Firefighting for electric vehicles with lithium-ion batteries
The number of electric vehicle registrations is rising rapidly, and the trend is upwards. Electric vehicles do not burn more frequently, as some popular magazines might suggest, but they are definitely different!
E-car on fire?
Firefighting in connection with high-voltage batteries (HV batteries) therefore poses new challenges for the emergency services and requires more time.
Which extinguishing agent for electric vehicles?
The extinguishing agent recommended by the trade associations AGBF, vfdb and the German Fire Brigade Association is quite clear: water.
As with firefighting on vehicles with combustion engines, it is also expedient to use extinguishing foam occasionally.
SnakE is suitable for both normal water and extinguishing foam or wetting agent.
What are the challenges of extinguishing electric vehicles with LiIon batteries?
The high-voltage battery in vehicles with alternative drive systems poses an increased risk of electrical accidents. The high-voltage cables are marked in orange and must not be cut under any circumstances!
The battery of the electric car is usually installed in the underbody and is therefore difficult to access, meaning that not much cooling water reaches the battery under normal conditions.
The risk with lithium-ion batteries is a so-called thermal runaway, which means that many battery cells ignite each other through chain reactions. The damage can hardly be localized in the battery.
In addition, vehicles of modern design generally have a higher fire load and burn with higher energy release and smoke development.
What methods are currently available for fighting fires in vehicles with alternative drive systems, e.g. lithium-ion batteries?
- Wet quarantine/extinguishing container
- Extinguishing lance
- Extinguishing spike
- Extinguishing blankets
- SnakE underfloor cooling
What is the recommendation of the AGBF Bund for firefighting in motor vehicles with electric drives?
Following the recommendations of the Preventive Fire and Hazard Protection Expert Committee and the Deployment, Extinguishing Agents and Environmental Protection Expert Committee of the German fire departments from the AGBG Bund, the following procedure was officially recommended in January 2021.
The initial fire-fighting measures are the same as for a normal car fire: cooling with water and, if necessary, with extinguishing agent additives such as extinguishing foam or wetting agent.
It is important to always consult the latest rescue data sheets.
In general, modern vehicles release more smoke and heat.
If it is an electric vehicle, the high-voltage battery should be examined with a thermal imaging camera.
Water remains the most efficient extinguishing agent for firefighting.
If the temperature measured when checking the high-voltage energy storage system in the electric vehicle is significantly higher than the outside temperature, in combination with a steady rise in temperature, the current recommendation is to cool the housing of the high-voltage energy storage system with water.
Quarantine is explicitly not the task of the fire department. In its latest technical recommendation, the German Social Accident Insurance (DGUV) advises that this method should only be used in absolutely exceptional cases, as the disposal of extinguishing water presents fire departments with a major logistical challenge. In particular, preventive wet quarantine should be avoided.
The HV battery in the electric car must be cooled and checked with the thermal imaging camera until the vehicle can be handed over to the operator or a suitable tow truck.
The extinguishing effect is only achieved by the cooling effect of the water.

How much water should be used when fighting fires in high-voltage storage systems in vehicles with alternative drive systems?
According to the latest recommendations of the German Statutory Accident Insurance, the procedure in the event of a road traffic accident involving a vehicle with alternative drive systems is as follows.
It is advisable to use two different pipes at an early stage, one for classic car firefighting and one for cooling the lithium-ion battery (LIB).
A small amount of water is usually sufficient for efficient cooling.
It is recommended to better reach the underbody of the vehicle with the high-voltage storage tank in order to increase efficiency and keep extinguishing water consumption as low as possible.

The individual nozzle modules are connected with specially assembled D-hoses. This ensures an optimum spray pattern at all times and SnakE can be easily extended.
The nozzle modules can be mounted on a specially dimensioned, foldable aluminum frame or on a plug-in ladder. The overall height is so low that you can still get under most standard electric vehicles even if the tires have burst.
The water is supplied via a C connection, which is split into two D outlets after a filter. This ensures that there is always a sufficient water supply and the nozzles are protected against clogging. The nozzles can atomize the water finely at any time and thus increase the cooling capacity with reduced water consumption! Each nozzle only consumes around 20 liters per minute.
SnakE can be converted into a firefighting boom with a simple extension from us. The same SnakE set can therefore equip any pump and roll-capable fire engine with a forest fire spray bar. Ideal support for vegetation fires, oil spill removal or road cleaning.
SnakE references:
Official innovation - patent pending!
SnakE combines a lithium-ion e-car extinguishing system, emergency decon shower and forest fire spray bar in one, all from a compact, standardized box.
The individual nozzle modules can be extended and replaced. The hose length ensures that the optimum distance is always set automatically.
SnakE thus offers the emergency services a small and lightweight, yet versatile and powerful tool with endless possibilities.
Cooling
The nozzles ensure very fine atomization of the water. This increases the surface area, which leads to better heat transfer and therefore increases the cooling effect. The nozzles therefore increase efficiency and a great cooling effect is achieved even with low pressure and low water consumption.
Suffocation
The fine atomization and the resulting water vapour displace the normal air and thus reduce the atmospheric oxygen. The fire lacks the oxygen for oxidation and is therefore suffocated.
Precipitate toxic fumes
The fine water droplets combine with the smoke particles and filter them out of the air. When the water mist combines with the aerosols, they are precipitated due to the increased weight.
Convinced yet?
Order now in our store! Underbody cooling?
Underbody cooling is the simplest and safest method for efficient firefighting in passenger cars with lithium-ion batteries as high-voltage storage units.
Underbody cooling avoids disposal costs and eliminates the risk of unnecessary damage to the battery.
The conductor is constantly cooled by SnakE, and temperatures are generally not as high near the ground.
As an alternative, we offer a foldable aluminum frame that can also be loaded into the EuroBox.

Introduction of SnakE
SnakE is designed in such a way that it can be slid under most standard electric car models even if the tires have burst, where it cools the underbody efficiently.
SnakE can simply be pushed under the vehicle from a safe distance using the aluminum frame or a scaling ladder.

Extinguishing agent additives
Foam concentrate and wetting agent can both be used with SnakE. The use of the correct extinguishing agent additive, e.g. with an approval for high-voltage storage systems, is the responsibility of the respective incident commander.

Normal car fire?
SnakE can also be used in a normal traffic accident involving a car fire. In an accident, the fire often starts in the engine compartment, which is difficult to reach from the outside.
Furthermore, the road surface
spared. Primarily not the job of the fire department... but who likes building sites?
Furthermore, depending on the affiliation, this also brings grateful communities...
Blockage of the nozzles
We use special nozzles with particularly clog-resistant geometry in market-leading quality.
We have also installed a redundant filter in the supply line.
Extinguish electric truck fire?
The number of electric trucks has risen sharply this year, and the trend is rising with new models.
SnakE is also suitable for firefighting on trucks with alternative drive systems. Here, the lithium-ion high-voltage battery is usually installed on the sides behind the driver's cab. However, due to the significantly higher power density of a truck, several SnakE sets should be used here.
Due to the better accessibility, the use of the extinguishing hedgehog is definitely recommended here.
SnakE can also be used for burning electric buses. In the case of electric buses, however, the high-voltage storage units are located on the roof of the vehicle.
However, the SnakE extinguishing system can be positioned accordingly due to its modularity.

Nozzle module:
The nozzle module can be attached to the uprights of a plug-in ladder or a special aluminum frame without tools.
The module can be extended on both sides.
The high-voltage battery is installed in the underbody of most vehicles.
A thermal runaway can occur in the event of an accident. This is when the individual battery modules ignite.
Supply line:
The water is supplied via a Storz C connection.
After the water has been filtered, it is fed to the modules via two D outlets.
D-hose:
The D-hoses are used to connect the individual modules and position them at the correct distances.
Stile of a scaling ladder according to DIN EN 1147
The stiles of the scaling ladder serve as the basic scaffolding.
Alternatively, the aluminum frame we offer can also be used.
C-connection:
The water is supplied via a C supply line, so the process fits in perfectly with existing extinguishing tactics.
SnakE is the smallest and lightest modular fog extinguishing system for cooling high-voltage storage systems in vehicles.
The individual nozzle modules are connected with specially dimensioned hoses. The nozzle modules are then clipped onto a plug-in ladder or a specially dimensioned foldable frame.
SnakE can now be pushed under a burning vehicle to cool the underbody in a targeted manner.
The increased efficiency enables significantly lower water consumption with the same effectiveness. This also means that less contaminated extinguishing water is released into the environment.
SnakE can even be supplied with water via a wall hydrant or household connection.
SnakE is also suitable for decontaminating or cooling gas cylinders.
Five variants + 1
SnakE forest fire set
SnakE forest fire spray bar
SnakE emergency decon - Decon level 1
An effective emergency decon shower can be set up quickly and easily with the SnakE modules and ladder components. This enables coarse cleaning of fire particles from all directions
SnakE emergency decon, where the SnakE modules are simply all connected in series and attached to a conductor support.
The emergency personnel or persons can then simply walk under the ladder frame and carry out emergency decontamination.
This reduces the risk of contamination with carcinogenic substances.
The entire system works independently of personnel, saving valuable resources that can be used more efficiently.
SnakE - Retrofit spray bars for existing vehicles
The SnakE retrofit spray bar is the upgrade for every existing pump'and'roll-capable vehicle. Simply hooked onto the shackles at the front, any fire fighting vehicle can be upgraded with the practical self-protection nozzles.
SnakE spray bars; forest fire spray bars have been known for some time, but the number of forest fires is steadily increasing and spreading to new regions.
SnakE is the first cost-effective and removable alternative for retrofitting to existing vehicles instead of having to run alongside the vehicle.
The normal SnakE nozzles are simply attached to the retrofit spray bar, creating a completely new area of application. They are attached to the shackles, towing jaw or hood.
With numerous practical tests and first customers, our SnakE multifunctional system has already proven itself and at the same time we continue to work on perfection every day.
Do we really need a new forest fire TLF?
A TLF-W looks great from the outside and hardly any fire department complains about a Unimog or Tatra.
But at over half a million euros, a new forest fire tanker is no bargain...
A modern forest fire tanker in accordance with DIN EN 1846 or based on the AGBF/DFV technical recommendation on the subject of "forest fire tankers" naturally has far more than just a spray bar and expands the range of operations considerably. But is the extra functionality just a nice-to-have or is it absolutely necessary?
Wouldn't the fire department's investment generate more benefits elsewhere?
