2026 Updated Pricing for NG‑eCall｜Separate Cost Analysis for T‑Box AECD and Whole‑Vehicle WVTA Approval

NG‑eCall is next‑generation in‑vehicle emergency calling system built upon IMS‑VoIP under UN‑R144 and (EU) 2024/1180. EU opened certification applications starting Jan 1, 2025 and stopped accepting pure 2G/3G CS‑eCall approvals from Jan 1, 2026. Legacy CS‑eCall certificates will expire completely on Jan 1, 2027. Plenty of vendors confuse component‑level AECD certification for T‑Box units and full WVTA vehicle‑type approval whose costs differ drastically. T‑Box evaluation only includes bench‑testing without real‑car crash tests while whole‑vehicle WVTA adds physical crash trials with much‑higher costs. The following breakdown follows 2026 pricing levels for Chinese‑based labs.

1. Official Test Expenses for NG‑eCall

EN17184 specifies functional requirements such as maximum 3‑second IMS connection latency, MSD V3 data transmission, voice‑link quality and GNSS positioning accuracy. EN17240 defines test methodologies covering post‑crash antenna attenuation, ‑40℃ ~ +85℃ temperature cycles, vibration durability and the strict 66‑minute backup‑power cycle (5‑minute call + 56‑minute standby + another 5‑minute call), alongside multi‑radio co‑existence tests.

·T‑Box AECD component‑level bench‑testing costs 150,000‑250,000 RMB at qualified domestic labs. 4G+3G dual‑mode hardware costs more than standalone 4G modules and products with 5G‑NR and optional multimedia functions hit the upper limit of 250,000 RMB. Basic NG‑eCall functions alone cost around 150,000‑180,000 RMB. EU‑based labs charge equivalent 400,000‑700,000 RMB so most Chinese manufacturers choose local labs with ETSI‑compliant platforms.

·Initial testing takes 4‑8 weeks with each revision adding another 7‑15 days. Single‑item supplementary testing costs 5,000‑20,000 RMB and a full round of re‑testing after failing IMS latency, power‑supply or GNSS tests normally costs 30,000‑80,000 RMB.

·Whole‑vehicle WVTA approval including real‑car crash testing costs 1,200,000‑2,500,000 RMB on top of component‑level test fees.

  2. Technical Service Charges

Service packages include UN‑R144 technical document compilation, EN18031 cybersecurity reports, DoC preparation, NB‑body coordination, PSAP simulator testing and EU‑document translation. Experienced local service providers charge 80,000‑200,000 RMB while European consulting firms charge around 250,000‑600,000 RMB (30,000‑80,000 EUR), mostly selected by foreign‑owned auto companies.

  3. NB Notified‑Body Review Fees

This part often gets bundled incorrectly into component‑testing costs.

·For T‑Box AECD projects: NB audit fees range from 7,000‑15,000 EUR equivalent to 53,000‑115,000 RMB. The widely‑rumored 20,000‑50,000 EUR rate applies to whole‑vehicle WVTA approval only.

·Whole‑vehicle WVTA: NB charges 20,000‑50,000 EUR. Multiple car models built on one platform can share one T‑Box certificate to average down overall review costs.

  4. PSAP Interoperability Test Costs

One common misunderstanding exists: EU member states never charge registration fees for PSAP platforms.General EU‑version NG‑eCall interoperability testing with standard ETSI PSAP simulators at Chinese labs incurs zero extra fees. Local adaptation for France, Italy and Spain requires engineer business trips and operator platform coordination costing an extra 30,000‑80,000 RMB. Most export‑oriented projects only run standard PSAP testing without on‑site trials in Europe.

  5. Hardware Revision Costs (Highly Variable Based on Initial Design)

·Fall‑back mechanism is compulsory for NG‑eCall. 4G‑based T‑Box has to support hand‑off from 4G to 3G while 5G units can switch from 5G‑NR down to 4G‑LTE. Redesigning circuits and replacing single‑mode 4G‑only modules costs 50,000‑150,000 RMB.

·Excessive IMS connection latency over 3 seconds is the most‑common failure item. Optimizing IMS protocol stacks only takes 1‑2 months without hardware‑related expenses.

·If backup‑power systems fail the 66‑minute cycle test, upgrading batteries and power‑management circuits costs around 30,000‑80,000 RMB.

·EN18031 (UN‑R155) cybersecurity compliance requires secure boot, firmware encryption and vulnerability repair plans. Inadequate designs bring additional revision expenses and authorities enforce these requirements more strictly in 2026.Carrying out pre‑testing for IMS latency, battery performance, GNSS accuracy and RF co‑existence before formal submission costs about 50,000‑80,000 RMB and raises one‑pass success rates greatly while saving 100,000‑150,000 RMB on repeated re‑testing.

  6. EU‑REP Authorized Representative Fees

Non‑EU manufacturers must appoint a local EU‑based representative. Annual fees for T‑Box components run from 4,000‑12,000 RMB per year with higher rates for whole‑vehicle projects.

  7. Post‑Certification Maintenance

UN‑R144 certificates remain valid indefinitely if communication modules, antennas and RF circuits stay unchanged. Manufacturers cooperate with NB‑bodies on annual COP production‑consistency audits. Under EN17184:2024 released in 2026, MSD‑V3 format becomes mandatory and products with old MSD‑V2 will fail certification directly. EU officials select finished‑T‑Box units randomly for re‑testing; mismatched RF parameters or firmware versions lead to certificate cancellation and full sales bans within European territories.
