NOTICE
Crossing PIN functions may cause system damage. Do not terminate unused wires
to ground, power, or other functions. Isolate unused PINs.
5.6 Lifting Points
The battery lifting points are
designed to be used with a
standard golf cart battery
lifting strap.
6. THEORY OF OPERATION
6.1 Ingress Protection IP67
Ingress protection rates the degree of protection provided by mechanical
casings and electrical enclosures against intrusion, dust, accidental contact,
and water under specified conditions. The IP67 rating includes testing that
indicates no ingress of dust particles and no ingress of a harmful quantity of
water when immersed for up to 30 minutes.
IP codes guide suitability for use under different environmental conditions.
IP ratings do not indicate fitness for purpose or confer a performance
guarantee.
6.2 Internal Heating
The battery is equipped with internal heating. When the battery’s internal
temperature is below 0°C (32°F), the charger’s current will be directed to the
heating element. When the battery's internal temperature has reached 2°C
(36°F), heating will stop, and the battery BMS will then direct the current to
charge the cells.
When internal heating is active, discharging the battery is not possible.
6.3 Battery Management System
6.3.1 Battery Management System Protections
The Battery Management System’s (BMS) primary function is to monitor
cell module voltage and temperature and battery current. The BMS uses this
information to maintain cell operation within specification. If a parameter
falls outside of operating specifications, the BMS will disconnect and
protect the battery from:
1. Overvoltage.
Protection occurs when charge voltages are too high.
2. Undervoltage.
Protection occurs during discharge when the voltage is
discharged too low.
3. Over-current.
Protection can occur during charge or discharge. This
may happen when powering up a load (high inrush current) or from a
Lifting strap.
