Definitions
- the invention relates to a motor vehicle battery with a cover according to the preamble of claim 1, as is known from the unpublished DE 101 61 566.
- Motor vehicle batteries are usually installed in a water box closed with a plastic cover, a removable plastic part being provided in the plastic cover for access to the motor vehicle battery.
- the problem with such motor vehicle batteries is the electrostatic charging of the plastic cover, since the high voltage built up as a result of the electrostatic charging can be discharged in the direction of the negative pole of the motor vehicle battery. Particularly in the event of minor leaks in the motor vehicle battery, this discharge can take place inside the motor vehicle battery within the gas space located above the battery fluid, which can lead to an explosion of the motor vehicle battery.
- the cover of the motor vehicle battery in the generic DE 101 61 566 is designed to be electrically conductive and is connected directly to the negative pole of the motor vehicle battery.
- connection can be realized either by an insulating cable arranged between the negative pole of the motor vehicle battery and the cover or by a contact spring which is captively attached to the negative pole of the motor vehicle battery and makes electrical contact with the cover.
- the invention has for its object to provide a motor vehicle battery in which protection against the consequences of electrostatic charging is made possible in a simple and inexpensive manner. This object is achieved by the features in the characterizing part of patent claim 1.
- an electrically conductive contacting element is provided on the underside thereof for the force-locking contacting of the negative pole of the motor vehicle battery, ie the electrically conductive contacting element fastened to the cover of the motor vehicle battery is used for the non-positive, electrically conductive connection of the cover to the negative pole of the motor vehicle battery.
- This electrically conductive contacting element can be designed as a spring-loaded contact tab protruding from the underside of the cover, which, as a result of the spring force, presses against the negative pole of the motor vehicle battery and preferably consists of the same material as the electrically conductive cover (for example, the contact tab is stamped out of the cover or formed by an injection molding process), or as a contacting screw formed on the underside of the cover and projecting from the underside of the cover, which is connected to the negative pole of the motor vehicle battery by pressing on it with a specific pretension or by screwing it to its pole terminal.
- the electrically conductive cover of the motor vehicle battery can consist of metal or of electrically conductive plastic or of an electrically insulating plastic that is at least partially coated with an electrically conductive coating (for example with a glued-on metal foil or with a metallization or with an electrically conductive lacquer layer). or with an electrically conductive insert (e.g. with a contact tion of the negative pole of the motor vehicle battery partially exposed metal network) is provided.
- the cover lies on the battery cover formed on the top of the motor vehicle battery, in particular the cover lies on the outer contour of the battery cover (i.e. on the protrusion of the battery cover located there) with a slight play.
- a cover can be provided for motor vehicle batteries with different capacities and in particular different dimensions (different sizes) of the battery cover of the motor vehicle battery, for example. a cover made with a specific dimension, this cover can be adapted by subdivision to the respective dimension of the battery cover of the motor vehicle battery.
- the area of the positive pole of the motor vehicle battery is not covered by the cover, in particular a recess in the cover is provided on the battery cover in the area of the positive pole of the motor vehicle battery.
- the cover is connected to the battery cover in a form-fitting or non-positive manner by means of fastening means arranged on its outside (side surface), in particular by means of fastening clips. by means of fastening clips attached on the long side of the cover and engaging on the underside of the battery cover.
- At least one rib is formed on the underside of the cover in the region of the electrically conductive contacting element, which rib serves as a stop when the cover is attached (put on or pushed on) to the battery cover of the motor vehicle battery.
- FIG. 1 shows a plan view of the motor vehicle battery installed in the motor vehicle
- FIG. 2 shows a sectional drawing of a partial area of the motor vehicle battery.
- the motor vehicle battery 1 is, for example. arranged in the trunk of the motor vehicle below the trunk cover.
- An electrically conductive cover 2 lies flush on the battery cover 7 forming the upper side of the motor vehicle battery 1.
- This electrically conductive cover 2 is, for example. made of a warm air-resistant, electrically conductive plastic, e.g. made of chlorinated polypropylene (PPC) with an electrical conductivity in the range from 10 3 to 10 5 ⁇ "1 and is, for example, manufactured as an injection molded part.
- PPC chlorinated polypropylene
- the cover 2 can be used for motor vehicle batteries 1 with different capacities and thus different dimensions (width of the motor vehicle battery 1 e.g.
- the cover 2 for example made as an injection molded part, can be subdivided at the dividing line 15 and the cover 2 can thus be individually adapted to the respective motor vehicle battery 1 a cover 2 with the dimensions length 347 mm, width 181 mm and thickness 1.5 mm in the longitudinal direction 12 of the cover 2 a dividing line 15 at 273 mm, so that a further, smaller cover 2 with the dimensions length 273 mm, width 181 mm and Thickness 1.5 mm can be manufactured
- the cover 2 with the length of 347 mm is used, for example, for motor vehicle batteries 1 with a capacity of 95 Ah or 110 Ah, with almost the entire battery cover 7, with the exception of the positive pole 14 of the motor vehicle battery 1, being covered by the cover 2.
- the cover 2 with the length of 273 mm is, for example. used for motor vehicle batteries 1 with a capacity of 70 Ah or 80 Ah, with approximately the entire battery cover 7, with the exception of the positive pole 14 of the motor vehicle battery
- an example is on the underside 4. formed as an injection molded part from the electrically conductive plastic of the cover 2 contact tab 5, which presses the cover 2 on the battery cover 7 due to the elastic spring force non-positively against the negative pole 3 of the motor vehicle battery 1 and thus electrically conductively connects it to the electrically conductive cover 2 ,
- Fastening means 10 designed as fastening clips are provided, for example.
- two fastening clips 10 which clamp the battery cover 7 on the underside 11 of the battery cover 7.
- a rib 13 is formed on the underside 4 of the cover 2 in the area of the contacting tab 5 and is used to adjust the cover 2 with respect to the longitudinal direction 12 of the motor vehicle battery 1.
- this rib 13 acts as a stop and thereby ensures that the contacting tab 5 is positioned as desired in the region of the negative pole 3 of the motor vehicle battery 1 and thereby the negative pole 3 of the motor vehicle battery 1 contacted reliably and thus reliably discharges any electrostatic charges to ground.
