How long does the hybrid car battery last? Does the hybrid car need to change the battery?

Hybrid cars have been seen everywhere in our lives, but the most puzzling thing is how long the Hybrid Car Battery can last, and the need to replace the battery in the end of the hybrid car. The following is a summary based on the conclusions of the netizens. See below for details. .

The answer to the question of whether the hybrid car needs to change the battery is affirmative. After all, the battery has a shelf life. If it is not replaced, it may cause a large power consumption, that is, the energy saving effect is not good.

The battery of a car has to go through a process of charging and discharging every day. If it is calculated according to the use of 350 days a year, then the battery can be recycled for 1200 times. The usage period is about three years, two years. The need to replace the battery once, mainly refers to the use of the battery is too frequent, and this does not mean that the battery is completely unusable, just like the mobile phone battery, but the capacitance is reduced, which we are targeting Plug-in hybrid models.

For a weakly mixed battery like Toyota, which is not plugged in, it is more durable, and Toyota has already implemented a separate warranty policy for the battery in the sale of the hybrid car, which is basically life-long maintenance-free. Therefore, it takes a lot of time for the hybrid car to change the battery for two years. Moreover, the development of hybrid vehicles will definitely become the mainstream in the future, and the durability of the battery will definitely be further improved.

The battery of the domestic standard hybrid vehicle is also a Lithium Battery, which is the same as the lithium battery of a pure electric vehicle. According to the manufacturer's warranty, it is generally 5-8 years. Of course, this refers to the normal use. The lithium battery that has passed the warranty period can still be used, but the capacity of the lithium battery will drop more (more than 20%) at that time. The energy saving effect is not very good. You can decide whether to replace the battery according to your own conditions.

Everyone’s concerns about the Toyota Hybrid Battery are not unreasonable. After all, after using the battery on laptops and smart phones for a year and a half, the storage capacity will inevitably decline. Then he gave birth to the rumor that "the Toyota hybrid car will replace the battery every three years." In fact, Toyota uses the battery method and the electronic product is essentially different. The digital product battery charging basically adopts the deep charge and deep release method, that is, the low battery is used to fill the battery once, which is actually the biggest culprit of the battery life. .

Toyota Hybrid uses a shallow-charge multi-cycle strategy, which generally only uses 10% of battery capacity when driving in urban areas. Even in the most extreme cases, the maximum battery consumption is only 40%. In other words, about 60% of the battery's power is never used, which guarantees "light charging." Toyota Hybrid can recover energy during braking and taxiing, so charging is quite frequent. This is called “multi-cycle”. This kind of strategy can greatly improve the life of the battery, and in view of the battery of electronic devices such as notebooks, in order to ensure the use time, the discharge amount will exceed 80% of the battery capacity.

If you feel that the above theoretical analysis is difficult to understand, I will use real examples to illustrate. First of all, Toyota Hybrid launch time is much longer than many people think, the first generation of Prius was born in 1997. It was originally only for domestic sales in Japan. It was only exported to other countries in 2000, so many people are still quite strange to it. But today, even if we can't use google, we can't find the case of the first generation Prius to replace the battery.

More convincing, a test by the US media "Consumer Report", taking a first-generation Prius that has been used for 10 years and has a mileage of 330,000 kilometers, and the Prius new car data measured 10 years ago. comparing. As can be seen from the above table, no matter the fuel economy and acceleration performance, the old and new cars are almost the same. Even if it is a traditionally powered car, the degree of recession will not be the same after the same age of depreciation.

Another example of the reliability of Toyota's batteries is the Prius taxis that are active in the world, and there is no shortage of Hong Kong in China. Toyota has recycled many taxis with a mileage of more than 200,000 kilometers. Among them, even the mileage of the car exceeds 500,000 kilometers. No one has replaced the battery in the middle, and even the battery failure has not happened! There is a more extreme example. Canada's Andrew Grant is the world's first taxi driver to use the Prius. The car was purchased in 2004, until the car retired in 2012, the mileage exceeded 1.5 million kilometers, and the battery performance remained. outstanding. It can be seen that the life of the Toyota hybrid Car Battery is not lower than the traditional mechanical part! It is fuel-efficient and reliable, and it is no exaggeration to call the Prius the “returning tool” of taxi drivers.
