Diesel bus emissions - who knows the bad smell?

Écrit par akrause le . Publié dans Public Transport.

For an environmentally friendly future in public transport – setting a green example!
Do you know this too? You’re riding your bike to work, school or university and suddenly you notice by the smell: a diesel bus stops next to you.

Noise and odor pollution are the order of the day. Many countries are setting a good example: China, for example, has the largest share of all electric buses worldwide running thanks to subsidies, and Salzburg is relying on the zero-emission OBUS, short for “Oberleitungsbus”. Germany, for example, can point to the VHH in Hamburg or the LVB in Leipzig. In the meantime, every transport company should decide in the long term to convert to electric buses, because this process takes time. So: If you want low-congestion as well as climate-neutral local transport by 2030, you should get started now!

What are the costs of an e-bus? 
The purchase price for an e-bus is higher than for a conventional diesel bus, but there are still many advantages. The German Environment Ministry’s subsidy program covers up to 80 percent of the additional costs incurred compared to a diesel bus, and also up to 40 percent of the costs required for startup, such as driver training. As with electric cars, the higher cost of the investment is recouped through lower expenses in operation as well as for maintenance.

Why are e-buses so efficient?
In “stop and go” operation of public transport buses, both energy and brakes are conserved. This works thanks to instantaneous full torque, which an internal combustion engine cannot provide in this way. In addition, a part of the energy is returned to the batteries during braking. Among experts, this is called “recuperation”.

How do driving and charging work on an e-bus?
E-buses drive like normal diesel buses with automatic transmission. They now have a range of several hundred kilometers – so they are a real option for public transport.

Either the driver stops at a charging station and connects the bus to the charging cable or it charges wirelessly, the latter being increasingly the case. Thus, the driver does not even have to get off the bus – very convenient, in other words. There are also various concepts for flexible use: overnight charging in the depot, intermediate charging at stops, or mixed forms. This is also where the difference to the diesel bus comes in: refueling must take place more often and charging must be organized intelligently.

CarMedialab’s software is ready to do just that. MOBILEcharge enables intelligent charging. 

Let’s become more MOBILE together!

Charge and save: If not now, when?

Why electric driving is coming to the fore in light of rising gasoline prices
In fact, electric cars are increasingly performing better when you add up all the costs of owning a car. Although they usually have higher initial costs, they are significantly more economical, for example in terms of maintenance: Savings of up to 35 percent can be achieved here. In the long term, therefore, the price difference compared to diesel or gasoline vehicles can be compensated for in the acquisition costs. Nevertheless, there are more and more cheaper electric cars on the market with a subsidy of up to 9,000 euros. In addition to the purchase price, there are other factors that come into play.

Taxes
The benefits don’t end with the purchase. Up to ten years of exemption from vehicle tax, depending on the time of registration, can be granted. As a company car with private use, only 0.25 percent of the gross list price even has to be taxed.

Charging costs
Not only the billing model is decisive for pricing, but also how high the charging power in kW is at the charging point, how fast you can charge and which car you drive. The efficiency of the energy is very high.

What is unbeatable, however, is that vehicles can charge for free at some supermarkets, for example, while gasoline or diesel are not available for free. Otherwise, of course, the tariff in one’s own household determines further costs, while prices at public charging stations vary widely.

Maintenance
Due to the fact that electrically powered vehicles contain fewer parts that are susceptible to wear, maintenance is a big plus point. Technical inspections are also less expensive, since the exhaust emission test is no longer required.

So what’s stopping you? CarMedialab supports charging station manufacturers with software and manages charging processes to make electric driving possible.

Let's change our mobility behaviour!

Écrit par admin le . Publié dans Public Transport.

As the world is changing and the population is growing continuously, the carbon footprint we leave behind grows bigger and bigger as well.

Therefore we need to rethink how to get from A to B with the least possible pollution impact. So how do we do that? The answer lies in sustainability. Using green electricity for fuel to go from one place to another. At the moment, everyone wants to use their own transport vehicle. They fill up the streets since only a few people occupy each vehicle, and this creates a lot of traffic, which then creates even more pollution, as fuel driven cars, busses and trucks let out a lot of carbon dioxide, when waiting at the traffic light.

Now we all need to reconsider the need for transportation and think about the option of going by public transportation instead. Most of the time we’re actually going the same way and we always hate sitting in traffic and wasting time. Time that could be better spend with family and friends.

So what if we changed our mobility behaviour and started using the public transportation? 
Many busses use fossil fuels. But what if we could boast about the public transportation in a whole city purely driven by electricity? The biggest issue with electromobility is the access to charging stations and the distance to travel on a single charging. But we need to dream big and have big goals for the future we want to go in and redesign towns. We need to make sure that the future generations can live and breathe clean air. This is what the transport system should enable.

Improved accessibility and mobility for all
In relation to the BBC series about redefining public transportation, that will be created in collaboration with UITP (The International Association of Public Transport) Simon Shelley, the Vice President of Programme Partnerships for BBC StoryWorks says:

“As we look towards the future of public transport, improved accessibility and mobility for all will play a critical role in the quality of life for both passengers and transport workers – the people at the heart of urban mobility. The story of public transport is that of a passionate and innovative community….”  CarMedialab supports this vision and offers software systems that give people access to the new mobility. Let’s get it on and use public transport!

Hallå där ute!

MOBILEcharge now also speaks Swedish. With our charging management, we contribute our know-how for reliable operation of electric buses. Initially, 12 e-buses will be charged at the brand-new depot of Gamla Uppsala Buss AB (GUB). In addition to the planning system, we will also integrate the network operator’s transformer station and, of course, ensure automated preconditioning of the vehicles. In keeping with the motto: “Are you still charging or are you already driving?”

Electricity vs. Hydrogen

Écrit par admin le . Publié dans Public Transport.

Why electricity is simpler to use than hydrogen as propellant in cars
To get a non-emission fueled car moving, you need energy. This energy we can harness from the sun or wind and store in batteries, which we then can use to propel our cars. There are many ways to do this, but why not choose the simpler way, with fewer steps from energy source to consumer? 

In comparison: Electricity vs. Hydrogen as a renewable energy source for cars

From water it comes, to water it shall again become
Using Hydrogen to fuel cars is clever. You can extract the Hydrogen form water, and there will only be water-emissions from the car. This is great and green. However, the procedure to procure the Hydrogen and make it fit for cars to drive on is somewhat elaborate.

You use the energy from the sun to make heat, which you will then use to split the Hydrogen from water. Then you need someplace big to store the Hydrogen until you can transport it by truck to the charging points, where it will have to be stored again. In the car, the Hydrogen will have to be stored yet again in the tanks and be used to generate electricity to propel the car. This process sums up to at least five steps from the energy source to the end consumer.

But why go through all these steps to make an electric car run, when you can use only two steps and get the same result?

From sun to power
With an all-electric car, you just plug it in the charging stand, and the battery will be charged almost directly from the sun. By using electricity to power your car, you can benefit from the already present, and rapidly evolving, infrastructure of harnessing power from the sun and wind. These energy sources are never-ending and therefore sustainable. And what is more important, the energy that they procure does not have to be stored at length to be of use. It is transported directly into the exciting power grid, from where it is ready for the taking.

By omitting a lot of steps in the process of power to consumers, it will only become more affordable to drive on the wind – so to speak. Electricity is the way to go for cars and busses, however, airplanes, ships, and heavy-duty trucks among others are not yet suitable for batteries. For that kind of vehicle, Hydrogen might be the way forward if we are to make a greener and more sustainable future of transportation.

OCPP compliance for EV charging stations

Écrit par admin le . Publié dans Public Transport.

By 2030, major countries like Germany and Great Britain will have set sales target for how many electric vehicles (EV) are sold and even limiting the number of internal combustion engine (ICE) vehicles sold. To reach these targets, governments are incentivizing the public to purchase electric cars by providing subsidies such as tax credits to consumers.

The major concern of drivers, who were surveyed about their concerns with EVs, is that there is a limited number of available public charging stations accessible on their route of travel. Nobody wants to be stranded in the middle of nowhere, leaving them with no other option than being towed away. The distance between EV charging stations are still far apart, and the average range of EVs are still less than that of ICE vehicles. Thus, the electrification of the roadway infrastructure affects the decision of choosing between an EV and ICE vehicle directly.

Overcoming this issue will be a matter of installing more EV charging stations. Governments are encouraging companies to install charging stations on site for their employees to charge their cars while at work. They subsidize the purchase so the cost is as low as possible for the new buyer of an electric car.

This potential increase in EV sales will motivate more charging station manufacturers to enter the market. So how do you keep your position in the market and how do you make sure that you’re not being overtaken by a newcomer?

Compliance is key
When EV charging stations become more ubiquitous, the main challenge will be to avoid too many overlapping standards. Different types of charge management systems will limit the number of electric vehicles that can be served by each supplier. This will make the infrastructure even more complex as different types of charging points need to be setup.

If the charge management system are all run on OCPP-compliant software, Smart charging according to the ISO 15 118 standard standard will provide much more flexibility, thus different charging stations can be setup in different locations giving the driver a sense of security, since they will always be able to charge their vehicle.

Therefore, it’s important as a manufacturer to make sure that their charge management system as well as the charging points are OCPP compliant. That way we make smart charging accessible to everyone and we can help governments reach their targets even earlier than 2030.

Let’s do this!
