DUAL POWER SYSTEM FOR A MILD HYBRID VEHICLE, FOR CHARGING A BATTERY WITH ELECTRIC ENERGY OF LOW VOLTAGE WITHOUT USING AN INVERTER AND A CONVERTER FOR HYBRID

摘要

PURPOSE: A dual power system for a mild hybrid vehicle is provided to supply the electric energy of high voltage by boosting the electric energy by using an inexpensive analogue multi switch and a relay switch.;CONSTITUTION: A dual power system for a mild hybrid vehicle is composed of batteries(31,32,33), a relay switch(R1,R2), a multi switch(90), a switch driving part(80), and a controller. The batteries are serially connected to the driving motor to supply the electricity to the driving motor. The relay switch serially connect/release the batteries according to the driving condition of the contact point. The multi switch connects the batteries to a generator and electronic components through a circuit. The controller connects the batteries to the electronic components in parallel or serial by controlling the switch driving unit.;COPYRIGHT KIPO 2010
