Q)Discuss two new trends in battery system field. Solution: A battery is a pack of one or more cells, each of which has a positive electrode (the cathode), a negative electrode (the anode), a separator and an electrolyte. Using different chemicals and materials for these affects the properties of the battery – how…

Series Architecture Here motor is only element that is directly connected to the transmission system There is no direct connection of ICE engine with transmission system Here there is generator along with the ICE engine for producing electric energy from ICE engine. Motor get electrical energy either from battery or ICE…

Q1) A) Speed control of a DC motor using BJT H-bridge The figure below shows the model of speed control of dc motor using H-bridge Working The model contain 4 IGBT Q1,Q2,Q3 and Q4 which act controlled switch and 4 diodes D1,D2,D3 and D4. Field winding is excited with a 300V DC source. Controllable H bridge is connected…

Q1)  To find types of power converter circuits are employed in electric and hybrid electric vehicle. solution: Power electronics converters play a crucial role in in electric and hybrid electric vehicle. There different power converter circuits used in  electric and hybrid electric vehicles. They are given below. AC to…

Q1)   To find difference between mapped and dynamic model of engine, motor and generator. In mapped model, we use lookup table for analysis of performance. The simulation time required for this is less as compared to dynamic model. That is, it is faster. The below figure shows the mapped model of  EV motor/generator.…

Q1)  Aim:        To find whether EV_defaults_in Vehicle can travel 45 km with FTP drive cycle if cargo mass is 500 kg with all other default conditions. The EV Default vehicle is a pure EV where it’s completely driven by battery as power source. The figure below shows Advisor tool…
