Net booking taxi New Deal, the implementation of detailed rules have been issued recently, since November 1 began this new format also began to enter the right track. In the choice of models, new energy vehicles have obvious advantages, this paper only on an important index "power lithium ion battery warranty period" to analyze, so that companies and individuals in the industry carefully choose.
If you choose to hire a car instead of buying it (e.g. When selecting a certain type of car, the company requires the drivers who join to make a down payment of 20,000 yuan and a monthly payment of 4,800 yuan. After 3 years, the vehicle will withdraw from operation, and the company will transfer the ownership of the car to the driver for free as a private car). Whether the driver can recognize and join is the key to the start of this mode. The driver's biggest concern is how to evaluate the residual value of the car after three years of ownership transfer? In other words, it is worth to participate in the operation of online taxi service.
Why is it difficult to evaluate new energy vehicles in the used car market now? First, it is not long time for new energy vehicles to enter the WTO, and there are few second-hand car transactions; Second, there is no evaluation standard for new energy vehicles in the industry to follow; The biggest reason is that the power lithium ion battery, which accounts for the largest proportion of vehicle value (value proportion: plug-in hybrid vehicles account for about 1/3, pure electric vehicles account for about 1/2, and pure electric logistics vehicles account for about 3/4), has too big difference in technical route, too big difference in quality guarantee period, and the existing second-hand car appraisers do not have the qualification and ability to determine. Specific as follows:
First, battery difference: the power lithium ion battery is important for lithium series battery, can be used for electric vehicles is important lithium iron phosphate, three yuan, lithium manganese acid, etc., the most controversial is the first two. Because the ternary battery has the advantages of high energy (long range) and low supporting procurement cost, most passenger car manufacturers are inclined to use this kind of battery when producing pure electric passenger cars. However, the three-way battery is not as good as the lithium iron phosphate battery in terms of safety (the country is currently delaying its use in passenger cars) and service life (when the charging capacity decays to 80%, the three-way battery is generally full of about 1500-2000 times, while the lithium iron phosphate battery is full of about 4000 times). It can be seen that the use of ternary batteries is beneficial to vehicle manufacturers, and the use of lithium iron phosphate batteries is beneficial to consumers of vehicles.
Ii. Warranty period differences: Because of the differences in battery technology route, worry about automobile manufacturer to show momentum, cost reduction, excessive use ternary battery, so the country put forward by use of electric cars last year power lithium ion battery warranty period shall not be less than 8 years or 120000 kilometers, the threshold of the hard and fast rules, quite a lot of automobile manufacturer and battery plant under the condition of existing technologies that are difficult to achieve!
Therefore, the battery warranty period of electric vehicles currently operating in the market is set at a relatively low level by most automobile manufacturers, such as 8 years or 120,000 km, 8 years or 150,000 km, etc. However, some automobile manufacturers use lithium iron phosphate (or lithium iron manganese phosphate) batteries. On the premise of ensuring the attenuation performance of the existing battery charging capacity, they have promised lifetime battery warranty for non-operating vehicles in the range of passenger cars, and 8 years or 500,000 km battery warranty for operating vehicles. The battery warranty period has multiplied.
Iii. Significance of Consideration:
1, network taxi is important for operation, there is no time to slow charge in the operation process, so can only use public DC fast charge, perennial fast charge will also accelerate the decline of the battery; About taxi years full-time network running mileage is about 100000 km, if the battery warranty period short, operating more than a year after only the battery capacity attenuation will allow range greatly shortened, will therefore no longer suitable for operation, if you want to continue to operate, will face the question of whether or not to replace the battery at one's own expenses, will also cause the cost increase!
2. The cost of the existing vehicle power lithium ion battery, no matter what kind of technology route, is basically more than 2000 yuan /KWh, while the range of the pure electric vehicle used for online rental operation should be more than 250 km, that is, the capacity of the loaded power lithium ion battery is generally about 40-50kwh. That is to say, the new cost of replacing the battery is more than 100,000 yuan (it has not been calculated according to the current common parts and components ratio in the industry), and the new use cost in this later period cannot be ignored at all!
In view of this, it is suggested that companies and individuals in the online taxi industry pay attention to this factor when choosing new energy vehicles; It is also suggested that manufacturers of new energy vehicles supplied to the online taxi market seriously solve this problem.
