BMZ is based in Germany.
Service of the BMZ battery is supplied by HYG. HYG Service organization is ready to support.
A BMZ battery is warranted for 5 years/10,000 hours, recovery of the warranty and part replacement will be through the HYG warranty system.
It depends on the issue. Basic diagnosis and connection repairs can be done. There is no expectation that dealers will fix major problems, which require opening the battery.
A replacement battery will be available directly from HYG stock, held for us at BMZ in Germany. HYG Aftermarket is setting up that supply arrangement.
Yes, we are now able to quote via SPED a double pack version of this battery with 112Ah capacity.
Currently, only a 20A high frequency on-board charger is available.
At present, only the supplied on board charger is equipped with the correct charging profile for this battery. When an external charger is available, it will be different from a charger used for a lead-acid battery.
Current on-board charger takes 2-3 hours
Not with current on board charger.
The bulk charging rate, using the onboard charger, is 20A per hour. So a 56Ahr battery taken to 90% depth of discharge (50.4Ahr discharged) requires approximately 2.5hrs (50.4Ahr/20A) to return the full discharge. The recharge will be approximately linear. Note that onboard charger output performance, like wall chargers can be hampered by low efficiency grids. We have encountered scenarios with longer than expected times. The root cause was low power factor conversion from the grid which proportionally extends recharge time. Power factor management is part of standard operating practices in factories, and these losses occur on all trucks in a facility that is unable to achieve a good power factor.
The number of cycles with Li-ion is expected to be 4000, compared to 1200-1500 for lead-acid batteries. A particular and useful difference with Li-ion is that opportunity charging (partial charge added to a battery in a lunch break for example) does not diminish the life of a Li-ion battery as it does a lead-acid battery.
There is the Lithium-ion Application Tool for the Pedestrian Pallet Truck, which checks the suitability of the BMZ Li-ion battery in a typical application, i.e. unloading lorries. Calculations are based on a number of actual tests. The Lithium-ion Battery Calculator Tool can also be used for this truck and provides an estimation of the costs and Return on Investment (ROI) in years. Both the tools are available from Q4 2017.
