Electric vehicles and charging
Pack and drive testing, and the technical file a charge point has to stand behind.
Who buys this: Vehicle and charge-point manufacturers, and their test houses.
Why it matters now
Britain regulates smart charge points in its own right, separately from the vehicle, and the obligations sit with whoever places the unit on the market.
What the work actually involves
Two distinct benches. Pack and module work wants a supply that sources and sinks from the same terminals, so a charge-discharge cycle is one instrument rather than a supply, a load bank and the cooling for it — and at pack voltages that means the 1500 V and above classes. Charge-point work is different: the equipment has to demonstrate behaviour against a supply that can be disturbed on demand, and the evidence has to survive being read by somebody else a year later.
Assessed against
Systems we build for it
- CTS4000 battery test system
Cycling and characterisation for cells, modules and packs.
- Programmable DC with arbitrary transient sequencing
The DC side of military land-platform testing — wide input, and transients you cannot produce with a bench supply.
- Vega high-power bidirectional racks
Integrated racks where the requirement is beyond a single chassis.
Equipment it usually needs
Lines held by another British distributor
Intepro is the North American distributor for these manufacturers, not the British one. We build test systems around their equipment; for the instruments themselves, go to the firm that holds the line here.

Tell us the standard and the device under test. That is enough for an engineer to answer usefully instead of sending a brochure.
