SAP talks e-mobility!

I visited SAP’s facilities recently on their energy efficiency day and talked to them about their e-mobility initiatives and the rollout of their 16 Coulomb Technologies electric vehicle level 2 charging stations for their employees.

Tom Raftery: Hi everyone! Welcome to the GreenMonk TV. With me, today, I have Geoff Ryder from SAP and Henry Bailey also from SAP. Guys, we are at the SAP headquarters, here, in California, Palo Alto, because Geoff ?

Geoff Ryder: So, we started earlier this year taking a survey of all of our employees and are they interested in electric vehicles. It turned out they are. About 200 said they are in the market for one. So, how can we deal with that as a company? We can take advantage of that to show sustainability, thought leadership, we can also make this appealing to our employees, appealing place to work. So, you?re seeing today the culmination of our planning process. We are deploying 16 Coulomb Technologies charging sessions. These are level 2 charging stations, they?ll be across campus. And we?ll also —

Tom Raftery: Level 2 charging stations, means what?

Geoff Ryder: It?ll be 240 volts, that?s the voltage that you run your dryer off of. So, that?s very capable. It can charge the battery in a faster time than if you trickle charge with 120 volts. So, we think that?s probably the way it?s going to go. People will want to see that in their public charging option. Even at home, I think we?ll see you know Level 2 charging stations coming.

So, today, we?ve actually turned our first charging stations on and as you can see we have a small fleet of electric cars here.

We have our partners from Nissan with LEAF. We have a plug-in Hybrid Prius, we have a Chevy Volt, and further down, it?s hard to see, here but we have a CODA Automotive, a demonstration car.

Tom Raftery: Okay.

Geoff Ryder: Yeah.

Tom Raftery: Henry you?re involved with the e-mobility solutions, so ?

Henry Bailey: Correct.

Tom Raftery: What?s that exactly?

Henry Bailey: So, what we have done is we have looked at — as Geoff mentioned, we?ve got our employees interested in electric vehicles.

We also have a lot of our customers interested in the how to deploy electric vehicles primarily utilities looking at how do they manage the infrastructure when these vehicles start showing up in their service territories.

So, as people buy electric vehicles, they drive them home, now suddenly they?re plugging them into the Grid, which in some cases using the Level 2 charging station that Geoff described could look like another small home being plugged into the Grid.

So, the Utilities have a couple of opportunities, they need to look at how do they manage this new load coming on to the Grid and then also with the purchasing of energy by the home owner and maybe by third parties who are offering these charging stations at retail outlets, parking garages of businesses how do they, basically, settle those charges back to the consumer so that they can, basically, charge anywhere they want roaming freely around the country if you will.

Tom Raftery: The example being, if I go to the local supermarket and plug-in there, how does that charge appear on my electricity bill?

Henry Bailey: Exactly, but there may be different types of settlement options that the consumer wants. They may want it come back to their home energy bill as a separate line item, so they can see exactly what their energy usage is both when they plug it into their home as well as when they are roaming around to different shopping malls, grocery stores, as you are talking about.

They may also want to settle it to the credit cards, they may want to settle it to cell phones and have it as a part of that infrastructure. So, we?re looking at all different options and we also see businesses taking advantage because – take the mall, for example. If you can attract people with electric vehicles to come and stay maybe an extra hour or two giving them some sort of incentive to stay that hour or two by either the convenience and/or electricity at maybe low or no cost to them directly, then that entices them to stay longer, shop more.

So, they?re looking at it as a way to incent the customers to come and visit their place of business.

Tom Raftery: Excellent. Guys, thanks very much.

Geoff Ryder: Thank you.

The zero-emissions Nissan Leaf test drive

The Nissan Leaf

I love the idea of electric cars and have done for a long time.

Recently, one of my best friends Ray Flynn, proprietor of Flynns Garage (a Nissan Dealership in Carlow, Ireland), contacted me to let me know he is one of only 15 Nissan dealerships in Ireland who have been approved to sell the new all-electric Nissan Leaf. As such he had a limited number of slots available for a test drive and he wanted to know if I’d like one of them. I jumped at the chance!

The Leaf is a totally electric car relying completely on its 24 kW?h/90 kW lithium ion battery pack for power. The battery pack is rated to deliver 100 miles on a full charge but this can vary from about 62 miles (100 km) to almost 138 miles (222 km) depending on driving style, load, traffic conditions, weather (i.e. wind, atmospheric density) and accessory use.

The car is a five seater with a spacious interior. It is very responsive to drive. My own car is a 2008 Toyota Prius and this is a much nippier car than the Prius. It handles well on the road and because there are 300kg of batteries under the floor, the car sticks to the road on corners!

Charge time varies on the type of charging (normal or fast) and whether the battery is fully depleted or only partially. Using a standard 220/240 volt 30 amp supply the battery can be fully charged in 8 hours. Fast charging using a 440V level 3 charger charges to 80% in around 20 minutes – these are typically the kinds of chargers you will see deployed in places like McDonalds, Tesco’s and motorway caf?’s I assume.

There is a lot of technology built in to the car. It is connected to a global data center which provides support, information and entertainment at all times. The GPS navigation system delivers a constantly updating display of your range as well as showing all the charging stations on your route and it allows you to book a charging station to ensure that it is available when you arrive.

Mobile phone apps will allow remote turning on of aircon and heating as well as setting charging times to coincide with time of use rates from utilities. The advantage of turning on aircon/heating before getting to the car is to have it pre-heated/cooled while still connected to the mains to save on battery life.

It has a spacious boot and there is an option to get a rear spoiler with solar panels to trickle charge the auxiliary 12 volt battery, though, tbh this feels like a bit of a gimmick!

In terms of the main battery, Nissan has announced that it will warranty the battery pack in the Leaf for 8 years or 100,000 miles after which time Leaf batteries will still hold around 70-80% of their rated capacity. I suspect that there will be a significant market for slightly depleted car batteries at that point for home energy storage to better enable load shifting and smart grid applications.

The car I was driving is a pre-production model. Because the production lines are only now being set-up, this one was hand-made and is insured for a replacement value of ?1.2 million! Consequently I drove it very carefully.

Conclusion: The Nissan Leaf is the future of motoring, no doubt. It is fast, affordable and very cheap to run. And that’s not taking into account at all, the environmental advantages of running a zero emissions car! Sure, there are limitations to having a car with a 100 mile range – most of these will be overcome by the roll-out of networks of fast-charging stations. After this test drive, I have no doubt that when it comes time to replace my Prius, my next car will be all-electric.

The Leaf goes on sale in Ireland in February 2011 at a price of ?29,995 (after a ?5,000 govt subsidy), in the UK in March 2011 for ?28,990 and in the US in December for US$32,780.

And finally, if you are interested in going entirely zero-emissions with your motoring, my buddy Ray (mentioned above) has partnered with a solar panel company and they are able to offer a Nissan Leaf and the solar panels to charge it from. Now that’s serious awesomeness!
