There is no best EV route planner — there is a best planning tool, a best verification tool, and a best execution tool, and they are three different apps. A Better Route Planner (ABRP) plans the route. PlugShare tells you whether the plan’s stations actually work. Your in-car navigation executes the drive. Use one alone and you inherit its blind spot. Use the stack and the blind spots cancel.
That is the conclusion. Here is the test that produced it.
How we tested
We planned the same two corridors in every tool, then compared the plans against what the drives actually require — using our own corridor data and measured network reliability rather than the apps’ assumptions.
The corridors: I-90 Seattle→Spokane (298 miles, Snoqualmie Pass, then the thin stretch east of Moses Lake) and I-70 Denver→Grand Junction (244 miles, the Eisenhower Tunnel climb, the most demanding EV segment in our coverage area). Both are documented milepost-by-milepost in our I-90 and I-70 guides, which is what makes them useful test beds: we know what the right answer looks like.
A Better Route Planner: the best planner, with two blind spots
ABRP remains the most capable planning engine, and it is not close. It models your specific vehicle’s consumption curve, accounts for elevation (it priced the Eisenhower climb almost exactly right), adjusts for speed and temperature, and lets you set arrival buffers. The free tier plans both test corridors competently. Premium adds live traffic, weather integration, and real-time charger status.
Blind spot one: ABRP believes the rated speed. Its stop-duration estimates assume the charger delivers what the cabinet advertises. Our measurements say delivery runs 48–94% of rated depending on network. On the I-70 run, ABRP’s 22-minute estimate at a 350 kW site is a real-world 30–35 minutes for a 400V vehicle — per stop. The mechanics are in why charging stops run long; the practical fix is adding 25–50% to every ABRP stop estimate.
Blind spot two: ABRP believes the database. It routed our I-90 test through a station whose recent check-ins showed repeated session failures. The route was optimal only if the charger worked. Nothing in ABRP surfaces that risk.
Verdict: plan here, but audit the plan.
In-car navigation: the best executor, if you have the right car
Tesla’s in-car nav is the best single tool in this comparison — for Tesla drivers. It knows your true battery state and consumption in real time, sees live Supercharger occupancy, reroutes around waits, and preconditions the battery automatically before every stop, which is worth 30–40% of stop time in winter. On the I-90 run it produced the most accurate arrival predictions of any tool. Its limitation is the network boundary: it plans around Superchargers and treats everything else as secondary.
Non-Tesla native navs (Hyundai/Kia, Ford, GM, Rivian) have closed part of the gap — most now precondition when routed to a fast charger, which no phone app can do. Their planning engines remain weaker than ABRP’s. Use them as executors, not planners.
PlugShare: not a route planner, and that’s the point
PlugShare’s trip-planning feature is rudimentary — it drew plausible lines on both corridors but ignored vehicle consumption entirely. That is fine, because planning is not what PlugShare is for. Its check-ins are the only signal in this comparison that tells you whether a specific charger worked today. On our I-90 test it correctly flagged the problem station ABRP routed through. Reading the last three check-ins on every critical stop is the single highest-value five minutes in EV trip planning — the full verification method is in how to check a charger is working.
Google Maps: the quick-lookup tool
Google Maps now shows chargers, plug types, and sometimes live availability, and its EV routing on supported vehicles is improving. It still does not model your battery meaningfully on a phone. Use it to answer “is there a charger near this restaurant,” not “can I make Grand Junction.”
The verdict, and the stack
| Tool | Role | The blind spot |
|---|---|---|
| ABRP | Plan the route | Trusts rated speeds and stale databases |
| PlugShare | Verify critical stops | Can’t plan around your battery |
| In-car nav | Execute + precondition | Weaker planning, network bias |
| Google Maps | Quick lookups | Not a planner at all |
The stack: plan in ABRP with a 15–20% arrival buffer, verify every critical stop’s recent check-ins in PlugShare, then drive on the in-car nav so preconditioning works. Add the winter corrections from our mountain-pass guide between November and April, and know your fallback protocol for the stop that fails anyway.
One thing no app in this comparison provides is measured network reliability — which networks’ “available” stalls actually deliver sessions, at what speed. That data layer is why this site exists: the seven-network comparison is the audit we wish the planners built in.
