On January 18, 2022, CATL released its power exchange service brand EVOGO Lexing power exchange, and the overall solution of combined power exchange. The overall solution of combined power exchange is composed of three major products of "power exchange block, quick change station and APP", and the first batch will launch the EVOGO power exchange service in 10 cities.
Different from the AL-BASED power exchange system, EVOGO further splits the battery pack concept and launches a chocolate power exchange block (Choco SEB) that can be exchanged according to the battery module. Each chocolate swap block can provide a NEDC cruising range of about 200km, and the bicycle supports up to 3 chocolate swap blocks.
"Chocolate battery changer" is a mass-produced battery specially developed for the realization of shared power exchange, with three characteristics: small and high energy, free combination and minimalist design. Using the latest CTP technology of the Ningde era, the weight energy density of the "chocolate exchange block" exceeds 160Wh/kg, the volume energy density exceeds 325Wh/L, and a single battery can provide an endurance of about 200 kilometers, and can adapt to the pure electric platform developed by 80% of the world's 80% that have been listed and will be listed in the next 3 years. Consumers can choose one or more batteries at will when changing the power, flexibly matching the needs of different mileages. In addition, the "chocolate changer block" adopts wireless BMS technology, and only has a high-voltage positive and negative interface on the outside, which greatly improves the reliability of the plugged and unplugged components.
Based on the innovative combination of power exchange overall solutions, Times Electric Service has created a new service brand of EVOGO, and given it three major characteristics: one electricity multi-vehicle, on-demand rental electricity, and rechargeable and replaceable.
Different from the traditional power exchange mode, EVOGO realizes two "one power and multiple vehicles" full adaptation scenarios. The "Chocolate Bar" can be applied to passenger cars from A00 to B and C and logistics vehicles. The substation can be adapted to the use of "chocolate power exchange block" of various brand models, breaking through the adaptation barrier between the battery and the model, and realizing the freedom of choice of the power exchange model.
Consumers can "rent electricity on demand" and freely choose the number of rented replacement blocks according to their own usage scenarios and habits. At present, most private car owners will only use 10-20% of the battery power in the daily use scenario, but in order to alleviate the mileage anxiety and energy replenishment anxiety, they have to buy large-power models and pay a lot of sunk costs. With "rent electricity on demand," consumers commute around the city on a daily basis and only need to rent one block. If you want to travel long distances, you can choose two or three electric blocks, which can really increase or decrease, and realize the freedom of electricity.
The express change station has four characteristics: small area, fast circulation, large capacity and full climate. Each standard station only needs three parking spaces, a single block to change power for about 1 minute, the station can store 48 power exchange blocks, to ensure that users always have a full power block can be replaced, no need to wait for a long time. At the same time, the substation can also be provided with versions adapted to the climatic and environmental conditions of different regions.
As can be seen from the above table, the installed power battery capacity of the Ningde era in 2021 is 80.51GWh, accounting for 52.1% of the domestic market, far ahead of BYD, which ranks second, and occupies half of the domestic power battery market.
In order to better cope with challenges and resist risks, the Ningde era has given car companies more choices when building cars by releasing the EVOGO replacement brand to integrate into more new models. At the same time, the existing market position and market share also help them to better layout and coordinate the power exchange business.
The Cataline era into the game, the release of the power exchange brand EVOGO can be described as a deliberate plan, as early as July 2020, the Ningde era and Futian Zhilan new energy joined hands to begin to layout in the field of new energy replacement. The BaaS (Battery as a Service, battery rental service) business launched by Weilai also has the figure of the Ningde era behind it.
Finally, a brief list of the advantages of the power exchange model and its significance for the new energy vehicle market:
1) Shorten the energy replenishment time and make up for the low efficiency of the charging mode
2) It helps to realize the separation of vehicle electricity and reduce the cost of car purchase, while the unified management of the battery can also strengthen safety and improve the gradient utilization efficiency
3) Optimize power utilization and balance power resources at peaks and valleys
