The main health risks associated with lithium-ion batteries in EV charging stations stem primarily from their potential to overheat, catch fire, or explode. These risks can expose people to heat, smoke, toxic gases, and physical injury. Specifically:
- Fire and Explosion Hazards: Lithium-ion batteries can overheat due to mishandling, improper charging or storage, physical damage, or manufacturing defects. This overheating can lead to thermal runaway, a chain reaction causing intense fires or explosions. Explosions can project battery fragments over significant distances, causing multiple fires and physical harm.
- Release of Toxic and Corrosive Gases: When lithium-ion batteries catch fire, they release hazardous gases such as hydrogen fluoride and carbon monoxide. These toxic fumes can cause acute and chronic respiratory problems and chemical burns to eyes and skin if inhaled or contacted.
- Chemical Burns and Skin Damage: The electrolyte fluid inside lithium-ion batteries is flammable and corrosive. If the battery casing is damaged or overheated, this fluid can leak, posing a risk of skin and eye burns or other injuries upon contact.
- Electrical Shock: Improper use or damage of batteries and chargers may increase the risk of electrical shock, particularly during charging if safety procedures are not followed.
- Fire Safety Infrastructure Concerns: Due to these risks, fire safety measures at EV charging stations, such as sprinkler systems and proper fire protection planning, are crucial to mitigate damage and health hazards should an incident occur.
In summary, the primary health risks are from fire and explosions leading to burns and trauma, inhalation of toxic smoke causing respiratory harm, chemical exposure causing burns, and electrical hazards during battery charging. Proper handling, infrastructure, and safety protocols are needed to reduce these risks at EV charging stations.
