People are often disappointed at the charging rate they get at DC chargers because the rating on the a DC charger can be misleading/not understood AND also the EV's charging curve affecting the charging rate. DC chargers are often labeled with some "maximum" rating under optimum conditions. Like a two-connector 360KW charger probably means a "maximum" of 360KW "shared", repeat, shared between the two connectors; not the ability to provide 360KW per cable whether the other cable is being used or not. Each connector will likely have power limited by the maximum "amps" draw allowed per connector with the source of the limit typically being the cable being limited to 200A. 200A cables are very common on DC chargers as they generally meet the charging requirements of "most" current day EV...plus, higher amp cables and associated charger equipment significantly increases charger construction costs. You can usually find the chargers cable amps limit by looking for a plate on the charger that will show charging voltage range (i.e., 150V to 950-1000V, 200-300amp, and I 've seen a few with 500 amps etc). Many times that label is kinda blocked from easy view under the point where the cable enters the cabinet. Other times it will be at the very top or bottom of the charger cabinet. And sometimes there is no label to be seen on the outside as the label is on the inside of the cabinet. But most of the time you can find a KW/Voltage/Current rating label on the outside. Look closely as to what the cable amps limit is.....200A is very common on most chargers currently in Thailand. So, at this 360KW charger with a 200A cable limit using a formula for Power which is "Power = Current times Voltage" when multiplying the charger upper voltage limited which is typically 950V or 1000V (lets says 950V) by 200A limit of the cable gives a max power of 190KW per connector before any power losses are considered. Power losses like cable heating, EV wiring/battery heating, etc. Adding the two connectors together allows the charger to call itself a 360KW charger Plus, the EV is probably "not" going to be requesting 950V even on a so-called 800V EV charging architecture. An 800V architecture actually ranges between approx 550V to 950V. The 800V name is more of a nominal valve, a nickname, tradename, etc. Like the Zeekr 7X with 100KWH battery has an actual 685V charging architecture....with the 685V architecture the max voltage it will request during DC charging is approx 790V. I arrive at that 790V number based on voltage needed to bring each 3.2V battery cell in the EV battery pack up to 3.65V full charge (full/100% charge for an LFP cell is 3.65V), Please remember this 790V number as I'll used it again later. So at this 360KW charger which is really only able to output 190KW per connector (before any losses are considered) it would need to be connected to an EV which can accept 190KW at the particular State of Charge (SOC) during the charging session....that is, does the EV's "charging curve" support 190KW at a certain SOC. Well, if for example charging a Zeekr 7X with 100KWH battery its charging curve (shown below) would support 190KW unless the EV was at a SOC of 80-85% and higher. And its 430KW max/peak rating is for a "very limited portion" of its charging curve...like only in the the 10-20% SOC ballpark...and most people don't let their charge get that low on a long trip. However, when multiplying 790V (that number I asked you to remember) times a 200A probable cable amps limit you get 158KW which is durn close to the160KW that mistral53 was getting on his 7X at a Spark 360KW charger. The design of a DC charger, whether it has 200A or 300A or 500A cable, whether the power is shared between connectors or not, whether the power modules are built right into the DC charger or are located in a separate power control cabinet, EV charging curve, and other factors can all make a difference in the actual charging rate a person gets. Having an EV with a high KW charging capability/curve is definitely a good thing....but being able to actually utilize that high charging rate capability can turn out to be a different story.
