The invention provides electric heating glass and a vehicle window assembly. The electric heating glass comprises laminated glass and a heating element, the laminated glass is provided with a sensor visual field area and a windscreen wiper staying area, and the heating element is arranged in the sensor visual field area and/or the windscreen wiper staying area. When a working voltage of 40V-52V is applied to the heating element, the heating element has heating power density in a sensor view area and/or a windscreen wiper stay area, and the heating power density is 450W/m < 2 >-1200W/m < 2 >. According to the system, rapid demisting, defrosting, snow removing and ice removing can be achieved, the heating precision and the energy utilization rate can be improved, the heating temperature can be controlled within a proper range by limiting the power density, and the energy loss of the whole vehicle can be reduced; and moreover, the sensor view field area and the windscreen wiper stay area can be independently heated or simultaneously heated, the heating requirements of different scenes are met, and the heating effect of the electric heating glass is improved.

    本申请提供了电加热玻璃及车窗总成。电加热玻璃包括夹层玻璃、及加热元件,夹层玻璃具有传感器视野区以及雨刮停留区,加热元件设于传感器视野区和/或雨刮停留区;所述加热元件被施加40V~52V的工作电压时,加热元件在传感器视野区和/或雨刮停留区具有加热功率密度,加热功率密度为450W/m2~1200W/m2。本申请既能够实现快速除雾除霜除雪除冰,又能够提高加热的精准度以及能源利用率,还可以通过限制功率密度,将加热温度控制在合适的范围内,有利于降低整车的能源损失;并且,本申请还能够实现传感器视野区和雨刮停留区各自独立加热或同时加热,满足不同场景的加热需求,提高电加热玻璃的加热效果。
