Energize Safely – Lithium-ion Battery Tips

​​​​​​​​​​​​​​​​Fires involving lithium-ion​​ batteries are growing concern in Brampton and the GTA. Lithium-ion batteries are safe when used correctly, but when they fail and ignite, they can cause a fire that can spread quickly out of control into a large fire, posing an immediate risk to people in the area.

Lithium-ion batteries are found in EVs, micro-mobility devices like electric scooters, e-bikes, and hover boards as well as e-cigarettes, smoke alarms, but are also the main power source for cell phones, laptops, tablets, toys, and countless other digital devices.

Lithium-ion batteries provide an effective and efficient source of power, however when damaged or improperly used, charged, or stored, the likelihood of them overheating, catching on fire, and even leading to explosions increases. These types of fires give off toxic gases and burn extremely hot. These gases are hazardous to firefighters and bystanders and can have lasting medical consequences.

  • All EV charging systems must carry an official mark or label of a recognized Canadian certification or evaluation agency.
  • Ensure you have a dedicated circuit to charge your EV to avoid using too much power too quickly from your home.
  • Hire a Licensed Electrical Contractor with an ECRA/ESA electrical contracting licence.
  • Ask your Licensed Electrical Contractor to file a notification of work with the Electrical Safety Authority (ESA) before starting the installation of charging system. Make sure your electrical panel can handle the extra load. If your panel needs an upgrade, contact your local utility.
  • If locating your charging system outside, ensure the system is rated for outdoor use.
  • Ask your Licensed Electrical Contractor to provide a Certificate of Acceptance once the work is completed and accepted. Your home insurance provider may ask you for it.
  • Keep charging cable off the floor to avoid a tripping hazard and to maintain the cord life.
