Recently the hardware has invented an electric car spring is coming

Recently the hardware has invented an "electric car spring coming?" "After the Netizen responds positively, why not carefully contrast the popular Tesla and already commercial domestic electric vehicle." Driven by factors such as higher oil prices and higher environmental requirements, the Commercial Vehicle window has been opened.

As one media peer put it, if you haven't seen a pure electric car a few years ago, maybe it's because they're probably walking around in harsh environmental testing areas and now they are going to show up.

But how many people will be able to accept electric cars? is a problem. Electric cars now show two extreme attitudes, one is to put a product like Tesla in the sky, the technology of the big guys are all flocking.

The other is a variety of domestic electric cars distrust, we can in all aspects to compare, the domestic electric cars and Tesla for the representative of the foreign electric car differences, the value is not trustworthy in the daily use.

At present the domestic market you can buy the pure electric vehicle, most is from the domestic brand. Foreign brands are only BMW and the new Tesla. I chose these representatives:

Foreign car companies have been driving electric cars for years, such as Nissan's Leaf, BMW's i3/active E/mini E, the GM's volt of electric cars, and so on, but few of the joint ventures have entered the domestic market. Fortunately, Tesla came, coupled with a domestic joint venture to launch the first volume production of the electric car Springo, so I found these two representatives.

1, Tesla

2, Theo Springo

Domestic electric vehicle representatives have more, into the Ministry of the new Energy car catalog of the domestic car has ten good several, the brand involves BYD, BAIC, SAIC, Jianghuai, Kai-chen, etc., selected three of the market can already be bought.

1, BYD E6

2, SAIC-E50

3, North Steam E150ev

EV users are most concerned about these aspects: first, the mileage. Ii. security. Third, one-time input costs. Four, the late maintenance costs, and so on, the following parameters to do a comparison.

The domestic car is enough

Can see, for the above several problems, the endurance has been able to reach more than 120 kilometers, of course, this is related to driving conditions, such as Isaiah Springo, integrated operating conditions can travel 130 kilometers, if the average 60 km open to 200 km.

More than 100 kilometers of endurance in the city commuting is not a problem, in addition to Tesla's "abnormal" mileage, the joint venture and other three domestic electric vehicles are similar, BYD E6 can reach 300 kilometers.

Another concern in terms of endurance is charging time, which now has two charging standards. The State Grid charge pile, the other is 220V ordinary charging pile. General general charging time is 6-8 hours, if the high current DC fast charge can improve the charging time, or in half an hour to 1 hours time, can fill 50% of the electricity, this involves the public charge pile and personal use of the charge pile, public charging pile to meet the needs of rapid charging, The charge pile can be recharged at night.

Battery safety

Another is safety, leakage, spontaneous combustion, explosion this is a large number of battery-loaded pure electric vehicles, the public concerns. Now most of the domestic electric vehicles are lithium iron phosphate batteries. The thermal stability and structural stability of lithium iron phosphate materials are the highest in all cathode materials from the thermodynamic aspect.

So the energy density of lithium iron phosphate batteries is no higher than those of some batteries, but the safety is much better than theirs.

Tesla, however, uses a specially tailored NCA18650 lithium cobalt-oxide battery, which is made up of more than 7,000 PCs with a single 3100mAh capacity. The highest level of security has been achieved. This battery technology is mature, more than the energy (to participate in the electrode reaction of the unit quality of the electrode material release power of the size) than BYD used lithium iron phosphate battery higher.

Another fact can be left to prove lithium iron phosphate electromagnetic or reliable, can see the general Volt example, the general Volt is in the United States, the mass production of electric vehicles, began with the LG cooperation of the three yuan material electromagnetic, and then because the Volt appeared futures reasons. The use of iron phosphate batteries began, so the domestic introduction of the Springo also used iron sulfate batteries.

Overall, the safety of the battery, Tesla is more than the domestic lithium iron sulfate battery electric car higher. The safety of electric vehicles remains to be verified, but the current manufacturers have reached the highest level possible. Crash tests are also required for the Ministry of the testing.

Upfront investment costs

The inescapable fact is that electric cars are still too expensive, and that Tesla's positioning is "luxury cars", priced at more than 700,000. Several other civilian electric vehicles, the price is not civilian? The official guided prices are 200,000 +.

However, there are subsidies for new energy vehicles in big cities such as the north, Guangzhou and Shenzhen. But depending on the region, the policy is quite different. BYD E6, for example, can enjoy 120,000 of the subsidy in Shenzhen and only 60,000 yuan in other places. According to the situation, the general subsidy cost reached about 100,000 yuan. So, the actual investment in buying pure electric cars now is probably the equivalent of a Class A home car (E6 and Tesla are relatively expensive).

But Tesla has yet to qualify for the subsidy, saying, who cares about the subsidy for the people who buy Tesla?

Aftermarket and later investment

This is the upfront investment cost, and then one is the late input cost. This is precisely the advantage of pure electric vehicles. For new energy vehicles, from my comparison of these cars can be seen, the general manufacturers of batteries and cars after the sale of separate years.

And the battery after the sale of life is generally longer than the length of the vehicle, such as the North Steam E150 EV, the whole car is 3 years 60,000 kilometers, the battery for 8 years. This point, whether domestic or foreign brands, the difference is not big.

Summary：

In combination with the above points, domestic pure electric vehicles and foreign-owned pure electric cars, in addition to the face like Tesla's luxury cars, domestic electric vehicles in the range and security settings, luxurious function settings to be inferior to many outside. Domestic pure electric vehicles and General Motors such as the foreign brands of ordinary electric vehicles, life mileage, the use of battery material security, charging time, after-sale warranty period, there is little difference.

On the contrary, domestic pure electric vehicles in the policy of financial subsidies more preferential treatment, if it is early adopters of the user, completely can choose domestic pure electric vehicles. In addition to government subsidies, now like Guangzhou and Beijing, in the context of buying a car, a dedicated green channel for pure electric vehicles, is also a good opportunity.
