A fluid drainage arrangement for a battery arrangement, the fluid drainage arrangement having a fluid inlet, a collecting chamber, a membrane, a labyrinth chamber and a fluid outlet. The membrane is provided between the collecting chamber and the labyrinth chamber and has a closed state (Z1) and an open state (Z2). The membrane is designed, in the closed state (Z1), to collect a coolant, which passes into the collecting chamber via the fluid inlet, in the collecting chamber until the membrane, at a predetermined first differential pressure between a side of the membrane that is assigned to the collecting chamber and a side of the membrane that is assigned to the labyrinth chamber, transitions from the closed state (Z1) into the open state (Z2) and allows drainage of the coolant via the labyrinth chamber to the fluid outlet.

A battery system includes a battery module, a housing, a gas conveyor, and a gas sensor. The battery module is interconnected between a first system terminal and a second system terminal by a plurality of high current connectors, and the housing includes: a plurality of exterior walls enclosing the battery module and the plurality of high current connectors; and a partition wall within the housing. The gas conveyor is configured to circulate a gas flow through a flow channel loop formed within the housing by the partition wall and the exterior walls, and the gas sensor is arranged in the flow channel loop and is configured to detect an excess concentration of a gas species in the gas flow.

A battery temperature adjustment system includes: a battery configured to store electric power from an external power source, and supply electric power to a motor as a drive source of a vehicle; a cooling device to which the electric power from the external power source and the electric power from the battery are selectively supplied and configured to cool the battery; and a control device configured to control the cooling device to lower a temperature of the battery to a target cooling temperature while the vehicle is stopped. The target cooling temperature is a variable value. The control device obtains a target set by a user, and sets the target cooling temperature based on the target.

A holding apparatus (15) for current and signal conductors of a traction battery of a motor vehicle has a plate-like base body with longitudinal sides (16), transverse ends (17) and a top (18) and bottom (19) extending between the longitudinal sides (16) and transverse ends (17). Elements (20) are arranged on the top (18) and the bottom (19) for guiding and fixing current conductors (12) of the traction battery, and elements (21) are arranged on the other of the top (18) and the bottom (19) for guiding and fixing at least one signal conductor (14) of the traction battery. The base body provides EMC shielding of the signal conductor (14) from the current conductors (12). The plate-like base body has on the opposite longitudinal sides (16) and/or on the opposite transverse sides (17) sections (22) for securing and grounding the holding apparatus on a frame of the motor vehicle.
