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.
