PHEV Power Traction System for Light Boats

Electrification of Boat Power Traction System – PHEV
1)For light boats, the electrification of power traction is the trend with a lot of advantages :  increase efficiency of the power traction system, decrease of the exhaust gas emission, increase the power performance, and low noise;EV and PHEV power traction system have bright future for application!
2)PHEV power traction technology can let the boat to be traveled with pure EV mode with in the battery range limit, and be operated also with DIESEL engine for long range traveling ; While the boat can be plugged in for electricity charging during parking time;
3)With PHEV technology, two modes existed i.e. BEV and PHEV which can greatly increase the boat operation safety for long range;
4)The PHEV boat can be charged with DC quick charger, and also with A/C charger of 220V or 380V;
5)Compared with the vehicle, the boat can easily digest the high cost the electrical power system such as battery and motors;
6)The PHEV boat  can also increase the boat drivability performance;

PHEV – Power Traction Unit (dual motors)

Functions: of power traction unit :
1) Pure EV traction (2 gear ratios);
2) Range extender : Diesel Engine  generates  electricity  for battery and  motor;
3) Diesel engine direct traction( high speed);
