Definitions

  • the present invention relates to the field of support benches or trolleys for the maintenance of a vehicle propulsion battery.
  • Battery packs used to propel electric vehicles store large amounts of energy in a small space, defining high energy densities.
  • Individual cells or groups of cells can be equipped with devices that try to limit or avoid the effects of anomalous situations that can compromise safety.
  • a typical phenomenon considered anomalous is the so-called thermal runaway. Phenomenon in which a large amount of heat and gases are developed that can lead to the ignition of a fire.
  • Such conditions can be caused by the failure of a battery cell, thermal or mechanical abuse or the short circuit of at least one of the cells of the battery pack.
  • the heat released by the short circuit can be quite large, depending on many factors, including the amount of energy converted into heat and the location of the short circuit, can start a chain reaction.
  • a predetermined threshold which is approximately 200°C in relation to the electro-chemical characteristics of the cell
  • an irreversible exothermic chain reaction is triggered which causes the overheating and failure of the cells adjacent to the one initially damaged, releasing heat which, in turn, spreads to the entire battery pack.
  • a fire may start or, in extreme cases, the entire battery pack may explode.
  • the related control and monitoring systems are not able to signal the triggering of a thermal drift with serious risk for maintenance workers who are preparing to disassemble the battery pack.
  • the purpose of the present invention is to make maintenance operations conducted on a vehicle battery pack safer.
  • the basic idea of the present invention is to propose a support bench or trolley for the maintenance of a vehicle propulsion battery comprising a work surface and an underlying container volume capable of containing a coolant/extinguishing liquid, wherein the work surface is capable of releasing or accompanying a battery supports into the container volume in response to a detection of a dangerous condition.
  • the dangerous situation can be determined by the operator and therefore the trolley comprises at least one human/machine interface device arranged to activate the immersion of the vehicle battery subject to maintenance.
  • the dangerous situation can be determined by a special detection system configured to automatically activate the immersion of the vehicle battery being maintained.
  • battery pack and “battery” have the same meaning, meaning a set of cells packed inside a casing which may include electrical and electronic circuitry known in itself.
  • the container volume of the trolley contains the coolant/extinguishing liquid before the vehicle battery is placed on the relative support surface for maintenance.
  • the container volume of the trolley is empty, the trolley includes hydraulic means for connection to a coolant/extinguishing liquid pipeline and means are present for activating the filling of the container volume of the trolley. More preferably, the trolley includes means for automatically activating the filling of the container volume in response to the introduction of the battery inside the container volume.
  • FIGs. 1 - 3 some variants of the present invention are shown.
  • Fig. 1 shows a support bench T comprising a work surface P and an operationally underlying, lower-closed container volume V, capable of containing a liquid, in particular an extinguishing and/or refrigerant liquid.
  • the lower-closed volume is defined by an operationally horizontal back wall BW and by perimeter and operationally vertical walls LW.
  • the support bench preferably has a parallelepiped shape, but could have different shapes depending on the circumstances.
  • the work surface P is positioned at an ergonomic height between 90 and 110 cm as required by OHSAS 18001.
  • the work surface is arranged to release, for example by rotating with respect to an edge hinged to a wall of the container volume, or to accompany the battery, by means of a translation.
  • At least a portion of the work surface P is arranged to assume
  • the work surface P is slidably associated with at least two perimeter and vertical walls LW by means of guides G, arranged to allow a transition between the first and second positions of the support surface, by translation.
  • wheels R are rotatably fixed to the work surface P and are slidably associated with the vertical guides G, arranged on the internal faces of the perimeter and vertical walls LW to guide the support surface P during the stroke from the first to the second position and vice versa.
  • Locking means UL are arranged to lock the work surface P in the first position.
  • the locking devices can be manually and/or electrically released, for example, by means of an electric lock.
  • the container volume closed at the bottom, includes hydraulic connection means PC which include for example a first manual valve V1, arranged externally to the container volume, and preferably quick coupling means for connection to a conduit connected to a source of refrigerant and/or extinguishing liquid L.
  • hydraulic connection means PC which include for example a first manual valve V1, arranged externally to the container volume, and preferably quick coupling means for connection to a conduit connected to a source of refrigerant and/or extinguishing liquid L.
  • a further preferred variant of the invention is shown, according to which the filling of the container volume V is performed automatically in response to the introduction of the load, i.e. the battery B, inside the same container volume.
  • the hydraulic connection means comprise a second normally open valve V2 and a normally closed valve V3 in cascade to the second valve; both arranged inside the container volume.
  • the battery When the battery is introduced into the container volume V, directly or indirectly, it acts on a lever operationally connected to the third normally closed valve V3 causing the opening of the third valve and therefore the flooding of the container volume V.
  • the normally open valve V2 is associated with a float arranged in the container volume. When the extinguishing and/or refrigerant liquid L reaches a predetermined level, then the float closes the second valve V2.
  • the filling of the container volume V is completely automated.
  • the blocking means UL are electro-actuated and interlocked with a monitoring system.
  • monitoring is performed 24 hours a day, without the presence of a human operator and furthermore, the immersion of the battery in the liquid is performed completely automatically with greater safety not only for people but also for the working environment.
  • the support bench is equipped with wheels W fixed under the back wall BW to allow easy movement of the same even in the presence of liquid inside, defining a trolley.
  • the device T When the device T is equipped with wheels W, then it defines a trolley.
  • This trolley can be equipped with handles (not shown) to facilitate its grip and movement. Implementation variants to the non-limiting example described are possible, without however departing from the scope of protection of the present invention, including all the equivalent embodiments for a technician in the field, to the content of the claims.
