MG Motor will make its advanced electric vehicle battery available to a broader segment of consumers.
During a recent media briefing, Chen Cui, MG’s divisional general manager, announced that the forthcoming MG4 electric hatchback will incorporate a semi-solid-state battery. This power source has historically been exclusive to premium or conceptual vehicles.
The MG4 is slated for its official unveiling on August 5th. Its battery, sourced from QingTao Energy, utilizes a mere 5% liquid electrolyte, significantly bolstering its safety and stability. MG has also confirmed that the model has successfully undergone rigorous safety evaluations, including a comprehensive 360-degree puncture test.
Furthermore, MG claims that even at a chilly 19.4°F, the battery maintains 13.8% more range compared to conventional lithium-iron-phosphate (LFP) batteries. This presents a considerable advantage for motorists in colder regions, where EV battery efficiency and range typically suffer.
The innovative battery technology integrated into the new MG4 combines the benefits of solid-state and traditional liquid batteries through its semi-solid electrolyte. This design leads to substantial improvements in safety, energy density, and durability.
In contrast to standard lithium-ion batteries, semi-solid-state batteries mitigate the risk of overheating and fires, while concurrently offering extended driving ranges and quicker charging capabilities. The MG4’s battery is projected to deliver a range of 334 miles and boasts an energy density of 180 Wh/kg, thereby optimizing performance for daily use.
A 70 kWh battery pack powers the vehicle’s rear-mounted 120 kW electric motor, providing a single-motor, rear-wheel-drive setup. The MG4’s rear-wheel drive and balanced power output are expected to appeal to those seeking a more dynamic and engaging electric hatchback experience.
This setup could provide superior driving dynamics and performance when compared to some competitors.For example, the entry-level BYD Dolphin uses a 70 kW front-wheel-drive motor, while higher-end versions are equipped with a stronger 150 kW motor.
