Advantages
Ability to opportunity charge quickly without detriment to life can allow multi shift
- peration 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 2017 WHERE 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 Freestanding batteries installed by suppliers and dealers being superseded by OEM installed ‘integrated’ battery from the factory to gain: Battery charge level gauge and ‘lift lock out’ functionality Controlled depower of machine in event of battery shut down Diagnostics and certification 3
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.

ADVANTAGES OF LI ION AT THIS SIZE ADVANTAGES OF LI ION AT THIS SIZE
Lead Acid Battery becomes less efficient as it heats up Lower efficiency Causes 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 law Impacts lead acid battery efficiency in intensive applications 13
