摘要:
Battery charging device and method for charging batteries by means of a power supply module, whereby a battery (30) comprises a plurality of battery blocks (31, 32, 33, . . . , 3n) connected in series. The individual battery blocks (31, 32, 33, . . . , 3n) of the battery (30) are charged serially one after the other, once per charging cycle for a definable duration, and the charging cycle is repeated so many times until the individual battery blocks (31, 32, 33, . . . , 3n) have reached a definable state of charge or until the power supply is broken. The invention relates in particular to methods and systems for charging batteries (30) in electric vehicles, among other things.
摘要:
A line guiding assembly is provided having lines that are held together by a common line bundling apparatus. The line bundling apparatus has disposed on its outside a sliding apparatus which acts in the longitudinal direction of the lines. The sliding apparatus prevents friction between an upper length portion and a lower length portion of a line assembly.
摘要:
A process for preparing microporous separating elements for batteries by intensive mixing of a high molecular weight polyethylene with a precipitated silica having specific chemical and physical characteristics, a process liquid and a stabilizer to form a powder mixture, which is extruded to form a film, from which the process liquid is removed, thereby leaving the desired microporous separating elements which are recovered.

Precipitated silica with a sodium sulphate content of 4 to 18 wt. %, particularly with the physical-chemical data:______________________________________Sodium sulphate content: 4-14 wt. %BET surface area (DIN 66131): 100-190 m.sup.2 /gDBP absorption (anhydrous) 208-250 g/100 g(DIN 53601, ASTM D 2414): 3.0-6.5 wt. %(DIN ISO 787/II)Oversize with >63 .mu.m .ltoreq. 10.0 wt. %ALPINE air-jet sieve >150 .mu.m .ltoreq. 0.1 wt. % >250 .mu.m .ltoreq. 0.01 wt. %______________________________________It is prepared by introducing hot water into a precipitation vessel, with stirring, adding water glass, then heating the mixture and maintaining the temperature throughout the remainder of the precipitation period. Water glass and sulphuric acid are added simultaneously during this process. The precipitated silica is then separated from the suspension and the filter cake containing sodium sulphate is dried in a spray drier and ground. The precipitated silica may be used in the production of battery separators.
摘要:
The invention relates to mixtures including resorcinol and silica which are used as adhesion promoters for improving the adhesion between textile or metal strength carriers and rubber or plastics. The mixtures in accordance with the invention exhibit a sharply limited sublimation behavior with regard to the resorcin.
摘要:
An assembly for guiding cables or tubes between a stationary part and a part which follows the movements of a bidirectionally rotatable body is provided, wherein the cables or tubes are arranged in two oppositely turning loops on both sides of the axis of rotation of the body.
摘要:
A method of granulating resorcinol/silica mixtures which comprises transporting a mixture of resorcinol and precipitated silica by conveyor worms to two pressing rollers whose shafts are attached vertically above one another and whose contact pressure can be varied, compacting said mixture between said rollers, breaking up the compacted mixture with a cake breaker to obtain a granulate with minimum grain size and separating the remaining dusty portion of said mixture. The mixtures can be added to vulcanizable rubber to provide improved adhesion to rubber reinforcements.
