Rapid EV Charging Progress by 2025: Speedier Refueling for Electric Vehicles
In the rapidly evolving world of electric vehicles (EVs), several companies are making significant strides in improving charging solutions. Here's a roundup of some of the latest developments in this field.
Amperfied and Partners Pioneer Dynamic DC Charging
Amperfied, a subsidiary of Heidelberg Druck, in collaboration with ChargeOne, Vaylens, and other e-mobility companies, has unveiled the Amperfied Dynamic DC charging solution. This innovative technology ensures efficient energy distribution to connected vehicles, thereby reducing underutilized capacities in central power units.
Kehua Tech's 40-kilowatt Charging Module
Kehua Tech, a Chinese company specializing in high-performance charging, has developed a 40-kilowatt charging module for fast charging stations. This module, which achieves a peak efficiency of 97% and a standby power consumption of only 7.5 watts, utilizes silicon carbide (SiC) technology.
Bidirectional Charging for Cost Reduction
Bidirectional or intelligent charging can potentially reduce costs by allowing EVs to act as energy storage systems or power plants. However, the on-board charger and matching wallbox for bidirectional charging will only hit the market in two years.
Optimized Charging Stations from Elli and Kostal
Volkswagen's subsidiary Elli has evolved its Elli Flexpole charging station with the Plus addition, which allows DC fast charging up to 150 kW without grid reinforcement thanks to integrated battery buffering. The thermal management of the Elli Flexpole charging station has been optimized with new cooling circuits and an intelligent heat control system to reduce electricity consumption.
Kostal and its subsidiary Compleo Charging Solutions are presenting a complete AC-based system for bidirectional charging at the Power2Drive trade fair in Munich.
Scalable Charging Solutions from Sinexcel
Sinexcel, another Chinese company, focuses on megawatt charging and the scalability of charging parks.
Efacec's High-Power Chargers
Efacec offers two high-power chargers: the QC 120 DC charger, with a variable output power of 60 kW to 120 kW and a new Active-Boost function, enabling a current output of up to 400 amperes; and the HPC 240 and HPC 400, offering maximum charging powers of 240 kW and 400 kW, respectively.
German Manufacturers Embrace Bidirectional Charging
German manufacturers developing bidirectional charging systems and presenting at Power2Drive in Munich include Volkswagen Group and its subsidiaries Elli and PowerCo, KEBA Energy Automation GmbH, and Mercedes-Benz. These companies are focusing on pilot projects and technologies for bidirectional charging and energy solutions for private households.
The Future of EV Charging in Germany
In 2025, the VDA predicts around 666,000 pure electric cars will be newly registered in Germany, a 75% increase from the previous year. With these advancements in charging technology and the growing demand for EVs, the future of electric vehicle charging looks promising.
