Battery penetration device for fighting fires in electric vehicle
Fire risk management related to electric vehicle.
An electric vehicle battery, EVB, also known as a traction battery, is a re- chargeable battery used to power the electric motors of a battery electric vehicle or hybrid electric vehicle. Different types of batteries may be used, but typically lithium- ion batteries are used. Lithium-ion batteries are specifically designed for high electric charge or energy capacity.
With the transition to electric transportation comes new challenges. Vehicles with lithium-ion batteries can be especially dangerous when they catch fire and very difficult to fight. When fires do occur, electric vehicles with lithium-ion batteries burn hotter, faster and require far more water to reach final extinguishment. A know fire hazard is that the batteries can reignite hours or even days after the fire is initially controlled, leaving salvage yards, repair shops and others at risk.
During a fire, over 100 chemicals are generated from the battery, including toxic gases such as carbon monoxide and hydrogen cyanide, which are fatal to hu- mans. If the battery is exposed to excessive heat, or there is a penetration due to a de- fect in the battery case, an internal short circuit may occur. The short circuit causes excessive heat, which in turn causes a chemical reaction that generates more heat.
The excessive heat makes the chemical reaction to develop even faster, which results in more heat etc. This process is called “thermal runaway” and is a primary reason for generating fires in electrical vehicles. The fires are difficult, dangerous and time con- suming to fight.
Heat and electricity are a huge hazard for the firefighters. It is well known that problems with fire in an electric vehicle is that when extinguishing it, there are not only considerable dangers from the fire, but also from possible self-igniting elements, such as lithium-ion batteries, and additional dangers from spreading high voltages.
DK 181580 B1 2
The document WO2021/224457 describes an extinguishing lance for fighting fires in electrically charged objects, such as vehicles equipped with an electric motor and battery. The extinguishing lance has a holding section with a handle part for an operator. An extinguishing agent feed with a coupling device for connecting a pressure hose for liquid extinguishing agent, and one attached to the holding section. The prob- lem using a lance is that the tip of the lance must be forced into a battery by means of hammering. This may be very difficult for the firefighters to provide the force needed to penetrate the battery, due to lack of space, movement limitation due to the firefight- ers clothing, or due to the high temperature during operation because the process takes tolong. This increases the potential fire hazard for the firefighters. Only the handle part of the holding section having a voltage-insulating coating, which is designed to be elec- trically insulating for electrical voltages. The problem that the firefighters must be very careful, when penetrating a battery with an extinguishing lance, because the firefighters is limited in holding the extinguishing lance firmly and safely, while forcing the tip of the extinguishing lance into the battery. A firefighting operation present a considerable potential risk for the firefighters of being injured during the procedure when using an extinguishing lance.
The object of the invention is to provide a device to reduce temperature in a battery pack installed in an electrical vehicle, such that a fire can be extinguished more rapidly and subsequent fire harzard can be reduced.
The present invention addresses this by providing a battery penetration device for reducing temperature in at least one battery in a battery pack, wherein the battery penetration device comprises a tube having an inlet for fluid, and a nail is arranged in a first end of said tube, wherein the nail is configured to enter said battery pack, wherein the nail has at least one fluid outlet, wherein said fluid inlet is in fluid communication with said fluid outlet, such that fluid is capable of entering said battery pack and thereby reducing a temperature inside the battery pack when cooling the battery pack with said fluid.
DK 181580 B1 3
The battery penetration device fighting fires or potential fire hazard in battery packs, which is installed in electric vehicles. One way to extinguish fire or reduce temperature in a battery pack is to flood the battery pack with cold fluid. The battery pack can be flooded using fluid, such that a fire inside battery pack can be extin- guished. Due to the cooling process the temperature inside the battery pack can be re- duced and be kept at a low temperature. This process reduces the risk of fire and keeping the damage situation under control.
The battery penetration device is capable of reducing temperature in at least one battery pack, while the battery is installed inside an electric vehicle. The battery penetration device comprises a tube having an inlet for fluid. The fluid inlet may be provided in a position along the tube. A fluid source may be attached to the fluid in- let. A nail is arranged in a first end of the tube. The nail is configured to enter the bat- tery pack. The nail is configured to enter the battery pack, for example by using oper- ating means to force the nail into the battery pack. The nail has at least one fluid out- let. The fluid inlet is in fluid communication with the fluid outlet. When the nail is in- serted into the battery pack, the fluid can enter the battery pack through the fluid out- let in the nail.
A fire in electric vehicle may reignite minutes, hours, or even days after the initial event. This causes a latent fire hazard. One of the reasons for reignition may be thermal runaway in a battery inside the battery pack. If the temperature in the battery is remained at a low temperature due to a cooling process, the cooling process will prevent thermal runaway. This will reduce the fire hazard significantly. The continu- ous flow of fluid thereby reduces the temperature inside the battery pack, when cool- ing the battery with the fluid and thereby prevents an uncontrolled thermal runaway.
The fire can then be extinguished more rapidly, and subsequent fire hazard can be re- duced and controlled more easily.
With the use of the battery penetration device, the cooling process will be faster and more efficient to prevent or reduce a fire from speeding inside an electric vehicle. The amount of water required, and the amount of harmful smoke and gases
DK 181580 B1 4 released is reduced during the cooling process, because the cooling is directly related to the batteries inside the battery pack.
In an advantageous embodiment of the invention, said tube comprises material having insulating property, such that the tube is electrical insulated from the battery pack, when said nail is entering said battery pack.
A common battery pack in electric vehicle may for example comprise blocks of 18-30 parallel cells or more in series to achieve a desired voltage. For example, a 400V nominal battery pack may have around 100 series blocks. The voltage may even be higher that 400V. These higher voltages allow more power to be transferred to the bat- tery pack with less loss over the same diameter, due to the relationship between current vs resistance in the cables. The cells and blocks may be connected in many different electrical connection patterns, dependent of the manufactory of the battery pack.
To prevent a discharge of batteries through the battery penetration device, when entering the battery pack, the tube is electrically insolated, and thereby preventing an electrical path from the batteries to the ground through the battery penetration device.
To ensure that the electricity does not damage the battery penetration device or injure a fire fighter when using the battery penetration device, the material of the tube has electrical insulating property. The nail is prevented to have an electrical communication with the opposite end of the battery penetration device. Furthermore, the material of the tube may also comprise thermal insulating property, which also may protect the battery penetration device from the high temperature during firefighting, and also pro- tect the firefighter when using the device during firefighting.
In a further advantageous embodiment of the invention, an operating member is arranged relative to a second end of said tube.
The nail of the battery penetration device may be forced inside the battery pack, such that the fluid is capable of entering the battery pack. An operating member is arranged in a second end of the tube opposite the end of the nail. An operating means
DK 181580 B1 may be an operating device, which may be capable of hammering or rotating the nail, such that the nail may be forced through any part of an electric vehicle and part of the nail may be forced inside the battery pack. The operating member is arranged, such that the battery penetration device may be operated by a firefighter, robot or others using 5 an operating device.
In a still further advantageous embodiment of the invention, said nail is a drill unit.
The battery penetration device may comprise a drill unit. The drill unit is a cutting tool used to create holes, and at the same time having a fluid outlet which is capable of providing a continuous flow of fluid. Fire fighters may easily penetrate the battery inside an electric vehicle using the battery penetration device operated with an operating device. The operating device may be a drilling device. The drilling device may be connected to the operating member, which is arranged relative to the second end of said tube. The drill unit may be arranged relative to the first end of the tube.
The operating member or part of the operating member may be connected to the drill unit, such that when rotating the operating member causes the drill unit to rotate.
The drilling unit comprises at least one spiral shaped recess. The spiral shaped recess may also be used as fluid outlet. The fluid from the fluid outlet may cool the drill unit, while drilling through the battery pack. The fluid from the fluid outlet may reduce the temperature inside the battery when the drill unit has entered the battery pack.
In a further advantageous embodiment of the invention, said battery penetration device comprises a rotatable inner tube arranged inside said tube.
The battery penetration device comprises a rotatable inner tube. The rotata- ble inner tube may extent from the first end to the second end of the tube. In one end the rotatable inner tube extends towards the nail. In the opposite end of the nail the rotatable inner tube extends towards an operating member. The rotatable inner tube
DK 181580 B1 6 rotation causes the nail to rotate, such that the rotatable inner tube and the nail have a corresponding rotation.
The operating member or part of the operating member may be connected to the drill unit using a rotatable inner tube arranged inside the tube, such that when ro- tating the operating member causes said rotatable inner tube to rotate the drill unit.
The operating member may comprise moveable means, such that said operating mem- ber is capable of rotating the drilling unit using said rotating member inside the tube using the moveable means.
In a still further advantageous embodiment of the invention, said rotatable inner tube comprises insulating property, such that the operating member is electrically in- sulated from the drill unit.
To ensure that the electricity does not damage the battery penetration device or injure a fire fighter when using the battery penetration device, the material of the tube has electrical insulating property. The rotating member may comprise electrical insulating property, such that the operating member is electrically insulated from the drill unit. The rotating member may comprise thermal insulating property, such that the operating member is thermal insulated from the drill unit.
The material used may be fiber reinforced plastic, also called fiber reinforced polymer. The fiber reinforced plastic is a composite material made of a polymer matrix reinforced with fibers. The fibers are usually glass, as in fiber glass, carbon, as in carbon fiber reinforced polymer, aramid, or basalt. Rarely, other fibers such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins may be used.

The first end of the tube is attachable in a second end of the exten- sion member. The shape of the extension member or part of the extension member may be substantially cylindric having a longitudinal direction.
Because the cells and blocks may be connected in many different electrical connection patterns, dependent of the manufacturer of the battery pack and the arrange- ment of the battery pack in the electric vehicle, the need for different length may be required. The extension member may be interchangeable, such that a suitable length of the extension member may be chosen for the task. The length of the extension member may be related to the type of electric vehicle and the placement of the battery inside the electric vehicle. The extension member may easily be replaced with another extension member.
The extension member has at least one fluid conduit. The fluid conduit is ar- ranged inside the extension member in the longitudinal direction. The tube is in fluid communication with the nail through the fluid conduit inside the extension member.
