- Facilitate the safe charging and discharging of lithium ion batteries;
- Gather and analyse data to increase operational performance and cell longevity;
- Forecast throughput and capacity attenuation given variable battery conditions; and
- Provide better State of Health (SoH) metrics and maintenance information.
| Parameter | Use |
| Voltage | Under/Over Voltage for basic BMS Safety and State of Charge (SoC)dV/dt for charge / discharge magnitude and duration |
| Temperature | Under/Over Temperature for basic BMS SafetydT/dt for extrapolation of internal stress |
| Current | For Coulomb counting to substantiate SoCdI/dt for determination of internal resistance |
| Internal pressure | Monitor for charge retention attenuation and SoH indicatordP/dt for internal battery fault warning |
BMS - Lithium Ion Vs. Lead Acid
As compared to Lead Acid batteries, Lithium-ion batteries are being used to deliver higher-quality performance in a safer, longer-lasting package, as detailed below:| Feature/ Battery | Lithium Ion | Lead Acid |
| Weight | One-third | |
| Efficiency during charging and rapid discharging | 100% efficient | Drops |
| Can be discharged | 100% | 50% to 80% |
| Cycle Life – Rechargeable | 1500 to 2000 | 300 to 400 |
| Voltage during discharge cycle | Maintain constant voltage | Drops voltage consistently |
| Life Cycle/ Upfront cost | Low/ Higher | High/Lower |
| Environmental Impact | Cleaner technology, safer |
