Most Common Electric Car Breakdown, Impossible To Guess | Incredible

BEVs (Battery Electric Vehicle) fresh from production generally do not register so many failures. Judging by the most recent statistics, however, it is surprising that the most common breakdown of electric cars has been discovered.

The data collected on Reddit confirm what theADACthe German Automobile Club that manages roadside assistance and has accurate statistics on the origin of breakdowns.

You know what it is main cause of electric car breakdowns? The answer will leave you speechless.

The most common breakdown of electric cars is paradoxical

The ADAC reported that, in 2021, there was an increase in emergency calls of 178%: the figure is not surprising considering the increase in circulating electric vehicles. Out of 25 thousand cases, the percentage of interventions rose to 0.72%: a rate that remains low, mainly due to the young age of the cars.

According to the latest statistics recorded, the German Automobile Club reports an absurd figure: the main cause of emergency requests in Germany is not the battery pack that powers the engine but the 12 Volt accessory battery.

According to 2020 data, this small lead-acid battery was the leading cause of failure in 54% of cases against 4.4% deriving from the battery pack (the heart of the BEVs), from the recharging devices or from the engine. Rarely, these last three elements are responsible for failures.

Reddit confirms the cause of the most common failure of electric cars

Even the most recent data European and American statistics confirm this reality: the 12 V battery (for services, not for propulsion) is the number one cause linked to the need for roadside assistance for an electric car. The reasons for this ‘behavior’ of the battery do not differ much from those related to thermal cars. The large battery modules are not responsible for frequent failures on green cars but the small battery useful for services.

The American site Reddit, to understand the most frequent cause of electric car breakdowns, it involved its users. The respondents’ response confirms, once more, the problem: the little one 12 Volt service battery.

Why is the 12V battery the BEV’s Achilles heel?

There 12 V lead acid battery it is the same that is used to power ancillary services (interior lighting, electric locks, etc.). This accumulator has a particular mole: it is negatively affected by extreme temperatures (freezing or very hot).

The small battery recharges from the main ones when the car is running. The biggest risk is when it remains in stand-by for too long because, not recharging with the other batteries, it can go empty. When this happens, the car won’t start, the doors won’t unlock, you can’t open the hood and you’re forced to call for assistance.
