At what speed does a hybrid electric vehicle use electricity?

[Mateo]

Hybrid electric vehicles use electricity at speeds below 25 km/h, with fuel consumption approximately around 4 liters. Here is some extended information: Function: Hybrid electric generally refers to the combination of fuel and electric power. The output characteristics of internal combustion engines and electric motors are opposite; electric motors can deliver strong torque at low speeds, providing ample power for vehicle acceleration from a standstill. In contrast, internal combustion engines increase their output power and torque as the speed rises, supplying power for mid-to-high-speed acceleration. Besides enhancing the vehicle's power performance, hybrid electric systems can also significantly improve fuel economy. Types of hybrid electric systems: There are various forms of hybrid electric systems, broadly categorized into hybrid electric vehicles (HEV) without external charging capability and plug-in hybrid electric vehicles (PHEV) that can be charged externally.
