Properly deployed public charging stations are important foundations for the large-scale operation of electric taxis. This paper proposes a novel framework for the deployment of public charging stations, which takes into consideration the effects of passengers, taxi drivers, electricity retailers, transportation network, distribution network, and power consumers. First, on the premise that public charging stations have already been deployed, an agent-based model is constructed to simulate the charging demands of each station, considering passengers' travel demands and retailers' mutual competition. Second, to obtain candidate sites for public charging stations, the critical node index is put forward based on the massive trajectory data of taxis. Finally, a multi-objective optimizing model for public charging station deployment is proposed with charging demand simulation embedded. By traversing candidate sites and quantities of charging spots at each station using a modified genetic algorithm, the optimal deployment results are obtained. The framework and models are demonstrated and verified by a test case. The results indicate that the proposed framework could minimize the costs of charging stations, electric utilities, electric taxi drivers, and passengers while lowering the load heterogeneity in the distribution network at the same time. INDEX TERMS Electric taxi, load heterogeneity, multi-agent simulation, pricing strategy, public charging station planning, trajectory data mining.

Controlling charge‐spin current conversion by electric fields is crucial in spintronic devices, which can now be realized in diatom ferroelectric semiconductor GeTe. It is well demonstrated that ferroelectricity can change the spin texture in this compound. Herein, it is shown that the spin Hall conductivity (SHC) can be further tuned by ferroelectricity based on the density functional theory calculations. The spin texture variation driven by the electric fields is elucidated from the symmetry point of view, highlighting the interlocked spin and orbital degrees of freedom. It is observed that the origin of SHC can be attributed to the Rashba effect and the intrinsic spin–orbit coupling. The magnitude of one component of SHC σxyz can reach as large as 100 ℏ/e false(Ω−1 cm−1false) in the vicinity of the band edge, which is promising for engineering spintronic devices. The work on tunable spin transport properties via the ferroelectric polarization brings novel assets into the field of spintronics.
