YOGYAKARTA - The use of electric vehicles such as motorbikes and electric cars in recent years has increased. However, behind its environmentally friendly advantage, there is actually a hidden danger that must be known, namely the thermal runaway. What is the thermal runaway?

This phenomenon risks causing fires to explosions in electric vehicle batteries. For those of you who use electric cars, electric motors, or even electric bicycles, understanding this risk is certainly very important in order to maintain safety.

Thermal runaway is one of the biggest risks of lithium-ion batteries operating on electric vehicles. When the battery temperature increases and gets out of control, there will be a chain chemical reaction that can trigger an explosion.

This is of course directly related to charging, short circuits, or physical damage in battery cells. So, the battery can emit smoke, catch fire, and even explode if it is not repaired immediately.

Reporting from the Astra page, thermal runaway is a condition when lithium-ion batteries experience an extreme temperature rise that cannot be controlled. This process generally starts from one battery cell that experiences problems, and then spreads to another cell due to a chain reaction.

This condition can cause extreme heat and emit black smoke, so it is very dangerous if it occurs in motorcycles and electric cars that are being used.

The increase in battery temperature can come from various sources, for example too high electric currents, electricity in unstable batteries, or overheated environmental thermals.

There are several factors that can trigger the risk of a thermal runaway in electric vehicles. Below are some of the main causes:

The risk of thermal runaways not only occurs from within the system, but is also triggered by the surrounding environment and user treatment of batteries. Therefore, it is better for electric vehicle owners to always monitor and provide regular battery maintenance.

When the battery experiences a thermal runaway, the process can occur very quickly. Electricity that experiences spikes, rising temperatures, and increasing internal pressure on the battery could trigger a fire, even an explosion.

This of course not only causes damage to vehicles, but can also be life-threatening. Several incidents noted that electric cars caught fire while they were parked or while charging.

The pungent smell, an abnormal temperature indicator, or the emergence of smoke from the vehicle body must be watched out for.

Battery Management System (BMS) is a vital component in the electric vehicle battery system. BMS functions to monitor the electricity, temperature, and voltage of each cell in the battery to prevent overcharging and overheating.

With the function of BMS, potential risks such as fires can be reduced to a minimum. This technology can also detect physical damage or hard collisions that can damage battery components.

With a crucial prevention function, BMS is key to battery security. Performance and safety of electric vehicles will be vulnerable to interference without reliable BMS functions.

That's a review of what the thermal runaway is, the cause, and the fatal impact. Hopefully useful. Visit VOI.id to get other interesting information.
