400 kW ultra-fast charging
Alpitronic’s HYC400 gains UL certification
Governments around the world are accelerating policies to increase EV adoption by 2030, driving rapid growth in public charging infrastructure.
Alpitronic
Alpitronic has secured UL certification for its 400 kW HYC400 fast charger. The approval confirms compliance with stringent safety standards and clears the way for deployment in North America and other important markets.
Meeting the growing demand for
higher charging power and shorter charging times while complying with
strict safety requirements is becoming a decisive challenge for the EV charging
industry. Alpitronic has now taken a major step in this direction. With its
HYC400 DC fast-charging system, the Italian company has obtained UL
certification, marking a key milestone for global market access — particularly
in North America.
The HYC400 delivers up to 400 kW of charging power and is
the first fast-charging system developed in Europe to be certified by UL
Solutions under the latest standards for DC electric vehicle supply equipment.
UL Solutions is a globally active testing and certification organisation
headquartered in Northbrook, Illinois, playing a central role in defining
safety benchmarks for electrical and electronic systems. In Germany, the
company operates its national headquarters and an EV charging test centre in Neu-Isenburg
near Frankfurt, where the HYC400 underwent extensive validation.
Performance and safety under demanding conditions
At the Neu-Isenburg test facility, the HYC400 was
comprehensively examined to verify compliance with UL 2202, the safety standard
for DC fast chargers. The testing programme covered electrical performance,
thermal behaviour, high-voltage resilience and operation under challenging
environmental conditions, including humidity. In addition, the personal
protection system was evaluated in accordance with UL 2231, which governs
safety requirements for electric vehicle power circuits.
These standards are increasingly critical as ultra-fast
charging infrastructure becomes more powerful and more widespread. Compared with conventional charging solutions, DC fast
chargers can significantly reduce charging times — a factor that directly
influences user acceptance and the scalability of electric mobility. As
EV sales continue to rise worldwide, reliable high-power charging is shifting
from a differentiator to a basic requirement.
Opening the door to global markets
For Alpitronic, UL certification is not merely a technical
seal of approval. It is a strategic prerequisite for entering markets where UL
standards are mandatory, most notably the United States. Governments around the
world are accelerating policies to increase EV adoption by 2030, driving rapid
growth in public charging infrastructure. At the same time, expectations around
safety, interoperability and operational reliability are rising sharply.
From the manufacturer’s perspective, certification provides
assurance across the entire value chain — from charging network operators and
energy providers to vehicle manufacturers and end users. According to
Alpitronic, the UL approval confirms that the HYC400 delivers both the promised
charging performance and the required safety level, helping to build trust as
ultra-fast charging scales into everyday use.
Part of a global testing ecosystem
The EV Charging Test Center in Neu-Isenburg is part of a
broader international network of UL Solutions facilities dedicated to
supporting the electrification of transport. In Europe, this includes
specialised battery testing operations in Aachen and a microgrid and
distributed energy resource laboratory in Madrid. In the United States, UL
Solutions operates advanced EV charging laboratories in Northbrook, Illinois,
and Fremont, California.
Most recently, the organisation expanded its capabilities
with the opening of the North America Advanced Battery Laboratory in Auburn
Hills, Michigan — one of the largest battery testing and development facilities
in North America. Together, these sites form a global infrastructure aimed at
ensuring that the rapid expansion of electric mobility is matched by rigorous
safety, quality and performance standards.
With the HYC400 now UL-certified, Alpitronic positions
itself squarely at the intersection of ultra-fast charging, regulatory
compliance and international scalability — a combination likely to become
increasingly decisive as 400-kW charging moves from flagship installations into
the backbone of global EV infrastructure.
Competitive landscape in high-power DC charging
While Alpitronic’s UL-certified HYC400 reflects a
significant step toward market readiness, other suppliers are also expanding
their portfolios in the high-power DC segment.
For example, ABB E-mobility’s A400 All-in-One charger
delivers up to 400 kW with dynamic power sharing across two outlets, designed
for fleet and public charging applications. Siemens’ SICHARGE D platform
similarly targets the 400 kW class with continuous output and modular
configurations, including the ability to serve multiple vehicles simultaneously
through dynamic allocation of available power.
This competitive environment underscores that in the race to
scale ultra-fast charging infrastructure, performance, modularity and global
certification increasingly shape procurement and deployment decisions.
