One of the hardest tasks in electric vehicle routing is making good charging decisions -- namely, where to recharge and how long to do so. This is the crux of the fixed route vehicle charging problem (FRVCP). It's an important problem that we have to solve if we're going to adopt EVs en masse. Thankfully, an exact and efficient algorithm solving the FRVCP exists, but its implementation is sufficiently complex to deter people from using it.

frvcpy is an open-source Python package implementing this algorithm.

The Vehicle Routing Problem REPository (VRP-REP) is a place where researchers in vehicle routing can share information, like problem instances and solutions, in a common format. Mapper is a simple mapping utility for those instances and solutions. It's available on VRP-REP's website here.
