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).
