 VDA: German car industry is European champion in e-mobility - the only problem is the charging network According to the VDA, Germany's car manufacturers are European champions in e-mobility. The association demands that politicians do their part and accelerate the expansion of the store network. © VW AG VW ID 3. Hildegard Müller, President of the Association of the German Automotive Industry (VDA), sees the German carmaker as market leaders in Europe. Compared to the German Press Agency (dpa), she even used the term “European champion in electromobility”.

Electromobility is key for sustainable traffic solutions on roads, rails and the sky. Learn what e-mobility means for you at Infineon. Devices termed inverters convert the battery’s direct current into alternating current for driving the electric motor. The more efficient conversion is, the longer a car

48V electrical systems have advantages over current 12V systems , providing 4 times the power and providing greater efficiency when powering fans The number of full electric vehicles (EVs) is rapidly growing and, as a result, the charging infrastructure is also expanding, including DC fast charging

The energy and traffic transition go hand in hand - and those who live in their own home with a photovoltaic system can already charge their electric car with environmentally friendly solar power. An experience report.

It's been two years since we moved into our new home. It was already clear to us during the planning phase that we wanted to build as sustainably and energy-efficiently as possible. In addition to an appropriately insulated building envelope and the use of natural materials, this means above all that both heating and domestic water heating are taken over by a heat pump.

  Tested: 2007 Compact Car Comparison Somewhere south of 20 grand, there's a sweet spot of cheap miles and wide smiles. We compare seven of the contenders—Toyota Corolla, Honda Civic, Hyundai Elantra, Mazda 3, VW Rabbit, Nissan Sentra. From the December 2006 issue of Car and Driver.What's not to like about combining frugality with fun? Nissan's all-new-for-2007 Sentra comes standard with a six-speed manual. Let's round up the whole class of compact four-doors, equip them with all-natural U-shift-'em gearboxes, and enjoy driving while we compare choices at the low-budget end of the market.There's action once again in the small-car biz.

Electric cars (EVs) and plug-in hybrid vehicles are relatively new on the market and the fact that they use electricity to propel themselves means a new infrastructure has been put into place, one Level 1 charging happens when you charge an electric vehicle (EV) using the charger included with the car .

Highway transit charging . In certain situations, charging an electric car has to be as fast as for/with Today's electromobility is both safe and efficient. And it's growing fast, right along with the The innovative drive system from Siemens, ELFA is a key component in meeting your complex challenges.

Another aspect is energetic self-sufficiency. With a heat pump and two electric cars , the electricity consumption in our household is correspondingly high. To counter this, we had a photovoltaic system and electricity storage installed during the construction phase. This enables us to achieve an annual degree of self-sufficiency of 81 percent. In other words: We only have to cover 19 percent of our annual energy requirements with electricity from the public grid.

The calculation is quite simple: For every generated kilowatt hour of electricity that we feed into the grid, we receive 10.48 cents (feed-in tariff). For every generated kilowatt hour of electricity that we consume ourselves, we pay around 9 cents (taxes) instead of 30 cents from the network operator. With an annual electricity consumption of 10,000 kWh, of which the photovoltaic system covers 8,100 kWh, this means a saving of 1,700 euros plus feed-in tariff.

Like, now.Bloomberg reported Wednesday that both of the parcel delivery companies are facing a serious delivery van shortage. In other words, both need more vans as soon as possible and its partners have started to either lease vans, or purchase used ones. Brendan Keegan, CEO of Merchants Fleet which provides vehicles to delivery companies, told the publication that any and every van that is for sale isn't off limits. The company needs them now.

A wide variety of electric car charging stations options are available to you -Ensure the operation of the charging pile are stable, and the environment for use of the equipment should be kept as clean, constant temperature and humidity as possible.

Depending on the size of the system, a photovoltaic system pays for itself after 9 to 13 years - with a guarantee period of 25 years.

photovoltaic system: solar power for the electric car

In recent years, both the modules for photovoltaic systems and the power storage have become significantly cheaper. At the same time, however, the feed-in tariff for new systems also fell continuously. This means that a photovoltaic system is economically "lucrative" above all if you use as much electricity as possible yourself and feed in as little as possible - keyword optimization of self-consumption.

On the one hand, you can use an electricity storage device for this - and thus use the electricity generated during the day in the evening and at night. On the other hand, of course, an electric car that can be charged with solar power. Or both in combination.

For example, we need around 4,500 kWh of electricity a year for our two electric cars alone. Another 4,000 kWh for our heat pump. A normal-sized photovoltaic system with 9 kWp delivers around 9,000 kWh annually.

2. The electrical system . Before buying a charging station for electric vehicles it is essential to pay attention to To be truly respectful of the environment, electric vehicles must be recharged with clean energy, that is coming from renewable sources ( photovoltaic , wind or hydroelectric).

The global charging system has different versions. We can. found the recharge by photovoltaic system , the recharge by. with charger and the system efficient for the mobile cars with . In this work, the wireless charger system for the electric . vehicle is exposed and explained.

In this context, smart energy management is crucial. With us, for example, all consumers in the household (heat pump, washing machine, light, etc.) are supplied first. Then the power storage is charged. The “surplus” then ends up in our electric cars. This results in a charging power between 2 kW and 11 kW, depending on the season. We don't have to worry about anything, as the energy manager of the photovoltaic system intelligently communicates with the consumers in the household, the power storage and the Wallbox .

Help shape the transport and energy turnaround

I am often asked whether investing in a photovoltaic system is really worthwhile. For this reason, I have primarily addressed the economic aspects in the previous paragraphs. Buying or building a house is already associated with high costs, so arguments such as sustainability and self-sufficiency often take a back seat. Ultimately, however, a photovoltaic system is actually the only component of a house that pays for itself - and even generates a return over 25 years.

In interaction with one (or two) electric cars, there is another factor: you drive almost for free. If you charge a BMW i3 with solar power, the cost per 100 kilometers is around 1.40 euros. With an EQC or E-Tron it is 2.30 euros.

The initial investment of EUR 20,000 for a photovoltaic system (10 kWp) including storage (8 kWh) pays for itself very quickly in this way - and you are still doing something good for the environment.

electric cars stand for sustainability and not only protect the environment but also the owner's wallet. The problem: Drivers of e-cars often lack a domestic power connection to charge their own vehicle.
