NiMH and Li ion Hybrid batteries recovery procedures and documents
Introduction
Toyota Motor Europe, as part of our on-going commitment to environmental projects, has established a recovery procedure for the sustainable recycling of industrial batteries from Toyota and Lexus full hybrid and electric vehicles in Europe.
Schematic flow for Toyota/Lexus Authorised Repairers
Schematic flow of HV batteries recovery for independent repairers, insurance companies and authorized end-of-life vehicle treatment facilities
According to the UN regulations for the transport of dangerous goods, Li-Ion batteries can’t be shipped to authorized repairers without a safety diagnosis.
Please refer to HV Battery Recovery inspection in TechDoc, or the one published in the International Dismantling Information System (IDIS – www.idis2.com).
1) Definition of defective / damaged and non-damaged batteries
1.1) NiMH batteries
A damaged NiMH battery is a battery showing external damages: electrolyte leakage, deformation, discolouration
In all other cases, batteries are not considered as damaged, and must be returned to TPCE from an Authorised Repairer.
1.2) Li ion batteries
A defective Li ion battery is battery showing certain DTC after initial diagnostic procedure.
Please refer to Repair Manual for complete DTC list that require Battery discharge.
In case of DTC the battery must be discharged using a specific discharge tool.
(see point 2.2 for more details)
A damaged Li ion battery is a battery showing external damages: electrolyte leakage, deformation, discolouration.
This battery must be discharged, using a specific discharge tool.
(see point 2.2 for more details)
Remark:
The repair manual indicates that damaged batteries must be discharged using the salt water method. This method is not authorised in Europe.
If the damaged battery does not permit the use of the discharge tool due to damaged connection poles or any other safety hazard, please store the battery in its current state at a secure location.
In case of any question, please contact TME MSSD.
In all other cases, batteries are not considered as damaged, and must be returned to TPCE from an Authorised Repairer.
2) Battery recovery procedure for Authorised Repairers
2.1) NiMH batteries
Non damaged batteries
Batteries will be returned to TPCE (from an Authorised Repairer), using the same principle as any other component Exchange system (order new part/return core unit).
Please note that Authorised Repairers have 20 days to submit their claims, and 20 days to return Core Units to TPCE.
For PL21 countries, please refer to following SOP’s:
(HVB PACKAGING INFO & SOP.xls)
(SOP for Hazmat documents for HVB.xls)
For non PL21 countries, Authorised Repairers must liaise with their usual Parts Logistics contact persons at NMSC’s.

2.2) Li ion Batteries
Non damaged batteries
Batteries will be returned to TPCE from an Authorised Repairer, using same principle as Component Exchange system (order new part/return core unit).
Please note that Authorised Repairers have 20 days to submit their claims, and 20 days to return Core Units to TPCE.
For PL21 countries, please refer to following SOP’s:
(HVB PACKAGING INFO & SOP.xls)
(SOP for Hazmat documents for HVB.xls)
For non PL21 countries, Authorised Repairers must liaise with their usual Parts Logistics contact persons at NMSC’s.
Defective Batteries showing particular DTC’s (do not consider as damaged!)
Please refer to Repair Manual for complete DTC list that require Battery discharge.
In case of discharge, a Li ion Battery Discharge Tool is needed. As usage will be very low at Authorised Repairer/NMSC side, TME decided to make it available on loan basis.
AR has to inform NMSC about Discharge Tool need, then NMSC informs TME Customer Service Support Div by e-mail or phone. (kevin.schauvaerts@toyota.europe.com) +32 2 745 2711 or
(Frederic.lebrun@toyota-europe.com) +32 2 745 27 42.
TME will send the Discharge tool within 2 working days directly to Authorised Repairer.
Once the operation is finished, Discharge tool will have to be sent back to TME within 2 working days.
The battery then needs to be sent back to TPCE using the reverse logistics procedure: SP188 & packaging instruction P903 (original OE packaging)
Damaged Batteries
As EU regulation on damaged Li ion battery transport will be finalised by 2015, it is currently not possible to transport them within EU. Authorised packaging is currently not available. Damaged batteries should be stocked at Local Authorised Toyota/Lexus Repairer until further notice.
3) Battery recovery procedure for Independent Repairers - Insurance Companies
