1. Battery Swapping  Picture this, you are in your brand new swanky EV and cruising down the highway when suddenly, you get an alert saying that your battery capacity is rapidly reaching zero. You search for a plug-in charging station and thankfully, you find one just within the acceptable range of the remaining…

Level 1 EV charging The rate of EV charging is 120 volts in Level 1. Most electric vehicles come with a cord and a control box attached to them for Level 1 charging. One can plug in the cord to a three-pin wall socket to begin charging. It takes about 8 to 12 hours to charge from 0 to 100 per cent at Level 1, depending…

The use of inverters can increase or decrease the power or torque of the motor by adjusting the amplitude of the signal.  It plays a significant role in capturing energy from regenerative braking and feeding it back to the battery. The key component is that it has a direct impact on on-road performance, driving range,…

Before that, we will know about what is Electric RICKHAEW, how it's works and the benefits…

An Electric Vehicle (EV) is a vehicle that uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with a battery, solar panels, fuel cells or an electric generator to convert fuel…

STUDY 1:  Weight of Various Types of Aircrafts An aircraft's gross weight will decrease during a flight when fuel and oil is being consumed. Gross weight may also vary during a flight due to payload dropping or in flight refueling. At the time of releasing its brakes, the gross weight of an aircraft is equal to its takeoff…

1] Braking: The function of the braking system is to retard the speed of the moving vehicle or bring it to rest in the shortest possible distance whenever required. The vehicle can be held on an inclined surface against the pull of gravity by the application of a brake. Brakes are mechanical devices for increasing the…

1A) An H-bridge is a simple circuit that lets us to control a DC motor to go backward or forward.   In general an H-bridge is a rather simple circuit, containing four switching element, with the load at the center, in an H-like configuration: The switching elements (Q1..Q4) are usually bi-polar or FET transistors, in some…

1] Mapped models are used when the behavior of a particular model is not of our interest and can be modeled with predefined values in the form of lookup tables. eg: mapped motor: in the below model values are taken from experiments or old data  Implements a mapped motor and drive electronics operating in torque control…

  1] Select the metric unit and click on start. Change the load file to 'EV_defaults_in' Change the cargo mass to 500 and click on continue Now change the drive cycle to 'CYC_FTP' and # of cycles to 3, click on RUN Observation: We observe that vehicle can't travel 45 km. So, to travel 45 km with the FTP cycle we will…
