The average monthly sales volume of 10,000 plus makes the ideal ONE a "net red car", and the precise positioning allows it to open up its own market, but at the beginning of the listing, everyone criticized its extender hybrid, and many consumers have not heard of this technology.
In fact, the basic structure of the extended-range hybrid is the hybrid of the tandem structure, that is, the engine, the generator, and the drive motor are connected in series in a power transmission path, and then the auxiliary power generation program composed of the engine and the generator is named "extended range system", which is the principle of the extended-range hybrid.
The range extender system is not directly involved in the drive of the vehicle, and only uses a generator to power the drive motor or battery alone or together.
Technical principles of ideal ONE extender hybrid:
Ideal ONE extender hybrid has a total of two use scenarios, we can simply understand that pure electricity is the main and the range is the main. If the charging conditions are superior, then the use of pure electricity-based mode, the vehicle will give priority to the use of the power battery power, only when the soC is reduced to about 30%, the range extender will intervene, through the capacity of 40.5 kWh battery, pure electric mileage up to 180 km, you can use it as a pure tram, charge at any time to ensure that the power is sufficient.
Then the charging conditions are not very good, can not always ensure the battery power, then the range extender mode is the mainstay, the range extender will be reduced to 70% of the battery SOC will intervene to start working, the range increase, but pay attention to the table SOC is less than 60%, in order to ensure that the power battery has enough power to cope with the power performance of the vehicle acceleration and other situations, the battery will no longer output power.
The ideal ONE extender hybrid range extender system has the following operating conditions:
1. Pure electric mode. The power battery outputs electrical energy to drive the motor, and the drive motor drives the vehicle, and this mode is only used when the soc of the table is not less than 70%.
2. When the battery power is less than 70%, the range extender starts to power the drive motor; when the power provided by the range extender is greater than the power required to drive the motor, the surplus power will be recycled into the battery pack, so that the power battery power is maintained at 70% of the threshold power. To be fully charged, you need to use a charging pile or portable charger.
3. In the case of overtaking, climbing and other cases that require high power, the range extender starts to power the drive motor, and the battery pack also supplies power to the drive motor and exerts the maximum power of the motor. In this mode, the battery drains quickly, and if the power battery is less than 60%, the battery will stop output.
Advantages of ideal ONE extender hybrid:
With a 40.5kWh battery pack, it can achieve a long period of pure electric endurance, and can be used as a tram in the case of good charging conditions, while the layout of the front and rear dual motors has the advantages of fast speed, fast power output and smoothness, and good quietness.
Disadvantages of ideal ONE extender hybrid:
Engine power is too low, which will lead to the engine conditions fluctuate very large, forced to support a wide range of operating conditions, if added to the air conditioning, entertainment system, rapid acceleration, uphill and other complex situations, the power system must have sufficient power reserves, and too small engine will continue to switch the working range because of various changes, fuel consumption will increase significantly.
At the same time, the power of the engine is too small, resulting in most of the actual power output being done by the battery, and in order to maintain the soC of the battery, a large amount of the engine's electricity is used to charge the battery. If you do not enter the range extension mode in advance, when the soC of the battery cannot be maintained, the engine will be fully loaded, and the fuel consumption may not even be able to guarantee the power demand of the vehicle.
Also because the engine working area is too wide, the physical defects of the three-cylinder engine will also be magnified, and the NVH performance will be reduced.
summary:
The ideal ONE extender hybrid system is a standard tandem structure, but through a larger battery pack, the pure electric mileage is increased, the charging conditions are superior and can be used as a pure tram, and the increased range mode can reduce the endurance anxiety.
The disadvantage is that the 1.2T three-cylinder engine, NVH performance will be reduced, while the low-power engine will lead to an increase in fuel consumption under complex working conditions, contrary to the purpose of fuel saving.
