If you run out of “juice” in the electric car, this is a bigger problem than when the fuel is spent in the tank of a regular car. You don’t take electricity in the canist. How does an electric car behave in such a situation and what to do? To do this, the German ADAC test is answered, which he checked in the crisis situation of six electric vehicles. The differences are interesting.

There are no jokes with a discharged electric car. Usually there is nothing else to do but take him to the charger. But what is happening before? To do this, the ADAC test gives an answer.
The battery capacity in electric vehicles is gradually increasing and the network of charging stations is also thickened. Nevertheless, coincidentally, a number of unexpected circumstances may happen that the electric car is completely discharged, kilometers in front of the charger. Nobody would like to experience this, but as they say “Coincidence is a jerk”. There is few information on how electric cars behave when energy drops below their battery. It has a reason. Each electric car owner is careful not to be in a similar crisis. He does not take electricity in the canist. However, you dared to do the biggest German ADAC. He checked six different electric vehicles at the border of their possibilities.
First two warnings
Each car, before the ADAC test, charged 20 to 30 percent and then circled on a closed circuit of the former air base in pension until they were discharged. And without trying to extend the range to the maximum, as the driver of an electric car would do in a situation where there is a threateningly low percentage of battery charge on the display and the range shrinks to a minimum. ADAC found that the biggest differences are what dramaturgy of the warning of electric vehicles they offer before discharging. There are two warnings. The first warning comes in most cars quite early when the display shows a range of 40 to 80 kilometers or 15 to 20 percent of battery charging.

Often, the battery symbol lights up to orange or the message appears: “The battery is poorly charged” or “Recharge the battery soon”. At the first warning you do not feel any differences in the behavior of the car. Everything works as usual and you still have enough power reserve. However, if you continue to drive and get to the second warning, acoustic warnings will be added and the graphic ones will be intensified depending on the model. Some models will recommend austerity measures at this stage, such as selecting ECO driving or reducing air conditioning or heating. However, you can still drive safely, although you already feel a loss of performance in sharp acceleration.

ADAC – what with a discharged electric car This was what it looked like during the test on the former military haze of pension.
At this point, you should already unconditionally leave the highway, because when the range drops to a single -digit number, many electric vehicles will limit performance even more noticeable. Simply, the situation becomes serious, although the car still works. Over time, however, zero range and zero battery charge appear on the display. Some electric vehicles at this stage display a turtle on the display, Chinese bybish displayed only a dash instead of zero range. However, this still does not mean that your electric car will turn off like a smartphone. The difference is that it will switch to the “emergency reserve“. This reserve is kept by the electric car for emergency situations.
Then an emergency reserve
In the test, six electric vehicles with this emergency reserve managed to pass 15 to 20 kilometers at 50 km/h. So you should still get to a charger. However, ADAC points out that you should be really careful, because electric vehicles only work with fractional performance and can stop at any time. Even after stopping, some of the cars tested managed to move a few meters. Shutdown and starting can help. Often, however, nothing works in such a “undercut” the car. Therefore, the emergency regime should be avoided. It can be explicitly dangerous in real traffic.

However, if the electric car is completely discharged, do not count on the methods of solution that are common for a car with an empty tank. You have to call a “pull -out”. As a rule, electric vehicles must not be pulled, otherwise the electric motor could generate voltage and destroy its own electrical system. Simply, you need to get to the charger. In rare cases, you can help charge another electric car with the Type 2 connector. However, it takes a long time. For five to ten kilometers, count for 30 minutes or earlier for an hour. You will have to find a patient donor.
