to map out all the hazards and how to mitigate them. 

I guess some initial summary would include if your equipment and all cabling was completely insulated, or had protective earth connections to all key or exposed metalwork, and to some suitable IP rating, and does it include safety protection for plausible fault situations like over-temp sensing etc.  There are usually guidelines in local standards as to the minimum requirements to manage various hazards - the list could go on and on - and you would need to be competent in identification and assessment.

If you want a 'proper' power supply ask photonic induction.
