An electric vehicle (EV) is a vehicle that uses one or more electric motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with a battery, solar panels, fuel cells or an electric generator to convert fuel to electricity. EVs include, but are not limited to, road and rail vehicles, surface and underwater vessels, electric aircraft and electric spacecraft.

EVs first came into existence in the mid-19th century, when electricity was among the preferred methods for motor vehicle propulsion, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time. Internal combustion engines were the dominant propulsion method for cars and trucks for about 100 years, but electric power remained commonplace in other vehicle types, such as trains and smaller vehicles of all types.

In the 21st century, EVs have seen a resurgence due to technological developments, and an increased focus on renewable energy and the potential reduction of transportation’s impact on climate change and other environmental issues. Project Drawdown describes electric vehicles as one of the 100 best contemporary solutions for addressing climate change.

solarboat

An electric boat that runs virtually endlessly on solar power –  that’s the dream that’s been driving David and Alex Borton for the last 17 years. Since 2004, the father-and-son team has been working to fulfil their vision, building several custom, patented, solar-electric boats under the brand name of Solar Sal.

This summer, the two of them completed what they believe to be the first-ever solar-electric boat voyage from Bellingham, Washington, to Juneau, Alaska.

They departed on Tuesday, 25 May, in their 27-ft wooden hull solar boat Wayward Sun and made landfall at Ketchikan, Alaska, 13 June, then continued up the coast at a more leisurely pace to Glacier Bay and Juneau, concluding the voyage on 8 July.

The electric boat is powered 100 per cent by solar energy with no fossil-fuel combustion engine at all on board. “People always ask us if we have any gas or diesel back up,” said Alex Borton, “but the sun rises every day. If our batteries get too low, we just wait.”

Wayward Sun, built by Devlin Boat in Olympia, WA, is propelled by a Torqeedo Cruise 4.0 electric pod drive with six Torqeedo Power 24-3500 lithium batteries.  There is a separate 12-volt system for lights, electronics and other DC-powered systems and an inverter for occasional AC loads, like making waffles. The batteries are charged from a 1700-Watt array of solar cells on the boat’s rooftop.

Better than expected

“The solar-electric system has more than exceeded our expectations,” said Alex Borton. “During the 45-day passage from Bellingham to Glacier Bay to Juneau, we were underway for 38 days. We averaged 32 nautical miles per day at an average speed of 3.7 knots. While some days we stopped early or left late because of weather, there were only two full days we didn’t travel at all due to high winds or dense fog.

“Even on a completely overcast day this time of year, we can travel at 2-3 knots during daylight hours without drawing on our batteries at all,” Borton said. “With direct sunlight, we can do 5 knots or more all day without any battery use. Most of the trip was overcast and it rained a lot. Some days we travelled slowly because we had to; other days we travelled slowly and charged the batteries while underway.”

No limits

“Most electric boats on the market today are limited by their battery capacity, which means they have to return to shore power to charge,” explained Borton. “Until recently, solar panels and batteries were just not capable of severing the tie to shore power, so it was only functional for extending range or for partial charging. But now, thanks to advances in solar cells and Torqeedo’s efficient electric drives and high-capacity batteries, it’s possible to produce a solar boat with reasonable speeds and accommodation that can continuously cruise without ever charging from the shore. If I had more time I would keep going for another 1000 miles.”

They navigated from Bellingham to Ketchikan using the inside passage, anchoring at night since they were not permitted to go ashore in British Columbia due to Canadian Covid-19 travel restrictions. “That was no problem for us,” said Borton. “We had lots of food, a cosy cuddy for sleeping below deck. And, of course, our solar boat doesn’t need refuelling.”

“This is an important validation of state-of-the-art solar-electric boat propulsion technology, and we have enjoyed following their daily progress on their blog,” said Mary Jo Reinhart, director of OEM and retail sales, Torqeedo, Inc.

ev demand electric car

European consumers are increasingly turning to electric vehicles as focus turns to the industry. Several initiatives from governments are inspiring the ev demand from consumers.

According to data acquired by Finbold, the demand for new passenger battery electric (all-electric) vehicles across Europe surged 231.58% between Q2 2020 and Q2 2021, from 63,422 to 210,298. The figures reflect a triple growth in demand for all-electric vehicles.

Elsewhere, demand for the hybrid electric vehicle also spiked by 213.54% to 541,162 representing the biggest growth for all new passenger vehicles in Europe. In total, the electric vehicle registration as of Q2 2021 stands at 751,460, a growth of at least three times from the Q2 2020 cumulative figure of 236,015.

During the period, plug-in hybrid vehicle demand surged 255.8%, from 66,252 to 235,730. Natural gas vehicles recorded demand of 41.84% from 9,515 to 13,497.

Furthermore, during the first half of 2021, battery electric vehicles recorded a share of 6.7% under new passenger cars by fuel type in the region. Hybrid electric vehicles had a share of 18.9%, while plug-in hybrids stood at 8.3%. Petrol accounted for the highest share at 42%, followed by diesel at 21.7%. Natural gas had a share of 0.5%.

Government incentives spurs EV demand

The report explains how different government policies contributed to the surge in demand for electric vehicles in Europe. According to the research report:

“For instance, when the coronavirus pandemic hit, most governments across the region focused their stimulus packages on companies that are operating in line with fighting climate change. Notably, a big part of the support focused on incentives for consumers to buy EVs, creating a surge in demand.”

Additionally, the demand emerged at a period, the electric vehicle industry suffered a chip shortage due to supply chain constraints due to the pandemic. However, the full impact will manifest later this year.
