Removal & Installation

DANGER:

Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of electric shock, electric leakage, or similar accidents if the high voltage component and Nissan Ariya vehicle are handled incorrectly. Be sure to follow the correct work procedures when performing inspection and maintenance.

WARNING:

  • Be sure to remove the service plug in order to shut off the high voltage circuits before performing inspection or maintenance of high voltage system harnesses and parts.

  • Be sure to put the removed service plug in pocket and carry it or store it in a tool box or other container so that another person does not accidentally connect it while work is in progress.

  • Be sure to put on insulating protective gear before beginning work on the high voltage system.

  • Clearly identify the persons responsible for high voltage work and ensure that other persons do not touch the Nissan Ariya vehicle. When not working, cover high voltage components with an anti-static cover sheet or similar item to prevent contact with other persons. Refer to HIGH VOLTAGE PRECAUTIONS : Precautions.

  • If the battery pack is to be disassembled, be sure to remove the Li-ion battery controller for preventing electric shock, fire, and damage to parts.

CAUTION:

There is the possibility of a malfunction occurring if the vehicle is changed to READY status while the service plug is removed. Therefore do not change the Nissan Ariya vehicle to READY status unless instructed to do so in the Service Manual.

ENVIRONMENT FOR LI-ION BATTERY DISASSEMBLY WORK

Must be an indoor environment.

  • The environment must utilize a shutter or other means to shut out the outside environment and prevent rain, snow, dust, or other substances from entering.

  • The environment must not cause the intrusion of sweat during work, or cause condensation to occur due to high temperature or humidity.

Metal powder, grease, and other foreign substances must not enter.

  • The indoor environment must also prevent metal powder, grease, and other foreign substances from entering due to maintenance performed on other Nissan Ariya vehicles and other sources during disassembly work.

  • During disassembly without internal work, temporarily close the battery pack upper case or cover it with an insulating cover.

The floor must be dry.

  • The floor must not be wet as a result of factors such as Nissan Ariya vehicle entry during rain or snow.

Work space

Be sure to follow the correct work procedures when performing inspection and maintenance.

WARNING:

  • Be sure to remove the service plug in order to shut off the high voltage circuits before performing inspection or maintenance of high voltage system harnesses and parts.

  • Be sure to put the removed service plug in pocket and carry it or store it in a tool box or other container so that another person does not accidentally connect it while work is in progress.

  • Be sure to put on insulating protective gear before beginning work on the high voltage system.

  • Clearly identify the persons responsible for high voltage work and ensure that other persons do not touch the Nissan Ariya vehicle. When not working, cover high voltage components with an anti-static cover sheet or similar item to prevent contact with other persons. Refer to HIGH VOLTAGE PRECAUTIONS : Precautions.

  • If the battery pack is to be disassembled, be sure to remove the Li-ion battery controller for preventing electric shock, fire, and damage to parts.

To prevent electric shock, wear insulated protective gear.

CAUTION:

  • If too much load is applied, the shock when it comes off is large. so carefully apply the load.

  • Battery pack is not lifted up by the load.

NOTE:

  • lifting load must be within 100 kgf approximately.

  • The figure shows module No. 14 (MD14).

Pry resin scraper (service parts: 299A3 5MP0A) left and right to peel the adhesion of gap filler.

WARNING:

  • To prevent electric shock, wear insulated protective gear and use insulated tools.

  • Do not use metal bar, etc., it may cause electric shock, damage to floor surface due to battery pack, damage to module, and liquid leakage.

CAUTION:

  • Insert one with the thicker tip of resin scraper (service part: 299A3 5MP0A) (B) between the module end plate .

  • Never pry except module end plate to prevent module from damaging, deforming and leaking liquid.

  • Never remove 2 modules or more to prevent battery pack from weight unbalance except replacement work of battery pack lower case.

NOTE:

  • Modules are in close contact with gap filler applied to battery pack lower case.

  • It can be peeled off from gap filler by sliding module sideways.

  • Since adhesive strength of gap filler is weakened, the part that was peeled off once is not re-bonded.

Remove module bolt that was temporarily installed to terminal side.

NOTE:

When module is lifted up, load the module on battery pack lower case by lowering mobile floor crane

Hang carabiners (service part: 299A3 5MP0A) in the lifting holes and install belt slinger.

WARNING:

To prevent electric shock, wear insulated protective gear.

NOTE:

Carabiners (service part: 299A3 5MP0A) are packed with new module.

Remove module from battery lower case by lifting up 4 points of module with mobile floor crane (A).

WARNING:

To prevent electric shock, wear insulated protective gear.

Peel off gap filler from battery pack lower case.

WARNING:

To prevent electric shock, wear insulated protective gear.

NOTE:

  • Gap filler can be peeled off with hands.

  • If it is not peeled off with hands, use resin scraper without damaging battery lower case.

ASSEMBLY

Note the following items, and assemble in the reverse order of disassembly.

DANGER:
  • There is the danger of electric shock caused by contact with the terminals. Be sure to wear insulated protective gear and use insulated tools.

  • Because there is a danger of electric shock and fire, never allow bus bar to contact a wrong terminal.

    • If bus bar contacts a wrong terminal, the circuit becomes energized and a short may occur.

    • Always keep the bus bar cover closed until immediately before the installation of bus bar.

Check battery pack lower case inside for foreign material or peeled gap filler

Set gauge template sheet to battery pack lower case as shown in the figure and then write lines on battery pack lower case with oil-based pen.

CAUTION:

  • Use a pen that does not have a thickness like paint.

  • Place gauge template sheet in close contact with module mounting bracket and center it.

NOTE:

Size of gauge template sheet is shown in the figure.

Cut the static mixer at the position shown in the figure.

After taking out cartridge from packing box, check the followings;

  • No evidence of liquid leakage in the packing box.

  • No liquid leakage from bottom of cartridge .

CAUTION:

  • If leakage is found, gap filler is separated. Prepare a replacement [Battery Gap Filler Kit (Service Part: B9522 5MP0A)] without using it.

  • Check carefully for leakage because liquid is colorless.

Set static mixer to cartridge.

Set cartridge to the gap filler gun [SST: BP2000400Z (J-53350)].

Attach guideline label to cartridge as shown in the figure.

CAUTION:

Since guideline labels are depending on specification of battery and attached positions, select and attach specified one.

Guideline label : B-84 ml

Apply gap filler in accordance with lines written on the battery pack lower case.

CAUTION:

  • Apply one row using one scale on cartridge. (If there is surplus, add it to a place with less amount.)

  • If gap filler is applied thicker than the width of the lines, the amount will be short, so be careful.

  • When applying gap filler, if the coating bead contains colorless liquid , stop to use it because gap filler is separated and prepare a replacement [Battery Gap Filler Kit (service part:B9522 5MP0A)].

  • The process from the start of gap filler application to the completion of module installation (including tightening bolt ) must be within 1 hour.

NOTE:

One cartridge can be applied for just one module.

Install guide pin [SST: KV99119600 (J-53348)] to battery pack lower case.

Install module in the reverse order of removal.

NOTE:

When installing module mounting bolts, remove guide pin [SST: KV99119600 (J-53348)].
