由于私人乘用汽车每天平均行驶时间不到2小时，每辆电动汽车每天可提供超过22小时的电网服务。所提出的随机模型，它的基础上超过167,000个数据点的流动性调查，模拟私人客运汽车的驾驶行为。本文使用随机模型生成的配置文件估计电动汽车用于电网平衡服务的可用性。三个基本的（“零智能”）充电策略被应用。总之，超过90%的车辆在任何给定的时间点停放。其中，超过25%的人在任何时候都停在家里。此外，模拟结果表明，迫切需要智能充电策略，以避免在晚上的额外高峰负荷，并使电动汽车的服务潜力提供给电网。
Since private passenger cars drive on average less than 2 hours per day, each electric vehicle could potentially provide capacities for grid services during more than 22 hours per day. The presented stochastic model, which bases on more than 167,000 data points from a mobility survey, simulates the driving behavior of private passenger cars. The article estimates the availability of electric vehicles for grid balancing services using the generated profiles from a stochastic model. Three basic ("zero-intelligence") charging strategies were applied.In conclusion, more than 90% of all vehicles are parked at any given point in time. Thereof, more than 25% are parked at home at any given time. Moreover, the simulation results show the urgent need for intelligent charging strategies in order to avoid additional peak loads during the evening hours and to make the service potential of electric vehicles available to the grid.
