Volkswagen AG has started its delivery of a second test batch of Golf blue-e-motion electric cars to clients in Germany. Fifty-three out of the 80 units being tested in the fleet will be delivered in Berlin while the rest will be sent to Wolfsburg and Hannover.
The cars will be distributed to private motorists, public bodies and businesses, although most of the vehicles in Berlin will be tested by corporate customers, as VW views this group as the largest market for EVs in the future.
Among the companies participating in the tests are Deutsche Telekom AG, Continental AG, Coca Cola AG and Deutsche Bahn AG.
'The Golf blue-e-motion fleet is an important milestone within the company's development plans for electric mobility Rudolf Krebs, chief for electric traction of VW group, stated. He added that it allows the company to secure all aspects regarding technical detail, user requirements and everyday drive-ability ahead of series production.
According to VW, those testing the electric cars can monitor the vehicle via a special iPhone application and get advice and support from a specially established call center and website.
The Golf will be the second of three electric vehicles to start sales in 2013, before the Jetta blue-e-motion and after the Up blue-e-motion. They will be joined in the same year by an electric variant of the Lavida for the vehicle market in China, the company revealed.
German carmaker Volkswagen is ushering itself further into the new era electric mobility with the unveiling of the new Volkswagen Golf blue-e-motion Concept. An electrically powered version of the VW Golf, the blue-e-motion concept comes in five-door and five-seat versions. Serving as the core of the new Volkswagen Golf blue-e-motion Concept is a zero-emission electric motor in the front engine compartment that could provide up to 85 kW (115 PS) of max output, 50 kW (69 PS) of continuous output and 270 Newton-meters of torque available immediately.
This electric motor is powered by a lithium-ion battery with an energy capacity of 26.5 kWh, allowing the front-wheel drive VW Golf blue-e-motion to travel up to 150 km, with a range that depends on driving style and factors such as use of the air conditioning and heating system. VW will disclose the final driving range data of the production version of the Golf blue e-motion at the electric vehicle’s production launch. It is expected that the final range will be significantly better than the current numbers because of future improvements in battery technology.
Furthermore, a range of 150 km should be more than enough to meet the travel needs of commuters. In Germany, six of 10 working people travel by car, according to data from the German Federal Statistical Office. On average, 45.8 percent of commuters in Germany drive less than 10 km (for a one-way commute), while 28.1 percent of commuters travel between 10 km and 25 km. Around 16.2 percent of German commuters drive over 25 km every day. Moreover, the Volkswagen Golf blue-e-motion Concept is capable of achieving driving ranges typically covered by a number of service providers. However, the maximum range of electric cars – more obviously than on conventional vehicles – drops drastically when its max power is used more frequently.
To address this on the VW Golf blue-e-motion Concept, the carmaker made sure it is aerodynamic enough (Cd value: 0.295) and has ample power reserves to allow it to move as swift as possible while using up less. In addition, the very aerodynamic Volkswagen Golf blue-e-motion (Cd value: 0.295) provides ample power reserves to move the car swiftly while consuming less energy.
In fact, the new VW Golf blue-e-motion has the capability to coast or "sail." A vehicle sails when the driver adopts an anticipatory style of driving by releasing the gas pedal, or in the case of the new Golf blue-e-motion the electric pedal. As soon the electric pedal is released, the motor is controlled to the zero-torque curve to allow the new VW Golf blue-e-motion to coast with the least possible drag.
When sailing, the new blue-e-motion Concept could recover kinetically generated energy by battery regeneration, resulting to an EV that could quickly perform maneuvers like passing. In fact, the new VW Golf blue-e-motion Concept could accelerate from zero to 100 km/h in just 11.8 seconds and reach a top speed of 135 km/h.
On the other hand, the battery pack for the new VW Golf blue-e-motion Concept is made up of 30 battery modules -- consisting of 180 lithium-ion cells with energy capacity of 26.5 kWh -- installed in spaces adapted to the architecture of the VW Golf. Weighing a total of 315 kilograms, these battery modules could be found in the floor of the EV’s boot space, in the center tunnel of the underbody between the front seats, and under the rear bench seat. These modules are kept under operational temperature by a separate air cooling system in the battery compartment.
To make the new VW Golf blue-e-motion Concept more suited to electric driving, it has been fitted with several instruments. For instance, the classic tachometer has been replaced by the kW gauge, which shows the amount of energy demanded by the "electric pedal" at any given moment. This should practically urge drivers to keep the gauge’s kW reading as low as possible, intuitively. The kW instrument also includes a range indicator. Other instruments include a speedometer that integrates a smaller gauge that shows the current status of the battery’s charge as well as a multifunction display that includes a gauge that shows the regeneration intensity.
Drivers are given the power to pre-set the braking energy recovery strategy in four stages (D to D3) through the automatic gearshift lever or via gearshift paddles mounted on the steering wheel. In the D stage, the new VW Golf blue-e-motion Concept sails as soon as the electric pedal is depressed. When sailing, the new VW Golf blue-e-motion cruises with very low drag and is "slowed" only by the air resistance and rolling resistance of the tires. In the D3 stage -- or B for braking – the new VW Golf blue-e-motion Concept recovers the maximum amount of kinetic energy and sends them back the battery. Furthermore, the multifunction display could show the amount of electrical energy consumed by the automatic climate control unit and its blower.
