The domestic development of charging and swapping stations, the difference between battery swapping

The differences between battery swap stations and charging piles are as follows:

1. Compatibility.

Compared with the charging pile, although the battery swap station can provide energy supply for new energy vehicles, in terms of compatibility, the battery swap station is far less than the charging pile. Because the charging pile has no requirements for the brand or model of the new energy vehicle, it can be charged; However, the battery swap station is diametrically opposed, so the battery swap station is more restricted.

2. Charging efficiency.

In terms of charging efficiency, the advantages of the battery swap station are very obvious, from the new energy vehicle into the battery swap station to the completion of the battery swap, it only takes ten minutes. The charging pile is not as good as the battery swap station in terms of charging efficiency, and the time is longer. However, some battery swap stations have problems such as insufficient maintenance and insufficient charging power, which will also affect the charging efficiency.

Precautions for car charging

1. Daily charging: It can make the battery in a shallow cycle state and prolong the service life of the battery.

2. Grasp the charging time and frequency: Overcharging, over-discharging and under-charging will shorten the life of the battery, and the charging time and frequency should be grasped to avoid damage to the battery.

3. Avoid plugging hair heat when charging: too long heating time will cause short circuit or poor contact of the plug, damage to the charger and battery, and the oxide should be removed in time or the connector should be replaced by Nian Lushan.

Charging stations are only for electric vehicles.

Charging the battery pack, similar to a gas station; The battery swap station is to remove all the battery packs that need to be charged for electric vehicles, and then replace them with battery packs of the same type that have been fully charged. It can be simply understood as a battery swapping station.

Electric vehicle charging stations, mobile phone charging stations and car gas stations are similar in that they are devices that "power up" batteries and mobile phones. It is a high-efficiency charger that can quickly charge electric vehicles, mobile phones, electric tricycles, old scooters, etc. "Electric vehicle fast charging stations" and hand charging stations can be set up in shops, neighborhoods, newsstands, car storage sheds, betting points, etc., just like car gas stations.

The electric vehicle charging station adopts pulse, which has a good desulfurization effect, can activate the battery first, and then carry out maintenance fast charging, with timing, full alarm, computer fast charging, password control, self-identification voltage, multiple protection, four-way output and other functions, supporting universal output interface, can quickly charge all electric vehicles.

Principle: AC --- charging pile--- AC - on-board charger - DC --- battery charging. [i] Charging station [i] includes: ordinary charging, fast charging and battery replacement[i], which is a comprehensive vehicle charging place.

To put it simply, the charging station can be understood as the electric vehicle charging pile in the daily common community, a version of equipment.

It can charge 10 electric power bullet trains, generally one yuan for 4 hours, and slow charging.

The battery swap station can be understood as leasing batteries, the battery is charged in the cabinet, and the general lithium battery is the majority, if the electric car has no power, it will go to the nearby site to charge, which is more convenient and safer, but it is currently installed in the community is relatively small, generally more on the street side of some stores, and the takeaway delivery personnel use more.

Common charging piles in the community.

NIO already has a variety of power supply solutions such as home charging, home fast charging, and overcharging, so why should it need time-consuming, laborious and expensive self-built battery swap stations?

1. The ultimate customer experience.

Take JD.com as an example, in 2011, JD.com was engaged in 211 time-limited delivery. Same-day delivery was achieved in big cities, and at that time, Jingdong engaged in this extremely high-speed distribution, and the cost was very high.

But JD.com insisted on doing so, and eventually accumulated a large number of loyal customers through a "beyond expectations" user experience.

In terms of customer experience, in some scenarios, the experience of battery swapping is better than charging, and loyal customers are cultivated through a better customer experience.

2. The need for financing.

So far, NIO has not been able to make a profit, and it has relied on financing and blood transfusion.

If the performance and functions are completely homogeneous compared with competitors such as Tesla and BYD, it will gradually reduce competitiveness. The more references a customer has when choosing, the less likely you are to be favored by a customer.

3. The need for capital operation.

NIO is one of the few private enterprises that cooperates with several well-known state-owned enterprises at the same time, and signed a framework agreement with Guodian in 2020, and the two parties agreed to build 500 battery swap stations in 2021; In 2021, it signed a cooperation agreement with Sinopec, and the two sides agreed to build 5,000 battery swap stations by 2025.

In fact, the cooperation with central enterprises is not the listed NIO, but the battery company of NIO. NIO spun off the battery company and undertook the heavy responsibility of transfusing blood to listed companies, on the one hand, doing the hardest and most tiring work, and on the other hand, assisting listed companies to optimize their financial statements.

For example, through the policy of renting batteries, the transfer of sales revenue is realized (when the customer rents the battery, the battery company buys the battery from the listed part and then signs a lease agreement with the customer).

4. Correct interpretation of new energy support policies.

In order to encourage the healthy development of new energy vehicles, the new energy subsidy has strict regulations on the price of automobiles, and medium and high-end models exceeding 300,000 yuan will not be subsidized.

However, battery swapping is not an exception.

Regardless of whether this policy is open to NIO alone, or NIO's sensitive sense of smell has long anticipated this policy, anyway, NIO's products can enjoy subsidies while surpassing the ordinary electric vehicle ** system.

In fact, I don't think this standard is prepared for NIO alone, because from the perspective of state-owned assets in the battery swap business, it is prepared.

Comparing the key points of new energy vehicle standardization released in 2018 and 2020, it will be found that not only the battery swap business, but also the power battery cascade utilization, wireless charging, power battery size standards, etc., have been laid out in advance.

NIO has a very thorough understanding of policy.

The charging and swapping station is an energy station that provides charging and rapid replacement of the power battery of electric vehicles. In order for an electric vehicle to run continuously, it needs to be replenished with electrical energy. The supplement of electric energy can be divided into two types: vehicle charging (fast charging, conventional charging and slow charging) and fast hand speed replacement of the defeated battery.
