摘要： Various embodiments disclosed herein relate to systems and methods for battery cell ventilation. A corrugated battery module lid may be integrated above a battery cell module, wherein the corrugated lid includes a plurality of crests and troughs to form one or more gas emission channels. The plurality of crests and troughs may be at least partially positioned to encompass at least one of the plurality of battery cells to form enclosures. The enclosures may accumulate a maximum amount of gas pressure from a gas emitted by the at least one of the plurality of battery cells. One or more pressure release mechanisms may be associated with the plurality of enclosures and integrated with the battery module lid. In response to the enclosure exceeding the maximum amount of gas pressure, the gas may be automatically released through the pressure release mechanisms and flow though the channels between the crests.

摘要： The present invention relates to a drive shaft arrangement (27, 127) for an all-wheel drive electric vehicle (1), comprising a drive shaft (23) arranged to transfer torque a drive shaft joint (32, 132) at least partially enclosing a drive shaft end portion (23a, 123a), wherein the drive shaft joint (32) comprises a housing (31, 131) and a one-way clutch (41a, 141a) provided at an inner portion (33, 133) of said housing (31, 131). The one-way clutch (41a, 141a) being arranged within said inner portion (33, 133) to engage with said drive shaft (23) at a first drive shaft state, in which the drive shaft (23) transfers torque from said drive shaft (23) in a first direction; disengage from said drive shaft (23) at a second drive shaft state, in which the drive shaft (23) is idle or transfers torque in a second direction opposite to the first direction. The present invention also relates to a vehicle (1) comprising said drive shaft arrangement (27, 127).
