IMPROVEMENT AND FUTURE WORKS OF

PROJECT

Efficiency will be calculated and solved theproblems

Rectifier part of circuit can be created again with

mosfets Filter circuit will be improved to pi type If it

needs

BMS(Battery management system) adding

Power factor correction and harmonic reductionare studied

Charging will be observed and controlled by PCinterface 13



FUTURE OF PROJECT IN TURKEY

ÖTV is % 37

4000 Electric vehicles are on road until end of 2012

Charge stations in shopping centers The cost of one station installation is 10.000TL

Fuel Oil 4 TL/1 liter
