Levels of Charging (Approximate numbers)
Below are the various levels of charging. At your locations, you wil find.our Direct Current Fast Chargers (DCFC). That are much faster than traditional home chargers. you can find the different level of chargers below
|Cost per Charge||$||$$||~$45k|
|Primary Location||Residential||Residential, Public, Work||Public|
|kilowatts(kW)||1.3 - 2.3||3-19||50 and above|
|Range/hr charge||5-8 km/hr||29-45mi/hr||160-450km/hr|
|Ampere (Current rating).||20 Amp.||40 Amp||>500A|
|Time to fully charge 100 Mile/ 160km battery||17-25 hr||4-5 hrs||45 mins (or lower)|
|Drivers Served||1||3-4 or more||3-4 or more|
Rule of thumb: You are adding ~150kms of range if you charge your car using DC fast charger for 35 -45mins. Please note that this is an estimate, actual readings may vary and highly dependent on your battery condition and your battery capacity. The value provided here is with an assumption that you plugged-in your vehicle at 20% SOC and ending your charge at 80% SOC.
Modes of charging
Mode 1: Slow charging from a single or a three phase circuit
Mode 2 : Same as mode 1 but with some embedded EV protection
Mode 3: Slow or fast charging using a specific ECV multi pin socket with control and protection functions (SAE J1172 and IEC 62196)
Mode 4: Fast charging using some special charger tech such as CHADeMO and combined charging system (CCS).
Charging time Calculation
Charging time = Battery capacity (kWh)/ (charger power *0.9)
Battery capacity: Please refer your owner’s manual to determine the battery capacity of the vehicle or pick a value from the table above
Charger power : DCFC, please pick 50kW
Constant value ,0.9: Average power efficiency
For example, if you were to charge your Morris garage EV, your 0-100% charge time would be 44.5/(50*0,9) = 58 mins approx. to charge the vehicle,
However, to increase your lifetme of your battery our recommendation here is not to let your battery drain below 20% and /or charge beyond 80%.
