6 FAQs about [Battery pack power measurement method diagram]

How do you measure a battery pack voltage?

Battery pack voltage, using a high-voltage resistor divider. Shunt temperature, using a thermistor. Auxiliary measurements, such as the supply voltage, for diagnostic purposes. As demand for batteries to store energy continues to increase, the need for accurate battery pack current, voltage, and temperature measurements becomes even more important.

What is a battery pack design?

This design focuses on e-bike or e-scooter battery pack applications and is also suitable for other high-cell applications, such as a mowing robot battery pack, 48-V family energy storage system battery packs, and so forth. It contains both primary and secondary protections to ensure safe use of the battery pack.

How does a BMS measure a battery pack?

Generally, a BMS measures bidirectional battery pack current both in charging mode and discharging mode. A method called Coulomb counting uses these measured currents to calculate the SoC and SoH of the battery pack. The magnitude of currents during charging and discharging modes could be drastically different by one or two orders of magnitude.

How does a BMS measure bidirectional battery pack current?

Therefore, in discharging mode, current flows in the opposite direction from charging mode, out of the HV+ terminal. Generally, a BMS measures bidirectional battery pack current both in charging mode and discharging mode. A method called Coulomb counting uses these measured currents to calculate the SoC and SoH of the battery pack.

How do you design a battery pack?

When designing a battery pack, it is important to weigh different parameters against each other to acheive a suitable design. It is therefore significant for these tradeoffs to have a valid foundation to stand on. One tradeoff that needs to be accounted for is comparing safety of the battery against its weight.
