We analyze the protection protocols and myths behind recent electrical incidents to ensure the safety of plug-in hybrid cars
The recent fire of several vehicles in a dealership in Leganés has set off alarms and raised doubts about the safety of the vehicles. plug-in hybrid cars. Many drivers in Benidorm, who use charging points in community garages or public stations on a daily basis, They are now wondering if it is dangerous to leave the vehicle connected for hours.
Although the causes of the Madrid incident are being investigated, experts agree that the safety of the hybrid cars pluggable is guaranteed by complex communication protocols. It’s not just about passing energy; the car and the charger constantly ‘talk’ to ensure that the battery never receives more power than it can thermally handle.
Differences between home charging and fast charging
It is essential to differentiate the equipment we use. On the one hand, he wallbox domestic, common in buildings in the Marina Baixa, charging using alternating current at low powers (between 3.7 and 11 kW). It is a slow and very safe process that can last overnight without compromising the installation.
On the other hand, Fast charging towers for public use handle direct current with powers that can reach 150 kW or more. These systems are much more sophisticated and have their own cooling. The most important thing is that the vehicle always has the last word: if the battery detects excessive heat, it orders the charger to reduce speed immediately.

What systems protect the safety of plug-in hybrid cars
For a serious accident to occur, normally Several protection systems must fail simultaneously. Current technology is designed to prevent anomalies by:
- Temperature sensors constants in each battery module.
- Intensity limiters which cut off the flow if there is a voltage spike.
- Galvanic isolation to avoid electrical discharges.
- Management software which disconnects the load when reaching 100%.
In extremely rare cases, an internal defect or previous damage from a hit to the underbody of the car could cause a thermal runaway. In this scenario, one cell heats up uncontrollably, affecting the others, a complex process to extinguish that requires specialized intervention from firefighters.
Real context versus alarmism
Despite the spectacular nature of this news, The safety of plug-in hybrid cars is very high. With more than 15 million electrified vehicles on European roads, incidents are statistically minimal.
The modern batteries They incorporate reinforced casings and intelligent management systems that make charging a car in a Benidorm parking lot a routine and safe task, as long as the electrical installation complies with current regulations and the vehicle is maintained correctly.
