Are current Accord hybrid batteries just lithium batteries?

Although the US version of the Hybrid Kai achieves an incredible fuel economy of 52/51/53MPG, this version is the lowest configuration, uses lithium batteries and is the lightest. The US version of the Hybrid Kai with mid-to-high configurations uses nickel-metal hydride batteries instead, making the car heavier. Its fuel economy is only 46/44/47 MPG, which is about the same as the Malibu hybrid and not as much. as good as the Accord Hybrid. The joint venture version of Hybrid Kai also uses nickel metal hydride and vehicle weight ratio

How long does a hybrid car's battery last?

What is the difference between the lithium-ion battery in the Accord Hybrid and the nickel-metal hydride battery in the Camry Hybrid? Which one has more stable performance and more durability? The difference between the two liese in the fact that only Toyota hybrids use nickel-metal hydride batteries, while almost all electric vehicles use lithium batteries.

Characteristics of nickel-metal hydride batteries and lithium batteries

Characteristics of nickel-metal hydride batteries:

1. Lower cost than lithium batteries;

3. Performance is relatively stable, security. is better and is less affected by temperature;

4. The battery has a memory effect when charging and discharging

5. small and the weight is great;

6. Fast charging and discharging performance is good and can be used in pulse charging;

7. The lifespan is shorter thane that of lithium batteries.

Characteristics of lithium batteries:

1. There is no memory effect and can be charged as needed

2. the weight is lighter;

3. The voltage is higher, but the current is smaller;

4. The lifespan is longer but the cost is also higher.

Which hybrid is better, Toyota or Honda?

By understanding the characteristics of the two batteries, we can understand why Toyota and Honda chose two power batteries.

For Toyota, the engine drives the vehicle most of the time, and the engine only plays an auxiliary role, so the battery requirements are less, so the nickel hydride battery Cheaper metal is naturally It is the first choice, and the price of lithium batteries was relatively high when the Toyota hybrid was developed. However, even if nickel-hydride batteries mmetal are used, there is no need to worry about their durability, because Toyota only charges and discharges shallowly, which does not cause much damage to the battery. According to surveys, the Prius in Vancouver, Canada can travel an average of 700,000 kilometers stably. Therefore, its advantages over Honda hybrids are proven reliability, lower maintenance and repair costs and better resistance to low temperatures, but its performance is relatively low and fuel consumption is worse.

For Honda, because it uses batteries to directly drive the engine most of the time, it has higher requirements for battery life, charging and discharging performance , capacity and volume, it therefore chose lithium batteries. According to real-world measurements, the Honda hybrid can already achieve efficiency and performancesuperior to those of the Toyota hybrid. However, due to its short launch time, its reliability has not yet been verified. According to Honda official data, the battery life of Honda hybrid is more than 50,000 times in ten years, and the battery is still 80% charged and discharged after 5 times.% capacity. If this data is true, Honda hybrid electric can easily be used for hundreds of thousands of kilometers.

So although the Honda and Toyota hybrids use lithium batteries and nickel-metal hydride batteries respectively, they each have their own advantages. In comparison, Honda has higher performance and Toyota's reliability has been improved. would you choose?

How long does a hybrid car battery last?

To myAs new energy vehicle technology continues to mature, new energy vehicles are accepted by more and more people. In addition, compared with fuel vehicles, the cost of new energy vehicles is much lower. New energy vehicles on the market today include pure electric vehicles and hybrid vehicles. Compared with pure electric vehicles, hybrid vehicles have more advantages and are more popular with consumers.

However, some consumers also have certain questions about hybrid cars. For example, how long does a hybrid car's battery last? How much does it cost to replace it? Regarding these two issues, you will understand by continuing to read below.

Before explaining the battery life of hybrid cars, let's first talk about the advantages of hybrid cars. What nWhat we usually call hybrid vehicles generally refers to gasoline-electric hybrid vehicles. Its advantages mainly include the following points. The first point is fuel economy. Gasoline-electric hybrid vehicles feature both fuel engine and pure electric drive, which can significantly reduce fuel consumption, and car owners do not need to change their fuel consumption habits. use of the car. The second point is its strong power performance, especially when starting up. With the help of the electric motor, the starting speed is much faster than that of a gasoline vehicle.

Having talked about the benefits of hybrid cars, now let's get back to the topic. There are three types of batteries used in hybrid vehicles, namely ternary lithium batteries, lithium iron phosphate batteries and au nickel metal hydride. Among them, ternary lithium batteries and lithium iron phosphate batteries are both lithium ion batteries. The life of ternary lithium batteries is about 1,000 times, and that of lithium iron phosphate is about 2,000 times of their life. two batteries last about 10 years. The lifespan of nickel-metal hydride batteries is approximately 500 cycles. If it exceeds this value, battery life will be significantly reduced. The replacement cost of these batteries is mainly related to the battery capacity. The larger the battery capacity, the higher the battery cost.

In fact, if you want to extend the life of a hybrid car battery, daily maintenance is very important. First of all, we must understand the charging time when charging and do not charge more than ten hours continuously. Overloading will cause thebattery, thereby affecting its lifespan. When the battery is fully charged we can unplug it. Secondly, when the battery is about to run out, we need to charge it in time. Since batteries are stored in a depleted state, they are prone to sulfation, leading to insufficient charging and a decrease in their capacity. And the longer the power loss time, the more damage the battery will have.

In addition, we need to pay attention to the battery storage environment. It cannot be stored in an environment above 60℃ or -30℃ for a long time. If the storage environment temperature is too low, the power battery will not be sufficiently charged and its capacity will decrease. During the discharge process, the battery life may be reduced.

In general, hybrid car batteries have a relatively long lifespanEU and the replacement cost is not particularly high. And with the innovation of battery technology, these problems will be properly solved in the future.
