The route-to-cell calculation ships as separate programs, and the joins are an interface nobody owns
1 / 6
The most complete chain in this work runs from a recorded path to the power a single cell sees. It is assembled from parts built by different groups, each of which stops at a different place.
The route is the dominant term, which is why a vehicle-normalised signature is noisy
2 / 6
A simulation sweep across driving cycle, ambient temperature, load and initial state of charge found the route taken to have the highest impact on energy consumption and depth of discharge. A separate framework built on a three-dimensional Markov chain with machine learning, validated on Tianjin and Xining, puts the electrification benefit across those two cities between 16.4% and 77.8%.

Battery health is now a number someone will insure, and it rests on a synthesised routine
3 / 6
The supplier-side paper in this work frames lifetime as a whole-vehicle development target forced by legal warranty minimums, and reaches its state-of-health prediction through a representative monthly power and temperature profile pushed through energy-flow simulation and a generic aging model.
Strategy
The tooling is the commitment: a generator given away, an optimiser bought
4 / 6
The upstream link is being released as a commons. Karlsruhe published a driving-profile generator in 2023 and again in late 2024, both times stating that an EV simulator is required to reach a current or power profile and is not in the package. emobpy turns mobility statistics into vehicle time series as an open tool, and Belfort-Montbéliard publishes an end-to-end model from GPX traces to cell power. A second release of the same generator eighteen months on is the maintenance behaviour of a group that expects others to build on it.
Research
The cell end is worked from both directions and the two do not meet
5 / 6
One dataset ages ten commercial INR18650 cells through an extended characterisation procedure: capacity, resistance, charging curves at several rates, and a WLTP-derived power profile replayed at different states of health. Measured forwards, that is what a drive profile does to a cell as it degrades.

Driver behaviour is sold as event counts, and the automaker holds the pipe
6 / 6
The review of driver identification in electric vehicles concludes that on-board sensor data collected in natural driving is the objective, accurate source for the task, and that the trend runs through deep hybrid models rather than any single channel. What the insurance market does with that is narrower: mileage, time of day, hard braking, hard acceleration and phone handling, priced into premiums.

What reaches buyers
The electric-versus-combustion choice is merchandised as four variants of one car
BMW's current 7 Series is one body sold as a mild-hybrid six, a mild-hybrid V8, a battery-electric sedan and a plug-in hybrid, launched together and priced as a ladder. That is how the comparison actually reaches a buyer: not as two powertrains to be measured against each other, but as trim levels of one platform sharing tooling and development.

Where the money goes
Durability is being engineered to a rule that arrives next November
The most explicit commitment in this material is a supplier building a method to a deadline. Magna's complete-vehicle paper says plainly that legal minimums for high-voltage battery warranty turn lifetime into a whole-vehicle development target, then sets out how it will be developed: a representative monthly power and temperature profile generated from user routine, ambient temperature and charging behaviour, pushed through energy-flow and thermal simulation, then through a generic cell aging model to a state of health over life, with sensitivity studies on charging, climate and operating strategy.
