FAQ
Q: What input power connection is required to operate this charger at full capacity?
A: The unit requires a standard 3-phase AC 400V (±20%) grid connection at 50/60Hz. To achieve the maximum 40kW DC output, your power supply line must be capable of delivering the corresponding AC current (approx. 60–70A per phase).
Q: Which EV charging connector standards do you support, and can we switch connector types?
A: We offer factory-installed connector options for CCS1 (North America/Japan), CCS2 (Europe/Australia/SE Asia), GB/T (China), and Tesla (NACS).
Q: How fast can the 30kW or 40kW model actually charge a stranded electric vehicle?
A: A 30kW–40kW DC unit delivers direct current directly to the battery, bypassing the vehicle's slow onboard AC charger. It typically provides roughly 100–150 km (60–90 miles) of driving range in 30 to 45 minutes, making it ideal for rapid emergency top-ups or fast turnarounds in service bays.
Q: Can a single technician easily load, transport, and deploy this charger in an emergency vehicle?
A: Absolutely. Measuring 290 × 670 × 605 mm, the compact cabinet fits inside standard SUV boots, commercial vans, or rescue truck compartments. Built with heavy-duty castors and an ergonomic pull handle, a single operator can roll out and activate the charger within 3 minutes.
Q: What international safety certifications and testing standards does this product meet?
A: The charger holds full CE compliance and adheres to IEC 61851 and IEC 62196 international EV charging standards, ensuring smooth customs clearance and regulatory approval across Europe, Latin America, Asia, and the Middle East.
