"飞行汽车的动力系统需要更为强劲的动力电池。"长三角研究院新能源应用技术研究中心研究员梁筱磊介绍，相比较而言，由于飞行汽车需要更高 能量密度的电池支撑，因此，新能源汽车的电动系统无论在能力上还是功率密度上都难以满足飞行汽车的需求，并制约着飞行汽车的试飞行时间在10-30 分钟左右。载荷小、航程短等问题阻碍着飞行汽车难以投入商业化应用，也难以与用户期望的数小时飞行续航的想象相差甚远。同时，快速充电技术也 是一大挑战。从实用角度看，要在飞行汽车高剩余电量时实现快速充电不仅难度大，还得保证充电安全和电池寿命不能受损，这些都对充电技术提出了 更高的要求。而这些，也是眼下亟待突破的技术瓶颈之一。 同时，与陆地行驶的汽车拥有较为成熟的系统不同，飞行控制技术是飞行汽车安全和稳定飞行的重要基石。同时，飞行汽车不仅要适合风和日丽的 天空飞行，还要适应高低温变化，以及在风雨、气流、空中时常变化的大风等复杂的气象环境下稳定飞行，这些都需要精确控制姿态、高度、速度等。 由于飞行汽车相比传统飞机体积小、重量轻，在低空飞行受气流影响更大，其飞控系统必须更加灵敏、精准、可靠、稳定。而实现自主导航与及时避 障，也是飞行汽车面临的一大技术难题 ...
