Through the previous explanation, you must have a certain understanding of the classification of electric cars, but if you want to buy electric vehicles, just understand how its category is clear enough. As the power source of electric vehicles, the power source of electric vehicles has always been regarded as an important iconic technology for the development of electric vehicles. It is also an important bottleneck that restricts electric vehicle development. Its performance is directly related to the long and short-term life, so master some and batteries. The relevant basic knowledge is helpful for purchasing electric vehicles in the future.● Battery classification batteries can be mainly divided into three major categories: chemical batteries, physical batteries, and bio-batteries, with chemical batteries and physical batteries have been applied to mass production electric vehicles, and biotech is considered a future electric vehicle. One of the important development directions of the battery. For the current practical application, we only introduce chemical batteries and physical batteries. If you are interested in bio-batteries, please refer to other information separately.
■ Chemical cell
Chemical batteries are the most widely used battery types in electric vehicles, such as nickel-hydrogen batteries, lithium-ion batteries, lithium polymer batteries, fuel cells, etc. belong to this field. From a structural point of view, it can be further divided into two major categories of battery and fuel cells, and most electric vehicles we have seen are driven by battery technology, such as Toyota Puri, Tesla Model S. Of course, the battery that is mentioned here is not our daily car battery, but a collective replicate rechargeable battery, where the lead battery usually used lead-acid batteries is only one of the segmentation.
Due to the large type of electric vehicle battery, a large part has been eliminated by the current market, and it is impossible to explain the principle of its obscure. It cannot help the actual car, so we will pass through a form to roughly understand these batteries. Type and basic characteristics
■ Physical battery
The physical battery is the name suggests, relying on physical changes, storing electricity batteries, such as super capacitors, flywheel batteries, and family members that are physical batteries.
The super capacitor is a power supply element between the conventional capacitance and the battery mainly relying on the two-electric layer and the redox fake capacitance charge storage electrical energy, and the chemical reaction is not generated during the period, and therefore is classified as a physical battery. Compared with the chemical cells previously introduced, the super capacitors have three obvious advantages, first of all, their repeated charge is hundreds of thousands of times (traditional chemical batteries only have hundreds to thousands), and there is a lot of indigenous batteries. Secondly, the super capacitor is extremely high in power density at the time of charge and discharge, and instantly can release a large amount of electrical energy, which can meet the more wide power demand for vehicles; third, the work environment is better, usually the outdoor temperature is at -40 ° C-65 ° C When it is stable and normal (traditional batteries are generally -20 ° C ~ 60 ° C).
Of course, there is an advantageous, and the low energy density is the primary bottleneck that restricts the development of supercapacitance. Therefore, it is currently used in the vehicle launch system, military and small bus vehicles. As for the use of a household vehicle power supply, it is necessary Waiting for energy density puzzle, it can be seen after a breakthrough.
The flywheel battery is a new concept battery proposed in the 1990s and is also a physical battery. Simply put using the principle that generates energy when rotating similar to the flywheel is used to realize itself. In the last round of the United States Le Mans Series in October 2010, the Porsche 911 GT3 hybrid racing car officially used flywheel battery technology, and it was the predecessor of the famous Porsche 918 Spyder. However, the flywheel batteries of these two models are only used for assistive energy, and their functions are similar to our common brake energy recovery system. Even so, we still have reason to believe that with the continuous development of technology and further decrease, the application prospect of the flywheel battery will be very broad.
