<p><em>A single series resonant converter has been designed to balance the voltage level of a storage battery for electric vehicles. The proposed design has been simulated and verified by using two 100F supercapacitors instate of the conventional rechargeable battery. A voltage monitoring circuit detects the voltage condition of the individual capacitor and sends the voltage status to the control circuit for action. A technique has been developed to control a set of switches to transfer the current between the capacitor to balance the voltage level. The MATLAB simulated result shows the balancing circuit decreases the voltage difference between the two supercapacitors from 200 mV to 0V in 140 seconds, which is less than the existing methods. This fast voltage balancing technique can be used in the battery management system or electric vehicles for long lasting the battery life.</em></p><p><em> </em></p><strong><em>Keywords</em></strong><em>: Voltage balancing; electric vehicles; supercapacitor; battery; series resonant converter</em>

High Speeds

Fuel Cell Vehicles (FCV’s) are gaining more attention in the present scenario as it overcomes the disadvantages of internal combustion engine vehicles and electric vehicles. FC technology for automotive applications is an attractive prospect for automotive manufacturers and consumers. But one of the main barriers for the adoption of FCV’s is the increased cost of fuel cell stack. Also the FC stack voltage reduction while accelerating is another problem as power reduces at high speeds with increase in current. This paper presents a 10 hp PMSM drive with reduced size and cost with 8 KW fuel cell stack for FCV applications fed from EF2 resonant converter which improves the dynamic performance and system reliability. The simulation result which validates the enhanced performance is also produced.
