LITHIUM ION IN MATERIALS HANDLING LITHIUM ION IN MATERIALS HANDLING

Matthew Allen – Solutions Manager CB Products EMEA

LITHIUM ION IN WAREHOUSE MATERIALS HANDLING (NOT COUNTERBALANCE)LITHIUM ION IN WAREHOUSE MATERIALS HANDLING (NOT COUNTERBALANCE)

Advantages

Ability to opportunity charge quickly without detriment to life can allow multi shift operation without battery exchange

Cleanliness - Solid state and gas free when charging. Maintenance free.

More compact and lighter – beneficial in some cases (not Counterbalance)

Disadvantages

Battery cost – reducing but 4-6 X Lead Acid battery cost

Infrastructure and charger cost - installation at the workstation or lunch room may not be possible and can be expensive

Special transport and storage and disposal requirements

WHERE IS LITHIUM ION 2017WHERE IS LITHIUM ION 2017

Much interest, spurred on by journals and shows - limited sales, (less than 1% take-up), but at least doubling annually

Growing particularly in ‘clean’ industries– food etc where current technologies have limited performance.

Most likely to be justifiable in intensive applications using multiple lead acid batteries or LPG forklifts, and ‘new builds’ where chargers can be incorporated and installed from the start, or where space in battery room is needed for other uses.

Freestanding batteries installed by suppliers and dealers being superseded by OEM installed ‘integrated’ battery from the factory to gain:

Battery charge level gauge and ‘lift lock out’ functionalityControlled depower of machine in event of battery shut downDiagnostics and certification

SPECIFYING LI ION EQUIPMENT TO SATISFY AN APPLICATION REQUIRES ANALYSIS AND MODELLING

SPECIFYING LI ION EQUIPMENT TO SATISFY AN APPLICATION REQUIRES ANALYSIS AND MODELLING

Inputs

Application data provided by the customer particularly energy used in the application, measured or estimated.

Suitability for Li Ion based on application severity and shift and break patterns

Allows optimal size of Li Ion Battery and Charger to be selected

Total cost of ownership and payback for Lithium Ion v Lead Acid batteries

Modelling capability – allows calculation of how much charging during the shift would allow an application to move to Li ion.

ELECTRIFICATION OF COUNTERBALANCE FORKLIFTS (WHAT IS SO GOOD ABOUT LPG?)ELECTRIFICATION OF COUNTERBALANCE FORKLIFTS (WHAT IS SO GOOD ABOUT LPG?)

THE GAS BOTTLE

Cheap and tough 10 year life with no loss of performanceClean – cannot spill. Can operate -20C to +40CNo weekly ‘equalisation charge’ No battery room, eyebath requiredExchanged or filled by operator in a few minutes without any equipment

As Electric Counterbalanced Lift Trucks Get Larger, they are less suited to intensiveuse , due to limitations of Energy Needed v Energy on Board.Currently available ER cannot match productivity of Large LPG/Diesel

ADVANTAGES OF LI ION AT THIS SIZEADVANTAGES OF LI ION AT THIS SIZE

Lead Acid Batterybecomes less efficient

as it heats up

Lower efficiencyCauses Lead Acid Battery to heat up

At higher power outputs lead acid batteries become less efficient

Charging also generates heat – lead acid batteries need to cool before reuse.

3X lead acid batteries may be needed and exchange of batteries this size (typically 2000kg+) is difficult and time consuming

Peukert’s lawImpacts lead acid battery efficiency inintensive applications
