Mains Charging: 2nd contractor switches in 10 ms: Earth leakage trips Residual Circuit Breaker limit in on-board charger: Electric Vehicle 006:

 

Soft Start and Inrush Limited Battery Charging

The First Contractor

Connects the mains to the single phase/three phase transformer. With anti-surge supplied by two

resistors in parallel on the Live and Neutral power lines. Mounted across the second contractor

that switches in after 10ms. With peak energy at 14.5kW. The peak energy defines the power

selection of the resistors.

 

In-rush Power Protection

Supplied by the Residual Circuit Current Breaker. It trips when Earth leakage exceeds the set figure.

Allows time for the Transformer impedance to settle when using the on-board charger.

Physical Size

Both the power source and on-board charger. Being limited by technology. It is moving fast and in

3 to 5 years will be the size of a paperback book.
