The potential for Electric Armoured Fighting Vehicles (E-AFVs) is explored in this discussion. E-AFVs face electrical component challenges, particularly in tanks, where various systems rely on electricity, including radio, night vision devices, and computer systems. Tanks utilize batteries charged by the main engine, and some incorporate auxiliary engines to extend battery life quietly.
Silent operation is crucial in tactical situations, but heavy battery drain occurs during startup. Some tanks use air starting systems to address this issue, where air bottles charged by a compressor aid engine ignition. Replacing a tank’s engine with an electric motor necessitates large, high-energy-density batteries, presenting design challenges due to limited space and added weight.
Although lithium-ion batteries offer higher energy density than lead acid batteries, further advancements are needed. Replacing lead acid batteries with lithium-ion ones can increase silent watch capabilities, reducing noise and heat signatures.
Lighter Armoured Personnel Carriers (APCs) or Infantry Combat Vehicles (ICVs) may benefit from electric power, with the potential for fully electric ICVs in non-combat roles. However, the availability of electricity in battle areas poses a challenge, making hybrid ICVs a viable option. Hybrid vehicles offer reduced fuel consumption and logistical advantages.
E-AFVs have a torque advantage, providing high torque at slow speeds, enhancing agility. They do not require gears, simplifying operation. Additionally, E-AFVs can move silently, a valuable tactical advantage. A combination of electric and internal combustion engines in hybrid ICVs appears promising.
In tracked ICVs, mechanical drives connect the engine to the tracks, adding weight. In contrast, electric ICVs have individual electric motors at each wheel, improving maneuverability. These motors can be controlled via computer systems, allowing for different drive configurations and enhanced traction.
E-AFVs, with sealed electric motors, can operate effectively in amphibious conditions, offering greater flexibility for water propulsion compared to mechanical systems.
Maintenance requirements for electric vehicles are typically lower than internal combustion engines, especially in dusty desert environments. Reduction in liquid fuel storage lowers the fire hazard risk, making electric or hybrid vehicles advantageous.
Standardized battery packs across all vehicles could simplify logistics and support various battery-powered equipment in battle areas.
The civilian electric vehicle industry’s technological advancements, including improved batteries and motors, suggest that electric or hybrid armoured fighting vehicles may soon become a reality in military operations.
