CONSUMER INFORMATION BATTERY MANAGEMENT SYSTEM
Every Z-Force power-pack contains a Battery Management System (BMS) which monitors the condition of the
cells and optimizes the charging process to provide the highest-performance, longest-range, and longest-life for
the pack.
The BMS is sealed inside the Z-Force power pack. As a rider, you don’t need to think much about the BMS — it
just silently does its job as you charge, ride, and store your bike. There are only two things you might need to
know about your Z-Force BMS:
BEEP-SIGNALS
The BMS will emit an “OK” beep-tone every time you turn-on your bike. The BMS might also respond to other
internal conditions and errors with different kinds of beeps. This section explains the different beep-patterns and
their meanings.
SAFETY INTERLOCKS
The BMS can disable the bike’s throttle-control if the pack is fully discharged, or in case of other errors. The BMS
can also disable charging under certain circumstances. This document explains the different conditions which
can cause the BMS to disable the throttle-control or the battery-charger.
BEEPS
Where is the Beeper?
The BMS includes a piezoelectric beeper, sealed inside the Z-Force pack.
When Does the BMS Beep?
The BMS will beep under only two circumstances:
1. When the bike key-switch is turned from “Off” to “On.”
When the bike is turned-on, the BMS will perform a self-test. It will always sound a beep-signal
when the test finishes. The beep-pattern reports the self-test result.
2. Whenever the key-switch is “On,” and the power-pack is nearly empty.
The BMS will continuously sound a warning when the battery is low. The warning will stop when
the bike is turned-off, or when the pack is fully-drained.
