What is the working principle of Toyota THS fourth-generation hybrid?

[DiEliza]

Taking a series hybrid electric vehicle as an example, its working principle is as follows: At the beginning of the vehicle's operation, the battery is in a fully charged state, and its energy output can meet the vehicle's requirements, so the auxiliary power system does not need to work; when the battery level drops below 60%, the auxiliary power system starts. The relevant details are as follows: 1. Vehicle energy demand: When the vehicle's energy demand is high, the auxiliary power system and the battery pack simultaneously provide energy to the drive system; when the vehicle's energy demand is low, the auxiliary power system not only provides energy to the drive system but also charges the battery pack. 2. Battery pack: The presence of the battery pack allows the engine to operate under relatively stable conditions, thereby improving emissions. Not all hybrid vehicles rely on electric motors, batteries, and wires. Some vehicles are driven by the combined action of hydraulic engines, neutral lines, and accumulators.
