The new policies of the network taxis and the implementation rules of various places have been introduced in the near future. Since November 1st, this new format has also begun to get on the right track. In the choice of models, new energy vehicles have obvious advantages. This article only analyzes an important indicator “the warranty period of power batteriesâ€, so that companies and individuals can choose carefully.
New energy network about taxis if you choose to rent a purchase (for example: choose a certain model, the company requires the franchise of the driver to pay 20,000 yuan, 4,800 yuan a month, after three years, the vehicle exits the operation, the company will transfer the car free of charge The mode of operation of the driver as a private car, whether the driver can be recognized and joined, is the key to whether this mode can be activated, and the driver's biggest concern is how to evaluate the residual value of the car after the three-year period of transfer. ? That is to say, the problem of participating in the network taxi operation value is not worthwhile.
Why is the used car market difficult to evaluate for new energy vehicles? First, new energy vehicles have not entered the WTO for a long time, and there are still few used car transactions. Second, the industry has no rules for evaluating new energy vehicles. The biggest reason is the largest proportion of vehicle batteries. Compared with: plug-in hybrid electric vehicles account for about 1/3, pure electric vehicles account for about 1/2, pure electric logistics vehicles account for about 3/4). The technical routes are too different, the warranty period is too different, and the existing used The car appraisers have their own qualifications and abilities. Specifically:
First, the battery difference
The power batteries currently used are mainly lithium series batteries, and the main ones that can be used for electric vehicles are lithium iron phosphate, ternary, lithium manganate, etc. The most controversial ones are the first two. Because the ternary battery has the advantages of higher specific energy (longer cruising range) and lower procurement cost, most passenger car manufacturers prefer to use this battery when producing pure electric passenger cars; but the ternary battery is Safety (the state is currently suspended for passenger cars), service life (when the charging capacity is attenuated to 80%, the ternary battery is generally full about 1500-2000 times, and the lithium iron phosphate battery is full about 4,000 times) Not as good as a lithium iron phosphate battery. It can be seen that the use of a ternary battery is beneficial to the vehicle manufacturing plant, and the use of a lithium iron phosphate battery is advantageous to the consumer of the vehicle.
Second, the difference in warranty period
Because of the differences in the above-mentioned battery technology routes, it is worried that automobile manufacturers will use ternary batteries too much in order to reduce their navigation and reduce costs. Therefore, the state proposed last year that the power battery warranty period for passenger electric vehicles should not be less than 8 years or 120,000 kilometers. The threshold of this threshold, a considerable number of car manufacturers and battery manufacturers have indicated that it is difficult to achieve under the existing technical conditions!
Therefore, the battery warranty period of the electric vehicles currently operating in the market is set to be relatively low, such as 8 years or 120,000 kilometers, 8 years or 150,000 kilometers, etc.; and some automobile manufacturers use It is a lithium strontium phosphate (or lithium iron manganese phosphate) battery. Under the premise of ensuring the attenuation performance of the existing battery charging capacity, it promises a lifetime warranty for the non-operating vehicle of the passenger car range, and the operating vehicle promises 8 years. Or 500,000 km battery warranty. There has been a doubling of the battery warranty period.
Third, the significance of consideration
1. Because the network taxi is mainly used for operation, there is no time for slow charging during the operation. Therefore, only the public DC fast charge can be used. The fast charge of the year will also accelerate the battery decline; the full-time taxi The annual operating mileage is about 100,000 kilometers. If the warranty period of the battery is short, the battery life will be shortened due to the attenuation of the battery capacity after only one year of operation. Therefore, it will no longer be suitable for operation. If you want to continue operation, you will definitely Faced with the problem of replacing the battery at your own expense, it will also greatly increase the cost of its use!
2. The existing vehicle power battery, regardless of the technical route, the cost is basically greater than 2000 yuan / KWh, and the pure electric vehicle used for network rental operation, the cruising range needs to meet more than 250 kilometers, that is, loading The power battery capacity is generally around 40-50KWh, that is, the replacement of the primary battery requires an increase of more than 100,000 yuan (not yet measured according to the current industry's common parts zero ratio), this will increase the cost of use later. Can't ignore it at all!
In view of this, it is recommended that companies and individuals who work in taxis to pay attention to this factor when selecting new energy vehicles; it is also recommended to provide a solution to the new energy vehicles in the taxi market to solve this problem.
