Delta Launches New 100kW DC City Electric Vehicle (EV) Charger

An EV fast-charging solution with efficient charging.

Delta, a global leader in power and thermal management solutions, today announced the launch of its brand-
new 100kW DC City EV Charger, a solution featuring leading 94% efficiency and a high availability modular
design to offer EV drivers a 100km driving range with roughly 15 minutes of charging. This new product,
which is also capable of charging two EVs simultaneously, and Delta’s own EV Charging Infrastructure
Management System, create the proper ecosystem to address the current increasing demand for fast EV
charging in metropolitan areas. The 100kW DC City EV Charger is expected to reach the market in Q4 2019.

To enable fast charging, the Delta DC City EV Charger provides high power conversion and high power
output by leveraging Delta’s industry-leading expertise in high-efficiency power electronics technology. Thus,
the system is supported by Delta’s own power modules which allow for high AC-DC energy conversion
efficiency up to 94%, a level that favors electricity savings. The 100kW high power output can deliver up to
100km of travel distance with just 15 minutes of charging. The system also offers dynamic load distribution,
network connectivity, IP55-rated enclosure protection, built-in RFID reader, and easy back-end integration to
optimize the operational efficiency of charging services. These capabilities make it a highly versatile and
viable EV fast-charging solution for public charging stations, parking lots, shopping malls, commercial offices,
hotels as well as fleets.

The DC City Charger’s modular design enables high availability of charging services by making power
module replacement easy and ensuring continued operation in the event of power module failure. This
means that when a single module fails, other modules will continue to supply power without the overall
operation being affected. Furthermore, operators only need to replace failed modules during maintenance,
which significantly reduces maintenance times and downtime costs while ensuring high availability for
charging stations. As a result, high availability and efficient performance contribute to the optimization of
operational benefits.

The DC City EV Charger can be equipped with CCS1, CCS2, CHAdeMO and GB/T charging interfaces to
make it suitable to most EVs on the market. It can conduct simultaneous charging of two EVs with its
dynamic load distribution, ensuring that the appropriate output is automatically distributed according to the
actual power demand. This optimizes charging efficiency when two EVs are charged at the same time, thus
improving the utilization and parking space turnover at charging stations.

Other key features of the DC EV Charger include:

  • A relatively compact size (590 x 1500 x 800 mm) to make it suitable for space-constrained areas
    where land cost and population density are high.
  • A sturdy and durable enclosure protection against dust and water (IP55) and external mechanical
    impacts (IK10), thus, suitable for outdoor or basement environments.
  • Built-in RFID reader compliant with ISO 15118 for user identification and easily integrated to member
    management and payment systems.
  • OCPP communication protocols with Ethernet, wireless, mobile and Bluetooth connectivity options.
    This means that charging status information can be integrated with any back-end management
    system that supports the OCPP data format. Both front-end and back-end integration are thus very
    easy for operators, regardless of whether they select Delta’s EV Charging Infrastructure Management
    System, use their existing system, or integrate data into smart building and energy management

Delta’s 100kW DC City EV Charger not only meets fast-charging demand in metropolitan areas, but it also
offers the benefits of operational optimization and flexibility for extended applications. A 50kW model is also

Delta will be demonstrating the new DC City EV Charger at eMove360° Europe, to be held at Munich Messe,
Hall A5, stand 403, from 15 to 17 October. For more information, please contact your local Delta sales
