ChargePoint Launches European Expansion With New InstaVolt Partnership

Originally published on CleanTechnica

ChargePoint has announced a new partnership with InstaVolt to install more than 200 ChargePoint rapid charging systems. This represents the first major milestone in its European expansion.

UK electric vehicle charging network InstaVolt has signed a contract to purchase more than 200 of ChargePoint Express Plus systems. These systems will be installed by InstaVolt along popular routes in the UK with an aim to enable drivers to quickly recharge their EVs on longer road trips.

As we shared back in January, the ChargePoint Express Plus charging system is a modular solution that allows operators to install the charging station and then increase the charging speed of the systems as more vehicles capable of fast charging enter the market. This is critical because it gives operators confidence that the initial investment will not be lost as technologies change over time, but instead allows them to change with the times and increase charging speeds up to 400 kW … which is 3 times faster than any vehicle on the market today.

Tim Payne, CEO at InstaVolt, said of the partnership:

“We are delighted to partner with ChargePoint to deliver a best in class EV charging infrastructure. We own, install and maintain rapid electric vehicle charging units all over the country, giving landowners the opportunity to earn a rental income by housing them, and giving EV drivers access to the fastest charging available.

“ChargePoint will fulfill two important criteria for us: the charging units are future-proofed so the units can be configured to meet the precise requirements of any site and can be scaled incrementally as demand for higher rate charging increases. This is particularly important as EV manufacturers begin to bring out new models with increased battery capacity. We are also committed to making sure the units are working 24/7 and so the reliability of the ChargePoint solution is one of the cornerstones of our offer.”

The move into the European market for ChargePoint and this new partnership with InstaVolt represent major milestones in the rollout of the fast charging network of the future. To date, the fastest non-Tesla charging stations available top out at 50 kW, whereas these new ChargePoint units allow for dramatic expansion in the future.

This turns the notion of installing 6.6 kW chargers that will be out of date in a few years on its head. For the first time, it gives the public the confidence they need to buy an EV with the knowledge that public chargers exist that can support them over the life of the vehicle. Whether consumers will need to own vehicles in 10 years is another story altogether. …

EV Drivers Want (or Require) Superfast Charging

Worth highlighting here is that many of today’s EV drivers demand or at least greatly desire superfast charging in their next EVs. Depending on the type of electric vehicle they drive today (a non-Tesla fully electric car, a Tesla, or a plug-in hybrid) and where they live (Europe or North America), 32–92% of the respondents we surveyed said they required superfast charging in their next EV.

Survey results from our new EV report. Responses came from over 2,000 EV drivers across 26 European countries, 49 of 50 US states, and 9 Canadian provinces. Responses were segmented according to region — North America vs Europe — and type of electric car — plug-in hybrid vs Tesla vs non-Tesla fully electric car.

Looking at desires instead of requirements, the figures ranged from 45% (European non-Tesla fully electric car drivers) to 86% (North American Tesla drivers).

EV Charging — The Time For A Single Fast-Charging Standard Is Now!

The EV charging network is the gas station network for EV owners — the only place to fill up and top off when out on the town, driving around the fringes of an EV’s range. What’s more, charging up an EV takes longer than fueling up an ICE vehicle, so the quantity and availability of charging stations makes a huge impact on the functionality of EVs. To further complicate matters, the growing fleet of plug-in hybrid electric vehicles (PHEVs) that don’t have the same “need” to charger can frequently be found charging at public EV charging locations, blocking out battery electric vehicle (BEV) drivers that, as a result, might not be able to get the charge they need to continue to their destination.

As BEVs and PHEVs increase in popularity, the current public EV charging infrastructure will also need to be scaled up to support the fleet. The lack of an EV fast charging standard further complicates the landscape, fragmenting the already struggling infrastructure with several standards competing for dominance, and manufacturers are drawing lines in the sand and picking teams to determine which standard will reign supreme.

Where We Came From — Level 2 Charging

With the initial deployment of EVs, what we now call Level 2 chargers were deployed far and wide to incentivize the public to purchase electric vehicles. These chargers provide charging rates of 6.6 kilowatt-hours for each hour of charging. In a Leaf, that equates to around 24 miles of range per hour of charging. These chargers were a fantastic start at developing a public charging network and gave early adopters the confidence to purchase a $30,000 vehicle with a reduced range.

Level 2 public chargers allowed people to extend the practical range of their EVs with just a few hours of charging required to top off their charge before heading on to another destination. Level 2 chargers are now installed in garages of many EV owners and the public network of chargers has only continued to grow as EV adoption has increased.

Building a Better System — Early DC Fast Charging

To complement these chargers, Level 3 chargers — or DC fast chargers — have started popping up. Level 3 chargers brought a significant advantage to the table in terms of charging speed and were able to push ~19 kWhs in a 30-minute session, equating to the addition of roughly 80% of the charge or an extra 76 miles of range. Charging rates slow as the battery nears the 90% full range, so, your mileage may vary.

DC fast chargers have grown into the gas stations of the EV charging network in most areas, as they allow ~80% charge in the time it takes to enjoy a cup of coffee or grab a bite to eat.

Similar to early Level 2 chargers, Level 3 chargers are expensive, with installations requiring significant electrical infrastructure in addition to a hardware cost upwards of $100,000 each in the US. Due to the high capital cost required to install Level 3 chargers, early installations have been slower and mostly implemented by companies dedicated to charging infrastructure likeNRG EVgo and ChargePoint. These chargers started popping up in major cities, then made their way into smaller cities across the nation.

DC Fast Charging Today

Which brings us to today. In the southwestern United States, we have a healthy network of Level 2 chargers supported by a sprinkling of Level 3 DC fast chargers. On top of this mature network, EV sales have ramped up and are weighing heavily on our primarily Level 2 charging network. Many modern EVs are equipped with fast charging capability, with many supporting higher speeds than the current networks even provide. As we approach the next step change in EVs — with ranges of 200 miles requiring batteries of 60 kilowatt-hours and more — we are again approaching a point where even our fastest chargers today will not meet the needs of the masses.

CHAdeMO

CHAdeMO plugs are the size of a large firehose, making its charging cables unwieldy, and it is the fast charging adapter of choice for the Kia Soul EV, Citroen, Mitsubishi EVs, Peugots, and of course, Nissan and the established Leaf (as an option). CHAdeMO offers charging speeds of up to 70 kW, with real-life 30-minute charging sessions delivering just over 19 kWh of charge or around 75 miles of extra range (on a Nissan Leaf). CHAdeMO is seeing extremely rapid adoption in Japan, with around 5,500 stations deployed today (crazy considering how small Japan is!). The US — specifically, California — is ramping up deployment of CHAdeMO stations quickly as well, where over 1,300 stations have been deployed.

SAE Combined Charging Solution

Competing with CHAdeMO for the DC fast charging crown is the newer SAE Combined Charging Solution (aka SAE Combo, or CCS), which is a standard J1772 plug with 2 additional DC fast charging ports below it (hence the combo moniker). This newer standard is the fast charging standard of choice for Audi, BMW, Daimler, Ford, General Motors, Porsche, and Volkswagen. Most notably, this port can be found on the BMW i3, the Chevrolet Spark EV, and the Volkswagen eGolf. Combo adapters are similar in size to CHAdeMO, though due to the utilization of the existing J1772 plug, only require a single port on the car, whereas CHAdeMO requires 2 separate on-vehicle ports.

These Combo plugs offer maximum speeds of up to 90 kW (DC Level 2) with theoretical speeds of up to 240 kW. In real life, SAE Combo charge rates are comparable to CHAdeMO, delivering roughly 80% of the range of ~100 mile EVS in a 30-minute fast charging session.

Supercharged

Finally, the Tesla charging format supports all charging levels from Level 1 (normal wall outlets at 110 volts) up to the Tesla-only DC Supercharging network which boasts the fastest broadly available charging speeds, cranking up to 400 miles of range per hour (design rate) with a real-world miles delivered in 30 minutes of Supercharging sitting at 170 miles. This does not scale up linearly (170 x 2 = 340 miles of range delivered per hour), as charging slows when the battery approaches capacity — but it’s still extremely impressive and much faster than any other fast charging standard with a substantial deployed footprint.

The Tesla charging standard is also much more compact than the other standards and can be used for all charging speeds — from 110v wall charging @ 15 amps all the way up to Supercharging.

The Road to the Future

Where to from here? Ultimately, the market will decide which manufacturer and, thus, which standard prevails. Manufacturers are realizing the negative sales impact the current, scattered public charging network is having and building out branded charging networks. Much like the VHS vs Beta or the HD-DVD vs Blu-Ray battles of the past, fragmented landscapes rarely last for long. We will likely converge on a single standard, but the longer the transition is drawn out, the more consumers — and EV adoption rates — will suffer. We need a fast charging standard now to give manufacturers and consumers confidence in EVs long into the future.

Several clear paths exist — though, with sides having already been chosen, no option will be pain-free. An NGO or charging alliance could be formed as a neutral self-governing body to select a dominant standard moving forward. Though, this is challenging as these organizations cost money and offer little financial upside for participants. Government mandates can also create results and that feels like what may be required to unify manufacturers as an effort to protect consumers from non-value-added infrastructure fragmentation.

Whatever the path forward, the time for action is now. Consumers are calling out for a single EV fast charging standard to carry us several decades into the future….
