For today's consumers, buying a car is very tangled, because all kinds of energy forms have disadvantages.
The pure electric car model is called the future, but at least not now, the efficiency of energy supplement, the convenience of use, and the problem of battery life anxiety are all stubborn diseases that plague the growth of pure electric vehicle sales.
Although many people think that the plug-in hybrid model is more advanced than the range extender, the frustration and failure rate of the multi-gear DHT plug-in hybrid, the stall problem of the single-gear DHT plug-in hybrid, and the cost of multi-gear DHT with a large battery make consumers mutter.
The extended-range model is considered by many people to be no plug-in hybrid advanced, and the use of oil to generate electricity and then drive it is to take off the pants and fart, and the engine cannot be connected in parallel and directly, but on the whole, the extended-range model is already the optimal solution during the transition period.
Many problems of range extenders can actually be remedied, while the problems of plug-in hybrid and pure electric models are unsolvable at present.
For example, the energy consumption of the extended-range model running at high speed is slightly higher than that of the plug-in hybrid model, because it cannot be directly connected, but how much higher can it be? It is only one and a half liters, and if the extended-range model adds a large battery, it can also make up for the shortcomings of fuel consumption to a certain extent. Why can't plug-in hybrid models use large batteries? First, the cost is higher, and second, the volume is limited.
For example, the plug-in hybrid model can participate in the drive at medium and low speeds, so the power performance is often stronger, which can also be solved with a higher power motor.
The advantages of the range extender are also quite obvious, compared with the pure electric model, it has no range anxiety, after all, there are a few people who buy a car purely in the urban area, and the vast majority of families still need to occasionally run long distances, and the advantages of the range extender are reflected here. Compared with plug-in hybrid models, the range extender structure is simpler, the risk of stalling is lower, there is no frustration problem, and the cost is lower.
As the price of power batteries continues to decrease, the cost of large battery range extender solutions is getting lower and lower. Judging from the relevant price data, at the end of January 2024, the prices of iron-lithium power and iron-lithium energy storage cells fell to 0.38 yuan and 0.43 yuan/Wh respectively, and the price of ternary batteries fell to 0.48 yuan/Wh. The price of lithium iron phosphate batteries has been lower than 0.4 yuan/Wh, and the price of ternary lithium batteries has been lower than 0.5 yuan/Wh. The industry's goal this year is to reduce to 0.3 yuan/wh, even if the whole package is packed, the price of a 100-degree battery pack is only 40,000 yuan.
If a range-extended model is equipped with a 50-degree battery pack, the pure electric range is 400 kilometers, and a small power engine is equipped, then the urban commuting can be completely electric, even if the pure electric battery life is enough for cross-city traffic, and occasionally run a few long distances, it can also be very convenient to refuel, which is a more ideal solution.
Is there a car like this on the market? Leap's C01 and C11, with the blessing of a 43.7kWh large battery, have achieved a maximum of 316km of CLTC pure electric range, and the M5 extended range version is equipped with a 40-degree battery pack, and the maximum pure electric range has also reached 200 km, and the 28-degree battery used by Qiyuan A07 has a pure electric range of 200 km.
As for what many people are worried about, the battery capacity is large, and the weight has also gone up, in fact, it can be understood in this way, compared with pure electric models, the battery pack of the extended range is still much smaller, and with a set of internal combustion engines, it can achieve much longer battery life than pure electric models, and there is no endurance anxiety, calculated down, it is actually cost-effective.
It can be said that large battery range extension is currently the best solution to solve range anxiety and energy replenishment convenience. Of course, there must be many people who use the range extender to lag behind and have no technical content to attack the range extender model, it doesn't matter, let the people who fall asleep let them fall asleep, the growth rate of the range extender last year exceeded 140%, which can already explain everything.
