MG Comet EV
MG Motor, a subsidiary vehicle firm of SAIC Motor, China launched its compact EV automobile named MG Comet EV within the first week of this month (Could) and its reserving began on the 15Th of Could. This automobile is manufactured in its Halol plant, in Gujarat. This automobile is a 4-seater with a complete size of the automobile is 2.97 m and a turning circle radius of 4.2 m. So, this automobile is straightforward to drive within the metropolis. Its beginning value is Rs.7.98 Lacs and is available in three variants-Tempo, Play, and Plush with 5 colours.
MG Comet has a curb weight of 815 kg and with a full cost offers a spread of 230 km. MG in its Comet phase has competitors with Tata Tiago EV that begins at Rs 8.69 lacs and it has additionally three variants promising a spread of 250 km for its base variant XE.
MG Comet Motor Sort
A single Everlasting magnet synchronous motor (PMSM) of energy 41.43 hp that may generate most torque of 110 Nm is utilized in MG Comet EV for propulsion. The motor is put in within the rear axle. PMSM motor has a everlasting magnet on the rotor and winding on the stator.
PMSM resembles the development properties of each Induction and BLDC motors. The everlasting magnet on the rotor and the windings on the stators are comparable in development to the BLDC motor. The stator form with winding development is offering a sinusoidal flux density which is analogous to an induction motor.
PMSM is used over BLDC and Induction motors as a result of it’s extra environment friendly, smaller in measurement as in comparison with different forms of motors, gives full torque at low speeds, requires much less upkeep as no brushes are concerned for commutation, and has mature know-how for its mass manufacturing. So, these causes attracted MG Motor to make use of PMSM in its Comet mannequin. The corporate is offering 3 years or 1Lakh km of guarantee on its powertrain (motor). Even in Tata Tiago EV, PMSM is used that having 45 kW of energy.
Battery Capability and Sort of Battery Chemistry
LFP (lithium-iron-phosphate) primarily based Li-ion battery of capability 17.3 kWh is utilized in MG Comet to energy the propulsion system of this automobile. It may be charged totally in 7 hours with a 3.2 kW charger (AC Sort 2) that may present a spread of 230 km. LFP-based Li-ion battery gives larger cycle, low self-discharge, and good security requirements as in comparison with different chemistry-based Li-ion battery like NMC, LCO.
The battery pack utilized in MG Comet has a prismatic kind issue (out of essentially the most generally used cylindrical, pouch, and prismatic). Prismatic cell reduces the dimensions of the battery pack making electrical vehicles compact in measurement however faces thermal points as in comparison with cylindrical cell.

MG Motor has offered 8 years or 1.2 Lakh km of guarantee on its Comet’s battery pack. This battery pack has an IP67 ranking defending the battery pack from water and dirt. As per sources, MG Comet battery is equipped by Tata AutoComp which has a tie-up with Chinese language battery provider Gotion. Tata Tiago EV battery pack is available in 19.2 kW and 24 kW of capability.
