Tesla has just started rolling out its latest wireless upgrade, the number 2022.16.0.2 in their electric cars. In her improves the prediction of energy consumption during the route including new data related to the meteorology, adds an option to select the combined braking and open the option multi-accounts on Spotify for each user. But in addition, it incorporates relevant information that probably has a lot to do with the opening of Superchargers to electric cars of other brands: now it is possible to know the time you have to wait at each station to be able to rechargegar.
Tesla was the pioneer of OTA wireless updates (over the air). A function that has been so successful that other manufacturers try to offer it with more or less success in their electric cars. Updates don’t just introduce new features or improve the user experience, they can sometimes fix a software issue that prevents the need for a shop. That Tesla update its software now shouldn’t be newsbecause it is something he usually does, although in this case the inclusion of new options it can be considered relevant.
Wait times at Superchargers
Tesla has long offered through its car navigator the occupancy rate of the Superchargers of each of its stations. However, this information is not sufficient since it was not possible to know how long did you have to wait to be able to load in case everyone was busy. Now at last, Tesla has included this information.
In each of them, you know the recharging power that you are supplying, the SOC of the car battery that you are charging, and the percentage that you must reach. With this data it is possible to know how much time each car has left to finish recharging. Together with the information of the vehicles that they plan to recharge at each station, coming from the routes calculated by their navigators, Tesla has all the data to know approximately the time remaining for a Supercharger to become free. Information that is now offered on the screens of all its electric cars.
This feature will be very useful to Tesla owners. now that the Supercharger network is open to the rest of the electric cars on the market and a greater influx is expected. Thanks to this information, users of a Tesla will be able to decide if they want to wait the time indicated by the navigator or change their route to avoid waiting.
Energy consumption calculations
Along with the waiting time for recharging, Tesla has implemented some functions that are also very interesting. The first of hers is a better estimate of the energy consumed by your cars during a route. When a destination is entered in the browser, the software will consider various weather-related parameters to estimate consumption: crosswind, headwind, humidity and ambient temperature, according to local forecasts. This information allows calculating with greater precision the energy with which the destination or an intermediate recharging point is reached.
The remaining autonomy calculations are complicated to carry out both for the case of an electric car and for a combustion car. The parameters that affect consumption are so many and so variable that the errors in these algorithms can be considered common. However, it is very important that it be as accurate as possible to eliminate the famous “anxiety of autonomy”. Despite Tesla’s software expertise, it still makes mistakes in energy consumption during a trip.
In 2018, Tesla already added factors as important as the orography (ascents and descents on the route) and some conditioning factors of the local climate. All this helped to improve the calculation, but it was still inaccurate, because it depends on the speed at which you drive, the environmental conditions, the traffic conditions and other factors that influence efficiency. While these factors may seem like a small percentage of the difference on some long trips, they can be significant. That is why Tesla continues to improve its algorithms by including more data and using it as conveniently as possible to refine the calculation.
With the new OTA, Tesla has also included an update to the combined braking. This option can now be selected via the menu Controls>Pedals & Steering>Apply Brakes When Regenerative Braking Is Limited. Combined braking helps hydraulic brakes to supplement regenerative braking when regenerative braking is limited due to battery temperature or state of charge (when the battery is completely full and braking energy cannot be stored in the battery). decelerations).
Finally, there is one more function that is added to Tesla electric cars, which is the possibility of having multiple active Spotify accounts depending on which user profile is selected in the car. That is, the accounts are now linked to the driver’s profile.
