This may be sufficient for many typical use cases, but for long-distance travel, a one-hour charge simply isn't fast enough. Currently, the industry is developing DC high-power charging (HPC) to provide the same amount of charge (200 miles of range) in 10 minutes or less, producing an experience similar to filling up one's gas tank in an internal combustion engine (ICE) vehicle. The transportation and power utility industries are hard at work addressing this critical industry need, as summarized in Figure 2. Several groups—including the SAE International, the International Electrotechnical Commission (IEC), Charging Interface Initiative e. V. (CharIN), and the CHAdeMO association—are working to develop charging standards for electric vehicles worldwide. Multiple protocols and physical interfaces have been developed along the way by these industry-wide bodies. Work is underway to establish and accelerate megawatt DC charging, enabling even faster ELECTRIC VEHICLE CHARGER TYPES * Based upon 30 kWh/160 km (100 miles) average of current passenger car applications Time to charge * (add 320 km / 200 miles) 3 – 3 0 ho u rs 2 0 m i nu t e s – 1 h o u r 1 0 m i nu t e s – 1 ho u r < 1 0 m i nu t e s AC Charging 3.7 - 43 kW • On-board charger (AC/DC conversion) • At home / work / topping o• while running errands Type 1 North America South America Japan Type 2 Europe Australia New Zealand GB / T People's Republic of China Megawatt DC Charging 1 MW+ (under development) • Dedicated high-power charging station • Requires active cooling • Similar to traditional refueling experience • Ideal for commercial vehicles Interface not yet defined TESLA Supercharger DC Charging 50 – 250 kW • Proprietary charging station • Bypasses on-board charger • Charge during co•ee / meal break TESLA Proprietary DC Fast Charging 50 – 150 kW (no active cooling) • Dedicated charging station • Closer to traditional refueling experience DC High-Power Charging 200 – 500 kW (requires active-cooled charging station) CCS1 North America South America CCS2 Europe Australia New Zealand Japan DC Japan GB / T DC People's Republic of China TESLA Proprietary Figure 2: Electric vehicle charger types. (Source: TE Connectivity) "refueling" of electric vehicles, especially for larger commercial vehicles like buses and trucks. While the exact implementation of a standard is still under discussion, it is certain that at some point in the not- too-distant future an ultrafast DC charging capability, with power transfer beyond 500kW, will exist. Ensuring that vehicles are ready to take advantage of megawatt DC charging cannot wait until the standard interface is defined. Advanced connectivity technology investments need to be made, and solutions need to be developed now in order to be ready to meet the market needs of the future. Vehicles Face Technical Challenges Related to Megawatt DC Charging Connectivity Will vehicles be ready to handle 500kW charging? What about 1MW and beyond charging? Although the need to be able to charge a vehicle in minutes rather than hours is apparent, the way to address this requirement safely and effectively is not as
