After adding power accessories, check the electromagnetic compatibility and high-voltage safety effects separately, and record the accessories specifications, installation location, power path, and approval boundaries after modification.
Accessory changes are first divided into two review lines: changes in electrical accessories
Changes to electrical accessories require two types of evidence to be saved separately: the official page explaining the rules, and the project form recording the vehicle or transaction under review.
United Nations Economic Commission for Europe explains that UNECE Regulation No. 10 involves electromagnetic compatibility of vehicles, components and independent technical units. Adding electrical accessories will trigger a recheck of the installation status.
United Nations Economic Commission for Europe explains that UNECE Regulation No. 100 is used to define the safety boundaries of electric drive systems and energy storage systems. Changes in attachments cannot be automatically presumed to be within the scope of approval based on the original vehicle model name.
Use attachment name and specifications to lock modification objects
The main file of the accessory should first write the manufacturer, model, rated voltage, current or power, certification mark and installation quantity. The mounting location, power point, ground, wiring harness routing and protection devices are then connected to the same VIN. Only when the identity of the accessory is consistent with the actual installation status, can R10 or other EMC data be clearly applicable.
What is needed for EMC and electrical safety: changes in electrical accessories
Two judgment lines are used for electromagnetic compatibility and high voltage safety. The EMC line checks whether accessories and installation configurations fall within the testing or approved range; the electrical safety line checks power intake, grounding, protection and high-voltage boundaries. Low-voltage accessories must also be proven not to enter or affect the high-voltage system.
Modification affects line review
| Check fields | Technical values that should be recorded | Direct evidence | Action in case of failure |
|---|---|---|---|
| Accessory name and specifications | Manufacturer, model, function, rated voltage, current or power, certification mark and quantity | Nameplate photo, component specifications, purchased parts list | Stop installation if the model or rating cannot correspond to the actual product |
| Installation location | Body area, fixing method, relative position to antenna/controller/high-voltage components and approved drawing number | Installation drawing, photos with orientation and physical vehicle measurement records | Enter technical review when the actual position deviates from the approved drawing or changes the electromagnetic environment |
| Power supply circuit | Power supply point, system voltage, normal/peak current, connector, grounding point and branch circuit | Electrical schematic diagram, power supply diagram, installation record and physical vehicle inspection | Power supply shall not be delivered when the power supply point, load or grounding is unknown |
| Wiring harness and fuse protection | Wire diameter, direction, fixed spacing, insulation and wear/heat source protection, fuse or circuit breaker specifications and location | Wiring harness diagrams, component specifications, installation photos and continuity/insulation inspection records | Removal and rectification if the protection capacity, wire diameter or wiring path does not match |
| R10 or EMC evidence | Report or certificate number, accessory model, test configuration, installation conditions, version and page number | Device EMC report, approval certificate or manufacturer's compliance information | Supplementary testing or written confirmation if the evidence does not cover current accessories or installation conditions |
| Impact on the high-voltage system | Whether it enters the high-voltage boundary, whether it affects the insulation/interlocking/orange wiring harness, isolation distance and inspection results | Vehicle high-voltage layout drawings, installation drawings and electrical safety inspection records | Suspension of modifications when the high-voltage boundary is involved but there is no electrical safety assessment |
| Change approver | Name, role, scope of authorization, approval object, conclusion and date | Change application, project approval and authorization matrix | Upgrade approval when the approval scope is inconsistent with the modification object |
Any differences in the table are linked to the change request and closure records. Engineers cannot use quotation, invoices or generic vehicle model names to demonstrate wiring harness specifications, insurance protection or approved coverage.
No delivery when approval boundaries are unclear: changes to electrical accessories
The accessory model, actual installation location, power circuit, wiring harness protection and EMC data must form the same configuration. If it is just a change in location, it is also necessary to determine whether it changes the antenna distance, grounding, wiring harness direction or electromagnetic environment; if it touches high-voltage components, insulation or interlocking boundaries, it will be transferred to electrical safety assessment. The modified vehicle does not go into customer delivery before approval for coverage or safety impact is not closed.
How on-site conditions get verified
When dealing with the question of "why electromagnetic compatibility data need to be reviewed after adding electrical accessories to electric vehicles" in Africa, technical judgment should fall on the conditions that can be inspected on site. Itemize power source, charging or supply, roadway, load, environment, tools, personnel qualifications and safety boundaries with current status, source and date of inspection. Where measurements or documentation are absent, mark the content "to be confirmed" instead of "has" or "can be used directly."
For the same technical condition, it is necessary to write down "what is met", "who confirms it", "when to review" and "what to do if it is not met". Publicly available technical information can explain methods and parameter meanings, but cannot replace confirmation of on-site capacity, equipment status, vehicle model versions or local service capabilities. Recording unavailability conditions together with alternatives allows procurement, delivery and after-sales to act on the same page.
Use the following record structure to keep the review fields, evidence sources, and release conditions traceable:
| Verification field | Recording requirement |
|---|---|
| Site conditions/technical fields | Record the current value, direct source, and applicable scope |
| Current value and unit | Record the date, method, reading, and supporting evidence |
| Source and date of inspection | Record the document name, version, page, or original URL |
| Responsible people and safety boundaries | Describe the discrepancy and the decisions it affects |
| Substitution or suspension when not satisfied | Assign an owner, deadline event, and reopening condition |
Use this table to keep the evidence and affected decisions traceable. The final decision must still be checked against the original record and the current vehicle or batch.
Checks needed before a commitment
Before making a quote, test drive, delivery or after-sales commitment, check the checklist to see if key conditions are closed. As long as there are unconfirmed items that will affect safety, performance or delivery time, the scope of the commitment will be narrowed to the proven part, and the points for supplementary verification and review will be clearly defined. After passing the review, update the version number and responsible person. The previous conclusion remains in the record for historical reference. Do not allow different versions to be circulated externally at the same time.
After completing the on-site review, backfill the measurement values, units and responsible persons into the Africa condition table "Why should electromagnetic compatibility data be reviewed after adding electrical accessories to electric vehicles", and then update the scope of commitment.
FAQ
What is the minimum content of an attachment change package?
At the same time, submit the accessory specifications, installation location, power circuit, wiring harness and protection plan. Any missing item may affect the EMC or electrical safety judgment.
Only changing the installation location, do I need to review the EMC?
First determine whether the change in location changes the direction of the wiring harness, grounding, antenna, or electromagnetic environment, and then decide whether to confirm the file or retest.
Why do we need to check the high-pressure safety of low-voltage accessories?
If the accessory does not come into contact with the high-voltage system, the evidence of no impact can be recorded; when taking power or installing a high-voltage boundary, an electrical safety review must be carried out.
Does the model parameter list alone confirm local availability?
No. The parameter table can only support the fields of the vehicle model or the equipment itself. On-site capacity, installation conditions, network and personnel capabilities still need to be confirmed separately. This question should be reviewed in conjunction with Africa's "Why should electromagnetic compatibility data be reviewed after adding electrical accessories to electric vehicles" together with the corresponding original records.
A technical condition field is missing — can delivery still be promised?
If the gap may affect safety, performance or time, relevant commitments should be suspended first; only a tentative plan should be given within the unaffected range, and the verification node should be written down. This question should be reviewed in conjunction with Africa's "Why should electromagnetic compatibility data be reviewed after adding electrical accessories to electric vehicles" and the corresponding original records.
