Where is BMZ based? 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 will be available from October 2017.

Midac is based in Soave Italy near Verona, 2 hours from our Masate Plant.

Service of the Midac battery is through the Midac Aftermarket system in Europe.

A Midac Battery is warranted for 5 years/10,000 hours, recovery of the warranty and part replacement will be through Midac.

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. Midac will support in this case.

Battery support will be available directly from Midac.

Yes, competitive sizes are available.

External chargers are available, with low, standard and fast charging rates, matched to the battery. On-board chargers are not available at this point: the higher current draw of the chargers makes rapid connection to the mains supply less practical.

A Li-ion battery requires a carefully designed charging current profile and for this reason we offer matched chargers and warrant the battery for 5 years only when used with the matched charger. The battery is designed to only accept charge from a suitable charger, and will self-protect when unsuitable chargers are connected. Approval of existing chargers when adapted for Li-ion use may be possible.

With rapid chargers this may sometimes be necessary. The power requirements will be quoted in our materials for each charger. Overall power requirements do require some planning when larger fleets of rapid charged trucks are being considered.

The recharge will be approximately linear. It will take on energy at approximately the same rate.

The Midac battery has life expectation of 3750+ cycles at 80% DOD, lead-acid is often quoted at 1200-1500 cycles.

The Lithium-ion Battery Calculator tool is suitable for each truck equipped with Li-ion battery. The tool checks the suitability of the Li-ion battery and charger in the application and provides an estimation of the costs and Return on Investment (ROI) in years. The tool will be available from October 2017.
