With all the interest in Sustainability and Climate change, one Cobourg resident is sold on one of the current trends – Electric Cars. Harry Nash and his wife Linda are planning an “adventure” – they are driving their 2017 Tesla Model S from Cobourg to see family on the West Coast of the U.S. then the South Coast – see the map below. In a way, this shows that with the right car, there is no need for range anxiety. But since Harry is an organized person, he has mapped where he needs to stop, how long he needs to wait for recharging and how much charge there will be at any point in time. Harry gave me his data and I have extracted some interesting facts.
Trip Statistics (distances in km)
|Length of Trip||11,667|
|Number of re-charge stops||70|
|Average distance between stops||167|
|Maximum distance between stops||259|
|Average charge time||0:29|
|Average charge cost||$8.80|
|Total Charge cost||$616|
|Minimum charge when recharging required||10%|
|Average charge at end of re-charge||70%|
|Maximum charge at end of re-charge||98%|
|Average time between stops||1:23:28|
|Maximum stop time||1:01|
|Minimum stop time||0:13|
For the Tesla model S, recharging is free – above costs are for other models. Harry estimates an internal combustion engine would cost $1300 to refuel. If you are looking to charge your Tesla Model S for free, there is a Tesla SuperCharger in Port Hope – behind Harvey’s on Telephone Road. Although they are lower power, there are two charging stations in Cobourg – one at the Best Western and the other adjacent to LUSI’s office on Division Street.
Harry is assuming his average travelling speed will be 120km/hr but did not say how many overnight stops he’s making or how many kilometers he’ll travel each day.
Here is some more info on Electric Cars that Harry supplied:
The Tesla is recognised by every safety testing establishment in North America as the safest vehicle ever. Top speed on the Tesla model S is 230Km/h. Zero to sixty time is just over 3 seconds, making it one of the fastest production vehicles in the world. Since there is no engine, there are no oil changes, fan belts, timing belts, water pumps etc., etc, thus making the car extremely inexpensive to operate. Harry has installed a dryer plug in his garage. He plugs into it before bed and has a full battery when he wakes up in the AM (charging at the low electricity rate). His vehicle has a 100 KWh battery, giving approx. 520 Km range.
Motor Trend Magazine made it the car of the year in 2013. This year, the same magazine came out with the statement that the 2013 Tesla Model S is the best car of all that they have ever tested since 1949.
Given that 50% of all petroleum is used in the transportation industry, and that the battery industry is working overtime constantly to supply the needs of manufacturers, it is easy to understand why big auto and big oil are not happy.
Downside is cost of the vehicle. A Model S is not a good example, since it’s top of the line, but the Model 3 can go for as little as $46,000.
Harry and his wife are heading off to include the Christmas/New Year period with family so will be leaving in the next week or so.

Report on Actual Trip
The original route went over the Rockies in Winter and Harry was advised against that. So in the end the trip went via Albuquerque to San Antonio and missed California. Here are some trip statistics:
|Driving Time||67 hours|
|Charging Time||21 hours|
|Total Trip Time||89 hours|
|Total Energy Used||1,547 kWh|
|Average Efficiency||211 Wh/km|
Harry also supplied details of his stops. Download details here.
Cobourg to San Antonio = 54 h 3 min (4,523 km); Return = 35 h 10 min (2,878 km); Total: 89 h 13 min (7,401 km)
Fuel Saving compared to gasoline engine (ICE car): Cobourg to San Antonio = $587; San Antonio back to Cobourg = $374; Total: $961
Estimated gas savings assumes Supercharging cost of $0.26 per kilowatt hour. Gasoline cost assumes 11.8 liters per 100km at $1.10 per liter. Local costs and real world results may vary.
If required to pay for charging, the cost of the trip is estimated as $400 for an EV and up to $1300 for an ICE car. If charging at home, the cost for that much power would range from $100 to $200, depending on the time of day you charge your car.
Power cost if at home
|KWh used||Peak Time
|Energy Used on trip 1547||$201.11||$100.56|
Lessons Learned (by Harry)
- Don’t attempt to charge at Collin St Bakery on a Sunday after church. The pious are charging then!
- Tesla charging stations are vulnerable to unserviceability and vandalism.
- Self-drive technology is in its infancy. As we are told- don’t trust it yet.- especially in construction areas.
- Tesla navigation systems are very good.
- Computers have bugs.
