ECU CONTROL UNIT - INSIDE LOOK
The ECU is the “brain” of bSeen’s system. Inside the ECU there’s a 12V
Samsung battery pack with three 18650 batteries in series, with a total
current output of 3000mAh (3A). To manage the charge and the discharge
cycles, the battery pack is monitored by an electronic balance
management circuit, which guarantees the batteries’ performance. The
balancing management circuit is rated to 20A, with enough margin to
manage the 3A output current from the battery pack.
bSeen’s electronic circuit has protections against short circuits. Three layers
of protection were developed to ensure the batteries stay safe from any
problem that can arise from a short circuit. There’s are also internal quick
blow fuses for LED units and charger port, in case that any overload occurs.
To control the functions provided by the handlebar switch unit, inside
bSeen there’s a pre-programmed micro-controller.
To provide power to the LED units, each LED unit’s output from the ECU is
driven by a transistor, ensuring each LED’s high brightness at all times.
WARNING
The ECU contains micro electronics and it’s powered by a 12V li-ion
battery pack. Li-ion batteries are extremely dangerous if not handled
with care.
The li-ion battery pack inside bSeen’s ECU takes about 80% of the
internal ECU’s room, so please keep in mind:
• DO NOT open the ECU
• DO NOT drill the ECU
• DO NOT put the ECU under any sort of pressure
• DO NOT expose the ECU to direct sunlight during long periods of
time.
• DO NOT expose the ECU to extreme heat
