Running out of fuel was certainly a problem with cars with internal combustion engines, but often easily solved with a simple tank and a distributor nearby. With the’electric car we often joke about the use of giant power bankswhich is not proposed by any manufacturer.
There is actually a category of products that could be used for this purpose, namely accumulators with lithium batteries, designed for work, life in a camper or anyway recreational situations. So the usual youtuber Bjrn Nyland wondered if it really could work:
The test was performed with a Tesla Model Y and an accumulator EcoFlow Delta Maxa model with a capacity of 2 kWh and power supply up to 2.4 kW on alternating current sockets. The question that often arises whether the weight of these products can somehow nullify any additional autonomy, but in the case in question the only ones 22 kg EcoFlow seem to be quite irrelevant in terms of opposition to vehicle advancement.
The combination of accumulator, home charging cable and internal car charger made one possible power of 2 kWit’s a recharge equal to 1.4 kWh, passing this (via a car battery data reading device) from 29 kWh to 30.4 kWh. Consequently, the author of the video drove until the value returned to 29 kWh, totaling about 11 km.
In conclusion, it can be said that the system works on a technical level, but it can only be useful if you are in areas with columns installed in a capillary manner. Alternatively, you could try with higher capacity accumulators, risking that excessive weight starts to become a negative factor.
