ZHCSD95D January 2015 – April 2021 BQ34Z100-G1
PRODUCTION DATA
The default setup of the BQ34Z100-G1 is for Li-ion chemistries.
The charge-termination specific configurations include:
Class Name | Subclass Name | Parameter Name | Default Value | Units |
---|---|---|---|---|
Configuration | Charge Termination | Taper Current | 100 | mA |
Configuration | Charge Termination | Min Taper Capacity | 25 | mAh |
Configuration | Charge Termination | Cell Taper Voltage | 100 | mV |
Configuration | Charge Termination | Current Taper Window | 40 | s |
When changing to Lead Acid chemistry there are further configuration options.
Class Name | Subclass Name | Parameter Name | Default Value | Units |
---|---|---|---|---|
Configuration | Charge | Pb Temp Comp | 25% | |
Configuration | Charge | Pb Reduction Rate | 10% |
When using Nickel Metal Hydride (NiMH) or Nickel Cadmium (NiCd) batteries, the charge termination criteria change significantly.
Class Name | Subclass Name | Parameter Name | Default Value | Units |
---|---|---|---|---|
Configuration | Charge Termination | NiMH Delta Temp | 3 | 0.1°C |
Configuration | Charge Termination | NiMH Delta Temp Time | 180 | s |
Configuration | Charge Termination | NiMH Hold Off Time | 100 | s |
Configuration | Charge Termination | NiMH Hold Off Current | 240 | mA |
Configuration | Charge Termination | NiMH Hold Off Temp | 25 | 0.1°C |
Configuration | Charge Termination | NiMH Cell Negative Delta Volt | 17 | mV |
Configuration | Charge Termination | NiMH Cell Negative Delta Time | 16 | s |
Configuration | Charge Termination | NiMH Cell Neg Delta Qual Volt | 4200 | mV |
To switch the charge termination criteria suitable for NiMH/NiCd, set the [NiDT] and/or [NiDV] bits. See Section 7.3.11 for further details.
Where:
NiDT: Performs primary charge termination using the ΔT/Δt algorithm.
NiDV: Performs primary charge termination using the –ΔV algorithm.
When a Nickel-based chemistry Chem ID is used, then the Li-ion/PbA charge termination method is NOT used regardless of the configuration of the NiDV and NiDT bits.
