I01�High-voltage�battery�unit

The�technical�changes�to�the�high-voltage�battery�unit�concern�only�the�housing�and�the�cell�modules.To�accommodate�the�increased�weight�of�the�cell�modules,�the�tray�bottom�has�been�reinforced.The�cell�modules�have�not�changed�in�their�dimensions�or�in�their�design.�Only�the�capacity�of�theindividual�battery�cells�has�increased.�This�increases�the�weight�of�the�cell�modules.�The�remainingcomponents,�such�as�the�battery�management�electronics�and�safety�box,�have�not�changed.�Nor�hasthe�cooling�system�or�the�electrical�heating�changed.

4.2.�Electric�motorThe�efficiency�of�the�electrical�machine�has�been�increased�by�fitting�new�lightweight�roller�bearingswith�lower�coefficients�of�friction�on�the�i3s.

4.3.�Hill�Hold�functionThe�Hill�Hold�function�was�introduced�during�product�updating�measures�and�has�now�been�adoptedfor�the�LCI.�The�Hill�Hold�function�differs�from�the�familiar�Auto�Hold�function�in�BMW�vehicles�in�thatthe�holding�torque�required�is�generated�by�the�electrical�machine�and�not�by�the�Dynamic�StabilityControl.

The�Hill�Hold�function�allows�the�customer�to�prevent�the�vehicle�from�rolling�away�without�pressingthe�brake�pedal�after�halting�the�vehicle�on�uphill�and�downhill�gradients�of�up�to�8%.�The�Hill�Holdfunction�is�designed�to�hold�a�BMW�i3�with�REX�which�is�fully�equipped�and�at�a�maximum�weight�of3814�lbs�on�an�uphill�or�downhill�gradient�of�8%.�A�torque�of�approximately 52�lb-ft�is�required�for�this.The�torque�is�generated�in�the�electrical�machine�using�zero�speed�control.

Since�heat�or�voltages�can�influence�the�electric�drive�system,�it�is�possible�that�the�holding�torquebecomes�unavailable�over�the�course�of�time.�In�this�case,�the�holding�function�must�be�ensured�onthe�vehicle.�This�is�why�it�is�necessary�to�switch�over�to�an�alternative�holding�system�which�is�theelectronic�parking�brake.�This�is�achieved�using�a�software�function�in�the�EDME.�The�function�is�onlyswitched�to�the�electric�parking�brake�if�the�vehicle�has�exceeded�the�8%�threshold�or�the�temperatureof�the�electric�machine�is�to�high.

The�Hill�Hold�function�is�active�in�drive�positions�D�and�R�and�the�customer�does�not�need�to�activateit.

4.4.�New�traction�controlThe�BMW�i3s�has�Dynamic�Stability�Control�with�the�functions�familiar�from�other�BMW�vehicles.�Theonly�difference�is�that�the�BMW�i3�is�not�fitted�with�a�DTC�button.�DTC�is�turned�on�and�off�using�theiDrive�controller.�The�BMW�i3�had�previously�also�had�Dynamic�Traction�Control.�But�this�was�limitedonly�to�the�lower�speed�range�up�to�30�mph�and�essentially�designed�for�straight-ahead�driving.

The�DTC�function�was�also�modified�when�the�new�cruise�control�function�was�introduced�in�the�BMWi3s�for�11/2017.�This�means�that�maximum�traction�is�available�in�the�speed�range�over�60�mph�andmore�drive�power�is�permitted�even�when�cornering.

Special�Automatic�Stability�Control�has�been�developed�for�the�demands�of�a�highly�dynamic�electricdrive.�The�control�cycle�works�noticeably�quicker�than�the�previous�ASC�system.�The�ASC�systemalso�operates�during�recuperative�deceleration�of�the�vehicle�and�ensues�that�the�deceleration�can�bemaintained,�even�given�difficult�road�surface�conditions�(rain/snow),�and�hence�more�energy�can�berecuperated.�This�results�in�improved�stability,�traction�and�availability�of�energy�recovery�in�all�drivingand�ambient�conditions.�In�addition,�an�expanded�and�redesigned�DTC�mode�ensures�enhancedtraction,�particularly�on�loose�surfaces�and�even�more�driving�pleasure�over�the�full�speed�range.

8.5.�Driving�dynamics�controlThe�BMW�i3s�has�Dynamic�Stability�Control�with�the�functions�familiar�from�other�BMW�vehicles.�Theonly�difference�is�that�the�BMW�i3�is�not�fitted�with�a�DTC�button,�however�it�can�be�turned�on�and�offvia�the�iDrive.�The�BMW�i3�had�previously�also�had�Dynamic�Traction�Control�.�But�this�was�limited�onlyto�the�lower�speed�range�up�to�30�mph�and�essentially�designed�for�straight-ahead�driving.

The�DTC�function�was�also�modified�when�the�new�cruise�control�function�was�introduced�in�the�BMWi3s�for�11/2017.�This�means�that�maximum�traction�is�available�in�the�speed�range�over�60�mph�andmore�drive�power�is�permitted�even�when�cornering.

Special�Automatic�Stability�Control�has�been�developed�for�the�demands�of�a�highly�dynamic�electricdrive.�The�control�cycle�works�noticeably�quicker�than�the�previous�ASC�system.�The�ASC�systemalso�operates�during�recuperative�deceleration�of�the�vehicle�and�ensues�that�the�deceleration�can�bemaintained,�even�given�difficult�road�surface�conditions�(rain/snow)�and�hence�more�energy�can�berecuperated.�This�results�in�improved�stability,�traction�and�availability�of�energy�recovery�in�all�drivingand�ambient�conditions.�In�addition,�an�expanded�and�reconfigured�DTC�mode�ensures�enhancedtraction,�particularly�on�loose�surfaces�and�even�more�motoring�pleasure�over�the�full�speed�range.�Theoutstanding�drivability�under�acceleration�and�recuperation�under�all�ambient�conditions�enhancessafety�and�ride�comfort.
