Second-generation Volvo C30 Electric practical: AC trumps DC

Let’s it: electric cars can’t from empty to full as quickly as petrol ones. But most electric cars on today can easily drive 60 and 80 miles on a full charge recharge at night when asleep- it’s not usually a

While overnight charging most of your EV’s however, there are occasions you need to top up during the day. DC rapid charging now at various service stations across the UK, be forgiven for thinking that minute refuelling is the answer.

But as I this week, availability and sometimes trump speed.

Swedes

It’s Wednesday and I’m sitting in a briefing at Volvo headquarters in Gothenburg, I, and three other journalists, are given a quick technical by Volvo engineers on the second C30 electric hatchback.


Started back in 2009, all-electric C30 test fleet covered hundreds of thousands of across Europe, providing of Volvo’s business lease their first experience an electric car. Being the first generation C30 electric were also hardy, of operating in bitter Arctic without batting an electrical

Building on the successes of the first-generation the 100-strong fleet of second Volvo C30 Electrics will a slightly more powerful and power electronics from electronics firm Siemens, but the same battery pack, elements and winter-ready kit as their

What’s different however, is how it Unlike the first generation, was kitted out with a puny 3.3 on-board charger, the second-generation have a 22 kilowatt on-board from Swiss firm With the right charging it can replenish the C30’s battery from 30% empty to 90 per cent in as little as 90 minutes.

Cost

I what some of you are thinking: 90 That’s slow! Ha! The Nissan Citroen C-Zero, Mitsubishi Peugeot iOn and Renault ZOE all charge faster!

You’d be right. The four can charge to 80 per cent in 30 minutes using a suitable 50 CHAdeMO direct-current charging The ZOE can do something similar using a high-power 43 kilowatt AC rapid station.

But both DC and AC rapid charging rely on expensive, external stations capable of handling the power (400 Volts, phase at 64 or 125 Amps) needed to an electric car in under 30 minutes. of the amount of power involved, charging stations are normally time-consuming and expensive to install.

charging stations, like the 22 three-phase Type 2 (Mennenkes) now found at many locations Europe, are substantially cheaper to and install. Cheaper means of them, which not only redundancy when things go but also means less just to find somewhere to quickly.

It’s on-board

Volvo C30 Electric

like the Renault ZOE — can recharge at up to 22 kW using regular 2 charging stations as well as the expensive AC rapid charge detailed above — latest prototype is completely when it comes to charging.

Feed it 240-volt, 16 amp single-phase from a domestic charging and it will charge to full in 8 hours. Give it a 240-volt, 32 amp feed and it will charge in 4. phase, 11kW charging take around 2.5 hours to 90 per while the highest 22kW just 90 minutes.

All without to switch between different or cables.

Winning Flush

love to say that the C30 Electric I drove this week me away with its driving or tell you it’s coming to a near you soon. Sadly I the C30 second generation drives and like its predecessor, and Volvo has no to bring the C30 electric in its current to market.

But the demonstration of 22 kW charging technology has to me that it is the sweet spot for EV

While slower than the expensive DC and AC rapid charging 22 kW charging makes it possible to for lunch and recharge wherever a suitable three-phase power Since most places want to stop for 90 minutes like pubs, restaurants and — have enough to provide the required power major rewiring, it’s theoretically possible to use an ad-hoc source, like those big three-phase sockets you sometimes see in kitchens.

For that reason, hoping my next EV has three-phase AC, not DC as standard.
