If a fire bursts out in an EV or battery storage facility, the first instinct may be to grab the nearest hose. However, getting too close to the fire could spell disaster.

Although EV fires are very rare, if you do own an EV (or plan to in the future), there are a few steps you can take to tip the scale in your favour. First, get to know.Lithium batteries can produce hydrogen gas when mixed with water, which is flammable1. When excess current is passed in the battery, it can cause water to undergo electrolysis, which decomposes water into its constituent gases of hydrogen and oxygen. Hydrogen gas moves to the negative plate where it is then liberated into the atmosphere2. Lithium-ion batteries can emit dangerous gases such as carbon monoxide, hydrogen fluoride and hydrogen chloride when they catch fire3.

As the photovoltaic (PV) industry continues to evolve, advancements in Lithium battery hydrogen gas have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.
