As the name suggests, the four words "extended range electric" in the Xingyue L extended range electric version are very not simple, because most plug-in hybrid vehicles will not deliberately emphasize the extended range mode in the series state, let alone use it to name. On the contrary, the Star Yue L extended range electric version has named the "extended range", here it is necessary to mention the Star Yue L extended range electric hybrid system working logic and its 3 speed variable frequency electric drive DHT Pro gearbox.

As we all know, most plug-in hybrid vehicles in the current car market have four driving modes: pure electric, series, parallel, and direct engine drive. The pure electric mode is easy to understand, and the power battery supplies power to the driving motor to drive the vehicle, which is equivalent to an electric vehicle. Only the pure electric range of the plug-in hybrid vehicle at this stage is concentrated in about 150km-200km, such as the M5 pure electric life of 200km, the ideal L8 pure electric life of only 175km, compared to the Star Yue L extended range electric version of 205km pure electric range is more advantageous, the daily charging frequency will be much less.

In series mode, when the power battery is insufficient, the engine supplies power to the power battery and the drive motor, and ultimately the drive motor drives the vehicle. Simple understanding, in fact, the series working condition is the "extended range mode", at this time the engine plays the role of generator and charging bank to power battery and drive motor power supply, at this time because the engine is in an efficient working range, so the energy consumption is not high. It should be noted here that because of the limited vehicle speed and battery power, most plug-in hybrid vehicles can not be in series conditions for a long time during the driving process, but switch back and forth in pure electric, series, parallel, and engine direct drive conditions.

Xingyue L extended range electric version is different, it has a separate extended range mode, and can be maintained for a long time, so that the energy consumption of the vehicle and the battery life are guaranteed. If the Xingyue L extended range electric version uses the extended range mode for the whole process, its driving range can reach 1250km, which is more advantageous than the 1100km of the M5 and the ideal L8.

Parallel mode is the engine and drive motor jointly drive the vehicle, that is, everyone is familiar with the electric mixing condition, at this time the performance of the vehicle to achieve the best state, in rapid acceleration and overtaking often appear. In fact, under the electric mixing condition, the working logic of the Xingyue L extended range electric hybrid system is the same as that of other plug-in hybrid models, the difference is that the Xingyue L extended range electric version is equipped with a 3-speed variable frequency electric drive DHT Pro transmission, which can make the power output of the driving motor and the engine have a wider speed, such as controlling the power output ratio by lifting the gear at high speed. On the one hand, it can reduce energy consumption, and on the other hand, it solves the problem of insufficient power at high speed of extended-range hybrid vehicles and single-gear direct-drive plug-in hybrid vehicles.
