Safety Interlocks
If the BMS detects a serious internal fault, it can take either or
both of two actions to prevent damage to the power pack:
• Throttle Disable. The BMS disables the throttle if the power
pack is empty, or if the BMS detects certain serious internal
problems. You cannot ride the motorcycle until the problem is
resolved.
• Charger Disable. The BMS prevents charging if it detects
certain serious internal problems - even if the power pack is
connected to a charger and plugged in to AC power. The
power pack cannot be charged until the problem is resolved.
Throttle Disable Interlock
The BMS communicates with the main motorcycle control
module. The BMS can send a signal to the main motorcycle
controller requesting that the throttle control on the motorcycle
be disabled. When the throttle control is disabled, the motor will
not deliver power to the rear wheel, and the motorcycle cannot
be ridden.
If the throttle is disabled while riding, the motorcycle will cease
to provide power, and the operator must pull over to a safe
location.
Charger-Disable Interlock
When the charger is attached and plugged in to AC power, the
BMS communicates with the charger. The BMS can send a
signal to the charger requesting that charging terminates
immediately. When the charger is disabled, the indicator lights
on the charger displays that charging has stopped.
There are two conditions that cause the BMS to disable
charging:
1. Too hot
The BMS detects an internal power pack temperature above
122°F (50°C).
2. Too cold
The BMS detects an internal power pack temperature below
32°F (0°C).
