Measures in Case of an Emergency
Observing the tips in previous sections decreases the chance of an emergency for any e-bike owner, but unfortunately, incidents happen. So, familiarize yourself with the measures to keep yourself, your dear ones, or anybody around safe.
Generally, you can think of 3 steps when a fire starts on your Li-ion battery:
Depending on the size and type of battery, there are various ways to put off a Li-ion battery fire. You need to be quick to react and prevent fire from spreading.
Since fires caused by Lithium-ion batteries are Class B fires, you should opt for a standard ABC or dry chemical fire extinguisher. Class B classification is to distinguish the flammable liquids. Because Lithium-ion batteries contain liquid electrolytes, they fall into this category.
When burning, the poisonous liquid acts as a conductive pathway for fire and helps it spread faster.
You can use the extinguisher to spray the fire until it is put out. The stages are as follows:
- Pull out the safety pin to use the extinguisher.
- Target the nozzle at the base of the fire.
- Squeeze the handle firmly
- To ensure that you put out the fire wholly and correctly, sweep the nozzle back and forth across its base.
- Take the battery out of the building:
If you suspect something is wrong (e.g., the Battery case getting warm, liquid leaking, or the battery making noises), you should put it outside in a safe, open space and wait for the battery to go back to normal. Please note, do not try to handle the battery that has caught fire or leaking fluids as it can be hazardous to you.
If the battery catches fire, wait for all the cells to burn while trying to extinguish it.
- Call the fire department:
Li-ion battery fires are thermal runaway events type. Subsequently, e-bike battery fires can pose several hazards, like poisonous smoke, flames, and metal projectiles. After taking the necessary measures explained above, you should call the nearest fire station in your area if you cannot contain the fire.
Judge the severity of the situation and do not approach the burning battery. Wait until firefighters arrive if you are not comfortable dealing with the fire.
What Safety Features Do ENVO Lithium Battery for Ebikes Contain?
To ensure our products live up to your highest quality and safety expectations, ENVO has sought and awarded the first UL 2849 ebike certificate in Canada.
Recent progress in BMS (Battery Management Systems) has led to better control of the battery pack in e-bikes from several perspectives, like the battery working and its charging and discharging. The final goal of ENVO is to optimize the performance and longevity of its batteries.
Though we ensure to provide e-bike batteries that exceed industry standards Following are some of the safety features of ENVO Batteries.
- Charging Protection (Voltage and Current)
ENVO Batteries cut off charging if the charging voltage or current gets higher than the definite range; this ensures that charging is discontinued in case of any fault.
Cell balancing improves the available capacity of the battery; additionally, unbalanced cells can be damaged and cause failure in the long run.
This is why ENVO Batteries come with cell balancing and cell balancing cutoff. This way, the battery is shut down if one of the cells is permanently damaged and cannot be balanced.
- Discharge Protection (Voltage and Current)
During the operation of the product, the voltage and current value are measured; if the voltage gets too low or the current value gets too high, the BMS cuts off the battery for safety reasons.
Short-circuit in Li-ion batteries are always dangerous. It may damage your battery and decrease its lifecycle at best. And at worst, a short circuit can lead to severe risks like a lithium battery fire or burst, causing injury, property damage, or even death.
ENVO Batteries include short circuit protection designed to monitor the battery's voltage to prevent hazardous situations arising from short circuits in the batteries.
- Temperature Cutoff Protection
Envo Li-Ion batteries include a temperature cutoff protection mechanism that shuts down the battery when the temperature value exceeds the safe limit.
