Electric Vehicles (Battery Electric Vehicles or BEV)
The electric vehicles consist of the e-Up! and the e-Golf. They offer sustainable mobility suitable for reliable daily use and are still fun to drive. They have an electric motor, and no combustion engine, operating through a High Voltage battery with charging via either; a normal 3-pin mains plug, a wall-box charger or the national public charging infrastructure offering both regular and rapid charging through universal connections. The high-voltage batteries are currently of the lithium-ion type. On a full electric energy charge, our cars can travel up to 118 miles between charges.
To charge, an e-vehicle is plugged in either through a charging point, a wall box, or an ordinary mains socket. To charge with a charging cable with a standard mains socket entails charging with an alternating current and can take up to around 13 hours. A wall box can be installed in your home, which reduces charging time to a maximum of 8 hours (These times represent the e-Golf, times may be different for other models).
The fastest option is to charge with direct current from a public charging station using Volkswagens Combined Charging System (CCS), which takes 30 minutes to reach 80% battery (Direct Current or DC charging). However there is a limitation here, as you cannot charge on direct current more than twice consecutively or the high voltage battery could be damaged.
The Lithium-ion high-voltage battery
E-vehicles and the Golf GTE have a 12V support battery, and are also fitted with a lithium-ion high-voltage battery. Lithium-ion high-voltage batteries are made up of several components. The robust exterior housing of the battery contains numerous modules, which are ordered differently inside the battery according to model or space. Each module consists of an array of interconnected battery cells. Electrical energy is stored in the battery cells developed especially for electric and hybrid vehicles. These cells contain a large electrical power supply and a high energy capacity. Energy is taken from the battery during driving and is made available to the electric motor. The electric motor recuperates during braking; this means that the battery is recharged using braking energy. During this entire process, a number of integrated safety systems and sensors are monitoring the cells, in particular their voltage and temperature.
