Arrangement for testing electric car components

1. An arrangement for testing electric components of a car, comprising:

a transportable freight container housing at least a test chamber for testing the electric components;

a climate control system configured to control climate conditions in the test chamber of the freight container;

test equipment configured to test the electric components in the test chamber of the container,

a substantially planar auxiliary platform constructed on but different from a roof of the freight container, forming a part of a support structure, and

a roof interface between an interior of the freight container and the roof of the freight container,

wherein the roof interface provides couplings between the test equipment inside the container and the test equipment provided on the support structure so that sides of the test equipment other than a side of the test equipment adjacent to the support structure are exposed to an outside environment external to the arrangement, or between a first unit of the climate control system comprised in the test chamber and a second unit of the climate control system provided on the support structure so that sides of the second unit of the climate control system other than a side of the second unit of the climate control system adjacent to the support structure are exposed to the outside environment external to the arrangement.

2. The arrangement of claim 1 , wherein the container comprises a fireproof inner wall separating an interior of the freight container into the test chamber and a facility room.

3. The arrangement of claim 2 , wherein all electric connections for testing the electric car components are provided to and from the test chamber through the inner wall.

4. An arrangement for testing electric components of a car, comprising:

a transportable freight container housing at least a test chamber for testing the electric components;

a climate control system configured to control climate conditions in the test chamber of the freight container;

test equipment configured to test the electric components in the test chamber of the container,

a platform constructed on a roof of the freight container, forming a support structure, and

a roof interface between an interior of the freight container and the roof of the freight container,

wherein the roof interface provides couplings between the test equipment inside the container and the test equipment provided on the support structure, or between a first unit of the climate control system comprised in the test chamber and a second unit of the climate control system provided on the support structure,

wherein the container comprises a fireproof inner wall separating an interior of the freight container into the test chamber and a facility room, and

wherein the freight container comprises an electric interface to electric input/output equipment configured to input electric inputs to an electric component under test in the test chamber, wherein the electric interface is provided as a connector or a fireproof passthrough in the inner wall.

5. The arrangement of claim 4 , wherein the electric components comprise high-voltage batteries of electric cars, the arrangement further comprising the electric input/output equipment in the facility room and configured to input charge/discharge cycles to a battery under test.

6. The arrangement of claim 1 , wherein a first unit of the climate control system is comprised in the test chamber and a second unit of the climate control system is provided outside the test chamber, and a coupling is provided between the first unit and the second unit.

7. The arrangement of claim 2 , wherein the second unit of the climate control system is mounted or mountable on the auxiliary platform.

8. The arrangement of claim 2 , further comprising a test control system disposed in the facility room and configured to control the climate control system and the test equipment according to one or more testing protocols.

9. The arrangement of claim 1 , wherein the freight container further comprises an electric interface disposed in an exterior wall of the container, the electric interface suitable for testing an electric car component outside the test chamber.

10. The arrangement of claim 1 , further comprising:

at least one door providing access to the test chamber from exterior of the freight container, wherein the at least one door contacts a door frame of the freight container through an insulator, and

a heater configured to heat a contact surface at the location of the insulator.

11. The arrangement of claim 1 , further comprising a further freight container arranged in parallel with the container, wherein the freight containers are locked to each other, and wherein at least some of side walls of the freight containers that face each other are removed to provide enlarged test chamber extending at least partially over both freight containers.

12. The arrangement of claim 1 , wherein at least one inlet/outlet of a safety system is provided from the test chamber directly to an exterior of the freight container.

13. The arrangement of claim 12 , wherein the at least one inlet/outlet comprises a rupture panel on the roof of the freight container, and wherein the rupture panel is covered by one or more elements of the auxiliary platform.
