With the rate of adoption of new energy vehicles, the manufacturing industry of power batteries is swiftly entering a rapid development trajectory.
On October 28, 2021, the Ministry of Industry and Information Technology issued the Notice on Launching the Pilot Work of Application of Battery Swapping Mode for New Energy Vehicles (hereinafter referred to as the “Notice”), deciding to launch the pilot work of application of battery swapping mode for new energy vehicles.
The battery swapping mode is one of the important ways of energy supply for new energy vehicles, which can effectively solve the pain points of slow and fast charging methods, alleviate the impact from the grid, improve battery safety, and have a positive promoting effect on improving the convenience and safety of NEVs.
This standard is the first basic universal national standard developed by the automotive industry in the field of battery swapping, which solves the problem of no standard for the battery swapping mode, helps guide enterprises in product research and development, and ensures the safety of battery-swapping-type vehicles.
The use of partial derivatives and first-order Taylor series expansion linearizes the battery model. The state-space model is linearized, and at each moment in time, it establishes an equation that correlates the projected battery value with the observed voltage .
Monte Carlo (MC) simulation is always used to forecast the battery swapping demand. With this information, DA optimization can determine the battery charging, discharging and swapping schedule, and the offering or bidding schedule for the market. 5. Programming and solutions
This is because battery life influences the period between exchanging a low stage-of-health (SOH) battery with a new battery; reduced battery value by different charging and discharging cycles and power is an important cost when considering the long-term operation of a BSCS. However, battery swapping is the main profit model of a BSCS.
