High-voltage charging is
a strategy for the future
Just like the engine power of an internal combustion engine car, the main parameter of an electric car is the battery capacity. The range and charging time depend on this indicator. And these are the main questions for every driver. And on a more global scale, they determine how quickly electric transport will become a mass phenomenon.
A little bit of theoretical physics (this is necessary to understand the essence of the problem and the directions for its solution).
Power is a physical quantity that directly depends on the current and voltage.
So, it's simple: we increase the current and/or voltage, the power increases.
In theory, this is true. But in practice, there are side effects. Increasing the current requires the use of powerful and heavy cables with thick insulation. Their weight and dimensions become a real operational problem. In addition, the high-voltage cable emits a large amount of heat, which can lead to overheating of the battery and cable. These factors negate the feasibility of this direction of solving the problem.
The option of increasing the operating voltage seems more technically sound. Most electric cars of previous generations have a voltage of 400 V. If you double this figure (bring it to 800 V), you can approximately 2 times increase the power or 2 times reduce the dimensions of the battery. Currently, this is the path that leading manufacturers of electric vehicles are taking..
High-voltage batteries are already being developed and installed on premium models. It is expected that in the next 5 years, 800-volt architecture will become standard for most electric vehicles.
EVC ND FAST series charging stations are designed for voltages up to 1000 V. This means that EVC ND FAST can effectively service electric vehicles of both current and future generations..
