13. ELECTRONIC BATTERY CONTROL SYSTEMS (BMS) AND THEIR EFFECTS (CUT-OFF)
LI ION BATTERY PACK integrates the following electronic devices / systems with the function of managing the
safety of the cells that make up the BATTERY.
•
Emergency thermostat: intervenes during the charging phase in the event of a BATTERY charger failure which
could lead to battery overcharging. It prevents the BATTERY from overheating by cutting off the charging
current.
•
Cut - off: intervenes in case of attempt to overdischarge. It eliminates the electrical absorption by interrupting
the supply of current to the user device, it is restored by recharging the BATTERY.
•
Overcharge protection: during the charging phase it prevents the circumstance that the charger does not
automatically interrupt the charging period.
•
Short circuit protection: each cell inside the battery pack is individually protected electronically against
accidental short circuits, in any case DO NOT SHORT CIRCUIT THE BATTERY BECAUSE IT COULD
DAMAGE THIS SYSTEM IRREPARABLY and the BATTERY should be replaced.
•
Auto OFF system: the battery is equipped with a protection system against accidental discharges. It provides
for the interruption of the voltage in case the scooter is left on for more than 4 hours without using it. To restore
operation, simply turn off the scooter by turning the switch to the OFF position, wait at least 5 seconds before
turning on again.
Particular attention must be paid to the presence of the cut-off system as its intervention determines the supply of
energy to the Scooter and this occurs suddenly.
The non-operating condition imposed by the cut-off system is temporary and normal operation is restored after
having recharged the BATTERY using the special charger. The cut-of intervention is to be considered the
electronic BATTERY protection system against accidental total discharge, it is located inside the BATTERY and is
connected in series between the BATTERY and the Scooter motor.
The function is to prevent the excessive discharge of the cells with the possible danger of reversing the polarity of
one or more cells, with consequent possible destruction of the BATTERY pack with the potential to create even
very serious damage to things and / or people.
During the discharge of the batteries, the voltage drops until it reaches a limit value at which point the cut-off
prevents, by interrupting the power supply, the BATTERY can be discharged further.
When the cut-off intervenes, the battery no longer supplies voltage to the connector.
To restore the situation of use of the battery, it is necessary to recharge it only by means of the special battery
charger (see user manual of the battery charger) and restore the circuit.
The cut off intervention is to be considered exceptional and this event should not occur during normal use of the
battery, as the correct use of the vehicle does not require excessive discharge of the same.
13.1. IN THE EVENT OF CUT-OFF INTERVENTION
In case of intervention of the cut-off system, proceed as follows:
•
Follow the procedure for opening the scooter;
•
Disconnect the battery motor power connector;
•
Remove the battery from the Scooter;
•
Leave the battery to rest for at least 2 hours: this is the minimum time necessary, in this case, to allow the
battery to cool down and return to the waiting state for charging;
•
Connect the battery charging connector to the battery charger;
•
Proceed with charging, following the instructions in the battery charger user manual.
IMPORTANT NOTE!
Remember that when the cut off device intervenes, the Scooter inevitably stops
working.
This event must in no way be a source of danger for the diver, who will have
planned the diving activity taking into account that the use of the Scooter cannot
be considered as a system to safeguard one's life or to get out of situations. of
difficulty.
SUEX s.r.l. declines all responsibility following the intervention of the cut off system, in any situation, in
dangerous situations or in dives where the diver has (at his complete risk) entrusted his return to the
surface to the Suex Scooter.
IMPORTANT NOTE!
After using the Scooter, always cut off the power supply to the motor by using
the Scooter main switch: the electronic control of the Scooter motor board, even
with the engine not running, has a very low energy consumption which, in the
long term, can lead to complete discharge of the BATTERY, with possible
irreversible damage of the BATTERY PACK.
