Battery pack cooperation mode

Can a power battery supplier cooperate with a new energy vehicle manufacturer?

Considering the supply chain composed of a power battery supplier and a new energy vehicle manufacturer, under the carbon cap-and-trade policy, this paper studies the different cooperation modes between the manufacturer and the supplier as well as their strategies for green technology and power battery production.

Are Power Battery R&D and cooperation strategies under carbon cap & trade policy?

Therefore, this paper will try to explore the power battery R&D and cooperation strategies of new energy vehicle manufacturers under the government’s carbon cap and trade policy, considering the three strategies of wholesale purchase, patent-licensed manufacturing, and self-research + wholesale purchase, respectively.

What is a battery module - pack?

In the context of batteries being used in vehicles, the general configuration is: battery cell - module - PACK. However, this method only achieves a space utilization of 40%, significantly limiting the space for other components. The development of battery integration (CTP, CTC, CTB) is gradually becoming the key research and application direction of the industry.

How do manufacturers and suppliers cooperate in power batteries?

According to the different ways of cooperation between manufacturers and suppliers about power batteries, we constructed the game models under three strategies: wholesale purchase, patent-licensed manufacturing, and self-research + wholesale purchase, and solved them by applying Stackelberg’s game theory and the asymmetric Nash game theory.

How can a stable cooperation mode be formed?

Changes in parameters such as costs and benefits and alliance cooperation intensity will break the deadlock to a certain extent. Then, some stable cooperation mode can be formed gradually.

What is the final cooperation mode?

The final cooperation mode depends on initial strategy ratio (x 0, y 0) and the relative position of the saddle point ( x*, y* ), If ( x0, y0) is in the left zone of ( x*, y* ), within the OADC region in Figure 3 b, (0, 0) indicates the stable fixed point.
