They can be charged more quickly by using an electric charging point, Pradelli said.

普拉德利说，通过使用充电点，它们可以更快地充电。

There are to be financial incentives for car manufacturers, and more charging points are to be installed in streets.

政府将为汽车制造商提供财政激励，并在街道上安装更多的充电站。

They set new standards for ventilation, energy efficiency and heating , and state that new residential buildings must have charging points for electric vehicles.

他们为通风、能效和供暖设定了新标准，并规定新的住宅建筑必须有电动汽车充电点。

Oslo is a city that's subsidizing electric vehicles and charging points.

When an EV is plugged into a standard charging point, its systems convert AC into direct current (DC), which is what a battery needs to store electricity.

当电动汽车插入标准充电点时，其系统将交流电转换为电池存储电力所需要的直流电(DC)。

America's Department of Transportation approved plans to develop infrastructure for electric vehicles in all 50 states, and build a network of charging points covering 75,000 miles (120,700km) of highway across the country.

美国交通部批准了在全国50个州发展电动汽车基础设施的计划，并在全国修建覆盖75000英里(120,700公里)高速公路的充电站网络。

We can substitute in the equation for the electric field  which surrounds a point charge and the equation for the surface area of a sphere into the electric  flux equation.

我们可以将点电荷周围的电场方程和球体表面积方程代入电通量方程。

If we zoom out: looking at this pair of particles from far away, you can see that it looks like the field lines for a single positive point charge.

如果我们从远处看这对粒子，那么 它们显示为单个正点电荷场线。
