As electronic control and electric vehicles continue their rapid evolution, compliance with AIS004 and CISPR requirements is not simply about fulfilling regulations; it is crucial for product success. NexorTest Technologies provides a comprehensive suite of testing services to manufacturers of automotive components such as battery management systems (BMS), LLP motors, RGB modules, EV clusters, and Display Units.
All of these components are required for a vehicle to perform effectively and provide safe operation and a good user experience. We use an end-to-end testing approach to help manufacturers achieve market entry with global compliance.
AIS004 (Automotive Industry Standard) provides guidelines for electromagnetic compatibility (EMC) testing of automotive products in India, while there are global EMC standards for electromagnetic interference (EMI) and emissions through the CISPR (International Special Committee on Radio Interference) standards.
Products that fail to meet electromagnetic compatibility (EMC) standards and emissions level testing can:
In 2024, 174 campaigns affecting 13.8 million vehicles were linked to software and electronic system failures. As vehicles become more like electronic appliances than machines, software errors and failing electronics dominate.
The art of compliance with AIS004 and CISPR standards is, in fact, a strategic act deployed in the product market for success. Certification and EMC testing preserve your brand reputation and help with quick time-to-market access to auto domestic and international auto markets. Otherwise, even great advanced components in the EV world would be denied entry into OEM supply chains and regulatory approvals.
Here are some points:
Electromagnetic Interference (EMI) may interfere with ABS, airbags, or power steering systems inherent to safety, from malfunctioning or outright accidents.
Noncompliant products face rejection by the authorities, delayed certification, or an injunction enforced to recall the long delay before a product finds itself on market—it and more legal liabilities.
Building consumer trust requires compliance. Having witnessed over 13 million recalls since 2024 due to electronics failures, one cannot imagine how EMC-related issues erode brand trust even further.
Proper early identification of the EMC-related problem during development makes costs go low since there is no need for redesign, recall, or brand damage.
AIS004 in India and CISPR around the globe are compulsory standards. Without compliance, the products are not fit to be sold in the main markets, and this limits both OEM partnerships and export potential.
The next section will provide a detailed outline of how NexorTest Technologies certifies all critical automotive components.
The battery management system is essential for an electric vehicle. It's the system that records, manages, and basically protects the battery for the charge/discharge cycle. If this system is compromised, it can result in battery overheating or even combustion.
Tests Performed at NexorTest:
The Low Loss Power (LLP) motors that are used in EVs need rigorous EMC validation due to the factors of high-frequency switching and continuous torque application.
NexorTest Services Include:
Note: LLP motors can introduce harmonics that can have negative effects on important functional components such as ABS and display systems if not measured properly.
The use of RGB lighting modules will enhance the user interface experience within the EV dashboard and interiors, while still providing necessary vigilance against RF noise that can disrupt infotainment or communications.
NexorTest RGB Module Testing:
The EV cluster brings together speed, battery, diagnostics and infotainment data. Testing involving these data streams validates performance in different electromagnetic environments.
Services offered include:
Insight: NexorTest's EV Cluster Test Rig simulates real-time vehicle dynamics for dependable and predictive diagnostics testing.
Automotive display units need to provide visual clarity without apparent or emitted EMI.
Testing Conditions at NexorTest:
At NexorTest, all automotive parts follow a standardized 6-stage programme:
Discuss with clients; understand their plans, product type and required regulations (AIS004, CISPR, ISO, IEC).
Testing is done at an early stage to evaluate the likelihood of compliance failure.
Test rigs designed and built for LLP motors, BMS or Display Units.
All required testing is undertaken using certified instruments and calibrated chambers.
Non-conformities are identified, and recommendations are made with design fix options.
Delivery of certificates under AIS004 and CISPR, and test results accepted by Indian and international authorities.
Here are some points for NexorTest Stands Out:
EMC non-compliance can have serious consequences for automotive manufacturers — from system malfunctions to costly product recalls.
Here are some of the critical risks:
Whether you are making a Battery Management System, Electric Motors, Module, EV cluster or any automotive components, NexorTest Technologies guarantees your components will always be AIS004 and CISPR compliant.
By investing early in certified testing, automotive brands will avoid expensive recalls and delays, while establishing consumer confidence and product assurance.
Certified testing, conducted early, helps the automakers avoid costly recalls and delays, besides building the customer's trust. Something more critical is that AIS004, CISPR certification provides for faster market access and greater acceptance by OEMs and international regulators — making it a pivotal factor for the permanent success of the product.
