Clearwater / Wells Gray Video online

In this video, we travel from Kamloops to Clearwater establishing the average energy consumption at 80 km/h. At the campground, we deal with our first charging challenge, before we set off hiking to three waterfalls in Wells Gray Park. Finally, we discuss our options for the upcoming ‘nail-biter’ trip from Jasper to Lake Louise.

Battery Power for Electric Car & Camping Trailer Charging Set-up

This is part 3 of our little 3 part series. In part 1, 100% Electric across Canada, I shared our plans on how to get across Canada without the extensive Supercharger network we’re used to from the US. In part 2, Solar Charging for Nerds, I provided tons of details on our solar panel and battery set up. To get the full scope of information, make sure you read  those two before reading this post.

Charging the Camping Trailer’s Batteries

The trailer came, as usual, with a lead-acid battery, which I replaced with a Lithium-Iron-Phosphate (LiFePo) battery. I disconnected the original battery charger as the LiFePo batteries will always be charged from the solar panels. At the campgrounds, we will plug in our car for charging, not the trailer. What an innovative concept ;-)…

Follow the thick blue line: The power comes from the 8 solar panels to the MPPT controller, which converts the roughly 80V of the panels to the battery voltage. From the MPPT controller, the power goes through the charge fuse the high-voltage solenoid and the battery main fuse to the battery. The programmable voltmeter reads the battery voltage and opens the high-voltage-solenoid to stop charging, once the maximum battery voltage is reached. You can still see the 110V charger next to the MPPT solar controller. We can connect it in a pinch should we need to ever charge the trailer battery from a power outlet.
