The EN 55025 international standard is a European standard for the immunity of electronic equipment from electromagnetic interference. The EN 55025 certification ensures that electronic products will not cause interference to other electronic products and that they will not be susceptible to interference from other electronic products.
The EN 55025 certification is required for all electronic products that have lithium batteries that are sold in the European Union. This is to ensure that the lithium batteries will not cause a fire or explosion if they are exposed to an electromagnetic pulse.
EN55025 certified products are also required to have a minimum level of safety in order to protect the user from electric shock.
The EN55025 frequency range for e-vehicles using lithium battery
EN55025 certification is required for all e-vehicles and LEVs sold in the European Union. The certification guarantees that e-vehicles and LEVs are safe and compliant with the EN55025 standard.
The radio disturbances caused by the operation of e-vehicles and LEVs must be limited in order to protect on board receivers, such as GPS or Bluetooth. The EN55025 standard sets the limits and procedures for the measurement of radio emissions in the frequency range of 150 kHz to 5 925 MHz.
This includes both the complete vehicle and the vehicle body construction. The EN55025 standard is primarily intended for the automotive industry, but it can also be applied to other types of vehicles, such as boats, internal combustion engines, trucks, or other transportation machines.
The EN55025 standard covers the following topics:
– General requirements
– Measurement methods
– Limiting values
– Test setup
– Test report
The EN55025 standard is available from the European Committee for Electrotechnical Standardization and defines the radio frequency range, emission levels, test methods, the frequency band range, and test methods for e-vehicles and e-boats.
The on board receivers that EN55025 protects include, but are not limited to, the following:
– Broadcast receivers (sound and television)
– WiFi
– V2X
– Bluetooth among others with radio disturbance characteristics
EN55025 does not apply to Radio Frequency radiation or voltage pulses, which are protected by ISO standards. These topics are addressed in ISO publications. The EN55025 standard is subject to change depending on the wishes of the client (e.g., vehicle manufacturer) and the supplier (e.g., component manufacturer).
Products that require EN 55025 certification
Below is a list of products that require the certification:
-Lithium batteries
This is to ensure that the lithium batteries will not cause a fire or explosion if they are exposed to an electromagnetic pulse.
-Electronic products with lithium batteries
Products are also required to have a minimum level of safety in order to protect the user from electric shock. This minimum level of safety is known as the “essential safety requirements”. It is important to note that.
-Electronic products with radio disturbance characteristics
EN55025 certified products are less likely to catch fire or explode if they are exposed to an electromagnetic pulse.
Products that are required to be EN 55025 certified include:
– Computers
– Telephones
– Televisions
– Radio receivers
– Amplifiers
– Portable electronic devices
-Vehicles
-Boats
-Internal combustion engines
Product testing for EN 55025 certification
The following tests are required for the certification:
– EMC immunity testing
The EMC immunity test is conducted to assess the product’s immunity to electromagnetic interference. The product is exposed to different levels of electromagnetic interference, and the product’s performance is monitored during the interference. It is important for the product to continue functioning properly during the exposure, in order to pass the EMC immunity test.
– EMC emissions testing
The EMC emissions test is conducted to assess the product’s electromagnetic emissions. The product is placed in an anechoic chamber, and the electromagnetic emissions from the product are measured. The product must meet the emission limits specified in EN 55025 in order to pass the EMC emissions test.
– Electrical safety testing
The electrical safety test is conducted to assess the product’s safety in the event of an electric shock. The product is placed in a test rig, and an electric current is passed through the product. The product’s safety is assessed during the electric shock.
EN 55025 certificate process
This process usually takes 4 weeks. The certificate is valid for five years. After five years, the product must be retested and recertified in order to maintain EN 55025 certification.
