EV-Simulator and Oscilloscope

Visualisation current setting

The communication protocol carries information on the maximum current the car is allowed to draw. This ensures (for example) that high capacity EVs can be charged at low capacity charging points without overloading the grid connectopm (blowing the fuses). This enables also even more dynamic charging based on the availability of (renewable) energy. This is called smart charging.

Electric cars connected to the grid with smart charging create a symbiosis with the power grid — they support each other. Without smart charging, this connection wouldn't exist and EVs could become a burden on the grid.

Using an oscilloscope or multimeter the communication signal can be visualized.

Two switches allow to set the 'EV Ready' and 'EV Charge' states simulating respectively the connection of the EV and the request from the EV to charge. The CP signal, generated by the charge point, can be visualised on a scope or multi-meter by connecting it to the BNC connector on the EV-Simulator. The difference between EV Ready state and EV Charge state is observed by a lower voltage level of EV Charge.

When no EV is connected, the positive signal has an amplitude of 12 Volt. In state EV Ready, this is lowered to 9 volts. The EV Charge state can be recognized by a 6 volt amplitude.
