In terms of the EMC, electric devices should fulfil two conditions – they have to be resistant to disturbance and cannot disturb operation of other devices by emitting disturbance. The emission and resistance levels are precisely specified and standardized. The tests investigate the resistance and emissions of the prototypes created in the CLE. The goal is to ensure they meet all the applicable standards.

CLE is the only laboratory in Poland which has the equipment for testing the EMC of devices with several hundred kilowatts of power as well as supply and load current up to 800 A.

The measuring equipment of the Electromobility Laboratory Centre makes it possible to measure the intensity of the electric and magnetic fields emitted by devices.

This means we can precisely define the effects which charging stations have on their surroundings. The resulting knowledge helps us minimize the effects which could negatively affect the operation of the charging infrastructure or other devices operating nearby.

Electric energy purchased by the end customer, supplied to the point of consumption, should be of appropriate quality. The devices supplied cannot have any negative effects on the power grid and reduce the quality of the electric energy.

Tests conducted at the CLE laboratory address all the key electric parameters of the prototypes we make. The goal is to create solutions which in no way disrupt the parameters of the energy supplied.

The world is switching to electromobility and investments in high power devices are increasing.

Electric current flow is directly connected with thermal energy release. The higher the power, the more heat is generated. The research conducted by the CLE in this area focus mostly on developing the most effective method of carrying this heat away from devices. This is important from the perspective of safety, but also reliability and lifespan of the devices. For some electronic components, a 10% change of the operating temperature reduces their lifespan by half.

Thanks to series of artificial loads with energy reversed to an AC grid, it is possible to perform long-term load tests with a reduced consumption of power from the grid. This is particularly important for testing high-power devices, both in terms of energy efficiency and environmental protection.

This is one of the most important areas of testing and research. A broad array of analyses performed in this respect makes it possible to determine if and to what extent is the given device safe for the users and protects them against an electrical shock.

Currently, the range of the tests is even expanded to contact current testing.

Noise is becoming a growing problem for our environment, particularly in large conurbations. Scientific research demonstrates that after stress, noise is the second source of illness in humans. The expert team of Ekoenergetyka scientists performs tests and implements research projects intended to develop passive and active solutions for minimizing the noise emitted into environment.

The works focus mostly on the electric vehicle charging infrastructure. The centre is equipped with state-of-the-art measuring equipment which meets global standards, such as acoustic camera with a hexagonal matrix of 128 microphones, precise acoustic imaging system or sound analyser.

Tests in climatic chambers make it possible to simulate the conditions in which electrical devices may work, from frosty winters to scorching summers. This shows us how the given device will work and react to various values and fluctuations of the temperature and air humidity.

he climatic chambers used by the CLE enable normative testing of prototype operation in ambient temperature of -70°C to + 150°C in a walk-in chamber, as well as -70°C to +180°C in a 750l chamber. In both chambers, it is possible to simulate relative humidity of 10 to 98% Rh.

In the Ekoenergetyka laboratories, ageing and corrosion chambers are used for normative material testing in the scope of accelerated ageing concerning the effects of UV radiation or radiation similar to solar spectrum.

The accelerated corrosion tests are carried out on salt mist atmosphere or with spraying.

The measuring devices used in the Electromobility Laboratory Centre enable complete testing of the IP protection rating, The enclosures of devices installed outdoors have to effectively protect their internal electric components. This protection concerns the ingress of dust, various particles and water (e.g. during rain).

The tests assess protection against access to hazardous parts, ingress of solid foreign bodies, as well as ingress and effects of water.

In the Electromobility Laboratory Centre, a qualified team tests the IK resistance rating, which is an impact resistance grade of devices. 

The laboratory is equipped to classify the enclosure impact resistance within the range of IK0 to IK10 using the pendulum impact hammer or the drop hammer method.
