Tesla Leverages Software To Eke Out More Supercharging Capacity

Tesla Adds Charging Cap To Optimize Supercharger Network Availability

Tesla Adds Charging Cap To Optimize Supercharger Network Availability

In a push to increase the capacity of its Supercharging network at the top 8% of its stations in North America, Tesla is implementing a charging limit of 80%. During holidays, an additional 9% (for a total of 17%) of Supercharging stations will have the new charging restrictions put in place.

Tesla reached out to CleanTechnica this morning with the update and told us that the new charging cap is being put in place in parallel to the continued expansion of the Supercharging network, not as a stop gap that is being used in place of spending more capital to continue to expand the network. Much like the On-Route Battery Warmup solution, the new charging cap is a simple software push that adds value to all owners and increases the amount of kilowatt-hours the company can push out to vehicles with its Supercharging network.

Owners on road trips using the in-car navigation to determine charging stops and durations will not be affected by the new restriction, however, allowing owners traveling to more remote destinations the ability to charge up as much as recommended by the navigation system. Even in these situations, because the system optimizes the route for overall travel time, charging beyond 80% is an infrequent occurrence.

Implementing a software-limited charging cap of 80% at 8% of Supercharging stations may sound like a limit to freedoms, but the reality is that most people do not charge up to 100% … ever. That is because charging from 0–80% is when charging speeds peak, while charging from 80–100% takes far longer since charging speeds quickly taper off. Charging up beyond 90% also has long-term consequences for battery life, so keeping the state of charge lower is also the best way to ensure a long life for the vehicle’s battery.

The company estimates that the throughput at popular stations should improve by 34%. That translates to higher availability and faster Supercharging times for owners.

As part of the rollout of version 3 of its Supercharging network, Tesla said that it would be doing more than just installing more stations in a push to serve more than twice the number of vehicles with its Supercharging network by the end of 2019, something some close followers of Tesla Supercharging stations have noticed.

Tesla’s continued expansion of its Supercharging network will continue on into the future as its production, delivery, and sales capacity continue to grow year after year.

Tesla’s new version 3 Supercharging hardware is also coming in 2019 as the company begins deploying its new Supercharging backbone that splits a single 1 megawatt power feed into four dedicated 250kW charging stations. This new hardware raises the bar and continues to expand Tesla’s DC fast charging network as competitors continue to take pot shots from the sidelines about how their one fast charging station in a lab charged their prototype vehicle at 350kW. Cute, but Tesla is doing it today. Less talk, more action, thank you very much.
