96 recycled MEB cell modules, Volkswagen Sachsen’s fast-charging car park and large power bank
- ID.5 power consumption plus 14.6 kilowatt hours per 100 km (NEDC), #CO2 emissions plus 0 grams per km, efficiency level A+++
- Pilot project for reuse of used batteries from ID.3  and identification.4 
- Goal: To promote the development of #fastcharging infrastructure in residential areas
- Karen Kutzner, Managing Director Finance and Control at Volkswagen Sachsen: “A practical, cost-effective and beneficial program to give unused cell modules a second life.”
Volkswagen today put the first fast charging park in Saxony into operation at the Zwickau car plant, which draws most of its energy from so-called #Power #Storage #Containers (PSC). #PSC is a type of large #power storage and consists of 96 cell modules with a total capacity of 570 kilowatt hours. Advantage: Even if the existing connected load is small, #fastcharging #infrastructure can be configured almost anywhere. Possible locations are, for example, residential areas. In addition, the solution is sustainable: All the cell modules installed in the PSC were on the batteries of the original ID vehicles. 3 designs  and identification.4  installed and now get a second life. With the pilot project, Volkswagen Sachsen is also showing its technological expertise outside the production of its 6 electric vehicles. With AW Automotive and Automotive Research, 2 other Central German companies were involved in the realization.
Karen Kutzner, Managing Director Finance and Control at Volkswagen Sachsen: »The continued use of batteries is an important topic for the future which is closely linked to the development of #electromobility. With the Energy Storage Facility, Volkswagen Sachsen demonstrates a practical, cost-effective and beneficial application for giving unused cell modules a second life. This automotive energy storage can be used wherever the connected load is very small but there is a need for high performance charging infrastructure. The critical development of fast charging infrastructure can be given a new impetus by such innovative ideas.”
As a large battery storage device, the PSC offers a cost-effective alternative to the substation. It enables the delivery of large amounts of energy in a short period of time without placing a high average load on the power grid. Another advantage: by storing energy for a while, the high base costs that arise in standby mode, even if there are no charging vehicles, are avoided. Therefore, the #powerbank for cars can create an HPC infrastructure in the future, for example in residential areas where, due to the low network voltage, a high level of AC charging with 11 kilowatts has been possible so far. In the case of fast-charging parks and high-power chargers (HPC), #transformer stations are usually installed with a connection to the medium-voltage power network, which operates 24 hours a day and requires a large initial investment. This differs from the average pay time of a few hours per day.
The charging park in Zwickauer Tor West has four charging stations, each with an output of 150 kW, which can be divided up to 75 kW. Up to eight vehicles can be charged in parallel. Electricity is produced, among other things, from a nearby photovoltaic system. Since Volkswagen Sachsen has been using green electricity since 2017, all vehicles are powered by 100 percent renewable energy. By the end of the year, three fast charging parks will be operating on the factory premises.
#Audi with the first use in the country
With PSC, Volkswagen Sachsen is using a solution that Audi is already using successfully for the first time in urban areas in Nuremberg at the Audi charging station. The container parts include lithium-ion batteries that come from dismantled Audi test cars and serve as direct current backup storage.
1.) ID.3, power consumption in kilowatt hours per 100 kilometers (NEDC) 13.7 to 12.9 (inclusive), CO2 emissions 0 grams per kilometer, efficiency class A+++
2. ID.4 – combined power consumption in kilowatt hours per 100 kilometers (NEDC) 14.8, combined CO2 emissions 0 grams per kilometer, efficiency class A+++
Specific consumption and emission values were determined according to legally established measurement methods. Since 1 September 2017, some new cars have already been approved according to the Worldwide Integrated Light Vehicle Test Procedure (WLTP), the most realistic method for measuring fuel consumption and CO2 emissions. Since September 1, 2018, WLTP has replaced the new European driving cycle (NEDC). Due to the actual testing conditions, fuel consumption and CO2 emission levels measured according to WLTP are often higher than those measured according to NEDC. More information on the differences between WLTP and NEDC here …
NEDC values are currently still mandatory to submit. In the case of new vehicles that have been type-approved according to WLTP, the NEDC values are based on the WLTP values. Additional measurements of WLTP values can be provided on an optional basis until their mandatory use. Insofar as NEDC values are given as a range, they do not refer to a single, individual vehicle and are not part of an offer. They are used only for comparison purposes between different types of vehicles. Additional equipment and accessories (accessories, tire design, etc.) can change relevant vehicle parameters such as weight, roll resistance and aerodynamics and, together with weather and traffic conditions as well as individual driving habits vehicle, can affect fuel consumption, power consumption, CO2 emissions and vehicle mileage.
Note according to Directive 1999/94/EC in the current version
