Right here at CleanTechnica, we write so much about EVs, which means largely land-based electrical automobiles: automobiles, vehicles, buses, bikes, e-bikes, and occasionally even electrical tractors. Sufficient posts have been made concerning the Polestar EVs they’ve their very own tag on the positioning. Sometimes, we additionally write about electrical boats, however that is the primary time we’ve printed an article about an electrical boat getting a brand new battery system for an electrical automotive, particularly the Polestar 2 battery.
Yep, that’s proper, the Candela C-8 now has the Polestar 2’s 69 kWh battery, relatively than the 44 kWh battery it got here with beforehand. With the brand new bigger battery, the C-8’s vary is as much as 65 miles touring at 22 knots; beforehand it was 50 miles. The brand new battery can fast cost in as much as one hour, with the unique battery this era was as much as 4 hours.
The C-8 electrical boats with the Polestar battery methods are scheduled to enter manufacturing within the first half of 2023. The C-8 makes use of hydrofoils to cruise above the water floor as soon as it reaches a sure velocity. Within the press launch, Candela wrote that at this cruising velocity the propulsion and battery system are fairly environment friendly utilizing solely 23 kW/30hp repeatedly.
If you’re unfamiliar with the C-8, listed below are the specs:
Size: 8.5 meters (28 toes)
Width: 2.5 meters (8.2 toes)
Weight: 1700 kg (3850 lb)
Capability: 8 passengers
Propulsion: 69 kWh battery (Polestar 2 Customary vary, Single motor)
Polestar DC charging, 11 kW 3-phase AC charging
Sustained high velocity: 27 knots (31 mph)
Anticipated vary: 57 nautical miles (65 US miles) at 22 knots
Candela’s Mikhail Mahlberg answered some questions concerning the new battery system and vary for CleanTechnica.
How did the Candela and Polestar partnership come about?
We have been really launched to one another by Peter Carlsson, the founder and CEO of Northvolt, a buddy of Gustav Hasselskog, our founder. An ideal instance of the collaborative Swedish EV atmosphere.
The Candela C-8 with a bigger Polestar battery with a brand new real-world vary of as much as 65 US miles at 22 knots. How did you check and decide the brand new vary?
We’ve calculated this from the true world vary of Candela C-8 in numerous circumstances.

Would the vary cruising at 10 knots be about 100 miles or a little bit extra?
Far much less! At 10 knots, any boat might be at its least environment friendly velocity. That’s the place typical boats begin to method the planing threshold, so both you go under 5 knots or above take-off velocity of 16 knots. There’s no electrical boat in the marketplace that may obtain 100 miles at 10 knots.
The brand new Polestar 69 kWh battery will be fast charged in about one hour, however is that to 80%?
10-80% in 40 minutes.
What’s the Polestar battery’s chemistry?
Lithium-ion.
Does the C-8 include a charger appropriate for the brand new battery?
Sure! Onboard 11 kW AC charger.
What’s the value of the C-8 with the brand new Polestar battery?
Similar as earlier than – US$395,000. Higher boat, similar value.
What’s the new battery’s anticipated lifespan?
It is going to seemingly final for a lot of, a few years, provided that electrical boats are used lower than automobiles.
When the boat is just not in use, is it good follow to trickle cost it to make sure the battery is just not allowed to go to zero cost?
Precisely, batteries are finest saved at round 20-60% or so for longevity.
The place is the C-8 obtainable to buy?
Throughout the globe, we promote internationally, and have gross sales areas in California, France, Stockholm, and companions in most of Europe and shortly in LA and different locations within the US with demo boats.
