Sehr interessantes Video über die Alterung einer Batterie beim VW e-Golf.
In one of the latest episodes, Bjørn Nyland had an opportunity to test the first generation of the e-Golf (24 kWh) – about 6.5 years old (since September 2016) with rather low mileage of 47,861 km (roughly 30,000 miles). The fully charged car was been range tested at a constant speed of about 90 km/h (56 mph). According to the video, the fully charged e-Golf covered some 120 km (75 miles) and still had some more range left – an estimated 6 km (4 miles) at roughly 5% state-of-charge (SOC). It means that its total range in the given conditions should be about 126 km (78 miles). However, it’s important to note that at a low SOC, the car enforces an Eco mode (it happened at roughly 20% SOC). The car’s display indicates an energy consumption of 148 Wh/km (238 Wh/mile), which means that the usable battery capacity can be estimated at about 18.7 kWh. Bjørn Nyland assumes that the usable capacity of the new car was about 20 kWh out of 24 kWh, and the battery capacity degradation is around 6.5%.
