Grasen DC fast chargers charge faster than Level 2 (AC) chargers and are easy to use. The best time to use DC fast charging is when the driver need a charge right away and you’re willing to pay a little more for the convenience—like on a road trip, or if you have a low battery but are pressed for time. DC Fast charging stations are very suitable to installed at EV charging point, parking lot, underground garage, highway service station, bus charging station, EV truck charge stations and many other places.
DC Fast Charging bypasses all of the limitations of the on-board charger and required conversion, instead providing DC power directly to the battery, charging speed has the potential to be greatly increased. Charging times are dependent on the battery size and the output of the dispenser, and other factors, but many vehicles are capable of getting an 80% charge in about or under an hour using most currently available DC fast chargers.
What is a DC Fast Charger?
DC fast charger is a dedicated DC device that connects electric vehicles directly to the AC/DC grid (power) side and is installed with a control guide to ensure reliable connection between the charging post and the electric vehicle and charging safety, etc. It also integrates functional modules such as human-machine interaction system, charging management system, local and remote communication interfaces to facilitate the use and management of this dedicated equipment.
The DC charging station provides DC electric energy to the battery pack of the electric vehicle, and under the management of the on-board BMS system, the energy recharge of the electric vehicle is finally realized.
Features of DC Fast Chargers/ Charging Stations
Over-Current Protection Features is the most advanced Electric Vehicle Charging Station currently available. Its modular design construction allows for free configuration of power modules and electrical components - increase the output power from 60kW to 300kW, application of a Ethernet/WiFi/3g/4g communication or RFID card reader.

DC fast charging is essential for high mileage/long distance driving and large fleets. The quick turnaround enables drivers to recharge during their day or on a small break as opposed to being plugged in overnight, or for many hours, for a full charge.
Older vehicles had limitations that only allowed them to charge at 50kW on DC units (if they were able to at all) but newer vehicles are now coming out that can accept up to 270kW. Because battery size has increased significantly since the first EVs hit the market, DC chargers have been getting progressively higher outputs to match – with some now being capable of up to 350kW.
Currently, in North America there are three types of DC fast charging: CHAdeMO, Combined Charging System (CCS) and Tesla Supercharger.
All major DC charger manufacturers offer multi-standard units that offer the ability to charge via CCS or CHAdeMO from the same unit. The Tesla Supercharger can only service Tesla vehicles, however Tesla vehicles are capable of using other chargers, specifically CHAdeMO for DC fast charging, via an adapter.
How fast is fast charging?
The charging time is largely affected by the following factors:
1.Battery capacity - the larger the capacity, the longer the charging time
2.Charging post power
DC charging station, in the car DC charging port can be loaded under the current, the higher the charging pile power, the higher the maximum current, the shorter the charging time.
3.Take BYD E6 for example, battery capacity 82kWh
If adopting DC charging pile, charging current 130A, 2 hours full.
When using DC charging pile, the maximum current of the charging pile prevails.
When charging at 30kW charging pile (maximum current 60A), 120A/60A=2h.
4.How far can I run after charging for one hour?
The battery capacity and wear and tear of the electric car determine how far the car runs, the charging pile only affects the charging time, the actual each car is different. Using 30kW DC pile charging, one hour can charge 24 degrees, enough for 168km range.
