Overview of System ComponentsThe power supply system of the E70 consists of the following components: Vehicle battery Distribution box on the battery Rear distribution box on the right-hand side of the luggage compartment Battery cables Front distribution box behind the glove compartment Junction box control unit E-box engine compartment Jump start connection point Alternator.The most important new features/changes to the power supply system in the E70 aredescribed belowVehicle BatteryThe vehicle battery is installed on the rear right in the luggage compartment floor.The vehicle batteries are 70 Ah and 90 Ah batteries. Depending on the equipment,these batteries are AGM (Absorbent Glass Mat) batteries. The main advantage of theAGM battery is its higher cycle strength.Distribution Box (on battery)The distribution box in the luggage compartment of the E70 is mounted directly on thevehicle battery. The rear distribution box on the battery is secured on the vehicle batteryby means of a metal tab. The metal tabs must be pressed downward and outward inorder to release the distribution box.The distribution box on the battery is equipped with fuses for the following electric loads: Electrical auxiliary heater (100 A) Valvetronic or common rail system (80 A) Intelligent battery sensor IBS Reserve Front distribution box (250 A) Rear distribution box (100 A) Large electric fan 850 W (100 A) Reserve.8E70 Voltage Supply and Bus Systems
The distribution box on the battery should be replaced only as a complete unit.The fuses are integrated as a complete unit in the housing of the distribution box on thebattery. The fuses differ in terms of their power rating. The distribution box additionallycontains the power supply for the IBS.IndexExplanation1Battery cable to engine2Distribution box on battery3Intelligent Battery Sensor (IBS)Note: The connectors are color-coded and mechanically coded to avoid confusion. These are high power connections, therefore always ensure correct contacting!When replacing or working on the distribution box, always make sure theplug connections and, above all, that the screw connections are securedproperly. Connection between battery terminal and distribution box- 15 Nm.IndexExplanation1Retaining clip2Connection to battery terminal3Rear distribution box connector4High current consumer connections9E70 Voltage Supply and Bus Systems
Rear Distribution BoxDue to the high number of consumers and control units in the E70, another fuse carrierhas been mounted in the luggage compartment.In addition to the fuse carrier, relays are also plugged in or soldered onto the board.The following relays are accommodated in the fuse carrier:IndexExplanationIndexExplanation1Terminal 30g relay2Plug connector10E70 Voltage Supply and Bus Systems

In the event of anerror, the entire distribution box must be replaced.IndexExplanationIndexExplanation1Terminal 30 g f relay3Terminal 15 relay2SCA relay11E70 Voltage Supply and Bus Systems
Battery CablesOn the E70, two main power leads run along the underbody from the battery box to theengine compartment. One of the main power leads is routed via the jump start terminalto the starter and to the alternator.The other cable supplies the engine electronics with power. Depending on the model ofvehicle, different line cross sections are used.CableCross sectionMaterialCable to starter and alternator on N62 engine110 mm2AluminumCable to starter and alternator on N52 engine90 mm2AluminumCable to front distribution box behind glove box35 mm2CopperCable to the motor electronics10 mm2CopperCable to electric fan 850 W12 mm2CopperOne battery cable is installed in the vehicle interior. It runs to the front distribution box.The transfer points (magnified view) for the two main power cables is located in thebattery box. To avoid damage, the main power cables are installed in a protected areaon the underbody.12E70 Voltage Supply and Bus Systems
Front Distribution BoxThis section describes the front distribution box. The junction box control unit isdescribed in the section "Junction box control unit".There are three versions of front distribution box for the E70. In the lower part of the frontdistribution box, there is an opening through which it is connected to the junction boxcontrol unit.Installation PositionThe distribution box is installed under the instrument panel on the right-hand side.To change a fuse, the distribution box must be lowered.13E70 Voltage Supply and Bus Systems
Front Distribution Box and Junction Box Control UnitThe connection between the front distribution box and the junction box control unit isrealized via the opening in the bottom of the distribution box. An internal plug connectionprovides the electrical connection between the two components.When assembled, the two components from one unit consisting of the junction boxcontrol unit and the front distribution box.Note: The distribution box and junction box control unit components are to bereplaced individually. In addition to the corresponding test modules inthe diagnostics, diagnosis cables are also available with which electricalmeasurements can be made directly on the control-unit plugs and on theinternal interface.14E70 Voltage Supply and Bus Systems
Internal Plug ConnectionThe internal plug connection is on the left inside the opening for the junction boxcontrol unit.The internal plug connection is responsible for actuating the relay in the front distributionbox. In addition, the correct operation of this relay is monitored by the junction boxcontrol unit.IndexExplanationIndexExplanation1Monitoring connection2Actuation connection15E70 Voltage Supply and Bus Systems

In the event of afault, the entire distribution box must be replaced.IndexExplanationIndexExplanation1Terminal 30g relay4Relay for wiper stage 22Heated rear window relay5Terminal 87 relay3Horn and headlight cleaning system double relay17E70 Voltage Supply and Bus Systems
Direct ContactingOn the distribution boxes, direct contacting to the fuses is carried out. The fuses areplugged into the PCB with a connection in the plug connector. The other plug connectoris connected directly with the connectors on the wiring harness.The advantages of this design modification are: Improved package space utilization Improved heat dissipationIndexExplanationIndexExplanation1Front distribution box housing3Wiring harness connector2FuseNote: Particular care must be taken to ensure that the fuses are fitted firmlywhen unplugging and re-connecting the connectors for the wiring harness. The fuses must be braced when plugging in the wiring harness.18E70 Voltage Supply and Bus Systems

E70 Overall NetworkThe overall network in the E70 consists of various bus systems that enable communication between the individual control units. In view of the increasing interconnection of thecontrol units, it is possible to use the sensors of one system throughout the network.The sensors are connected to the control unit that initially requires the informationlogic-based and virtually in real time. This information, however, can also be madeavailable to other control units.Using the example of the vertical dynamics management (VDM), initially, the VDM controlunit acquires the ride-height levels of the wheels. The dynamic headlight-rangeadjustment facility can also use this information for the purpose of adapting the beamheight of the headlights. The VDM makes available the information via the correspondingbus systems to the footwell module.Apart from the FlexRay and the D-CAN, all bus systems in the E70 are already knownfrom other BMW models. This section outlines all bus systems in the E70.This bus system is used for the first time for the data exchange in the area of the verticaldynamics management (VDM). It is used to exchange data between the VDM controlunit and the EDC satellites.Overvi
