AH54.10-P-0006-01A Note On The High-voltage Battery

General information on the high-voltage battery
^ When properly used the high-voltage battery will not present any hazard.
^ Avoid inhaling any dust, vapors or mist.

Additional information on handling and safety requirements is available in the High-voltage battery safety data sheet in the Daimler Hazardous Materials Management System
http://gms.aftersales.daimler.com.

Note on safe handling
^ There is a risk of explosion if mechanical forces or heat act on the high-voltage battery.
^ Do not subject high-voltage batteries to direct heat, welding and do not throw them into the fire.
^ Do not exert any pressure on high-voltage batteries and do not deform them.
^ Improper use can result in leakage, evaporating electrolyte flue gas, and - where ignition sources are present - fire and explosions.
^ Ensure that there is always sufficient air exchange and/or evacuation in the working premises.
^ Wear personal protective equipment (for high-voltage batteries that are not transport protected):
- Safety glasses
- Electrical protective gloves

Storeroom and container requirements
^ Because short circuits can result in burns, leakages and risk of explosion, the batteries must never be stored in bulk containers.
^ Keep in a cool and well-ventilated location.
^ Protect against humidity.
^ Avoid any ingress of the product into the sewage system, water drains or the ground.

General information on transport
The high-voltage battery presents hazardous material and is classified in line with the international dangerous goods regulations as:
UN 3480 lithium-ion battery, Class 9, Packaging group III. High-voltage batteries may only be transported in compliance with the applicable international and national dangerous goods regulations for each particular mode of transport.
Each high-voltage battery is to be checked with regard to suitability for transportation before any renewed transport. High-voltage batteries that have been damaged, are to be classified as NOT safe for transport, where in conjunction with the transport:
^ A hazardous increase in heat may exist.
^ High-voltage battery fires or short circuits may be caused.
^ In any other manner a hazard may be created, e.g. through release of liquid electrolyte or combustible, etching or toxic vapors.

A shipment must be conducted or authorized by a qualified logistics staff member.

High-voltage batteries safe for transport
High-voltage batteries safe for transport may only be shipped in the original packaging, insofar as the high-voltage battery was packed in accordance with the as-delivered condition. The following requirements must at least be observed:
^ The high-voltage battery is to be safeguarded against external short circuits, e.g. by using a terminal cap.
^ All openings on the high-voltage battery, in particular, the coolant connections, must also be sealed.
^ The high-voltage battery is to be free of any hazardous contamination on the outside.
All requirements with regard to flawless condition of the packaging, the sealing of the packaging using adhesive tape and dual strapping, the identification of the packaging as per the relevant dangerous goods regulations, as well as additional requirements with regard to transport must be observed

High-voltage batteries not safe to transport
A high-voltage battery is deemed to be UNSAFE for transport according to the following criteria:

Test with STAR DIAGNOSIS
^ High-voltage battery without diagnosis capability.
^ Insulation fault (clear assignment of high-voltage battery, fault code stored).
^ Contactor closed status (after circuit 15 OFF, fault code stored).

Current notes are available in Star Diagnosis.

Visual inspection
^ Crack in housing
^ Housing deformed
^ Housing tarnished.
^ Electrolyte leakage
^ High-voltage connection damaged.

High-voltage batteries that are not safe for transport may only be transported in road traffic or maritime traffic with exemptions issued by the responsible national authorities and in keeping with the systematic application of the exemption's specified conditions. High-voltage batteries that are not safe for air traffic transport must never be transported by air.
