Battery BMS parameters
3.6.1. Protection circuitry for Li-Ion will support currents up to
100A continues with:
3.6.1.1. Over current protection. (OCP)
3.6.1.2. Short circuit protection. (SCP)
3.6.1.3. Over voltage protection. (OVP)
3.6.1.4. Under voltage protection. (UVP)
3.6.1.5. Over temperature protection. (OTP)
3.6.1.6. Cells active balancing, With fault limitation.
3.6.2. BMS will support RS-485 & SMBUS communication, to
enable monitoring of battery status:
3.6.2.1. Pack Voltage and Current (including current direction)
3.6.2.2. Pack actual capacity / fuel gauge (SOC%)
3.6.2.3. Pack health – related to max capacity of the pack when
new (SOH%)
3.6.2.4. Pack Error Status, for all protection parameters;
balancing status, OCP, SCP, OVP, OTP, UVP
Major advantages of Lithium Iron Phosphate:
Very safe and secure technology (No Thermal Runaway)
Very low toxicity for environment (use of iron, graphite and phosphate)
Calendar life > 10 ans
Cycle life : from 2000 to several thousand (see chart below)
Operational temperature range :up to 70°C
Very low internal resistance. Stability or even decline over the cycles.
Constant power throughout the discharge range
Ease of recycling
Life-cycle ofLithium Iron Phosphate technology (LiFePO4)
Longer battery life, the life expectancy is two times that of lead-acid batteries.
Rechargeable and no memory effect.
The weight is more lighter.
Smaller dimensions and can be customized.
Safer and more environmentally friendly, No heavy metals and hazardous substances.
BMS built-in IC chip will prevent battery pack over charge, over discharge, over-current,
over-heat, short circuit .
