PowerPump Technology Transfers Charge
Efficiently From Cell to Cell During All
Operating Conditions, Resulting in Longer
Run Time and Cell Life
– Includes User-Configurable PowerPump
Cell-Balancing Modes
High-Resolution 18-Bit Integrating Delta-Sigma
Coulomb Counter for Precise Charge-Flow
Measurements and Gas Gauging
Multiple Independent Δ - Σ ADCs: One-per-Cell
Voltage, Plus Separate Temperature, Current,
and Safety
Simultaneous, Synchronous Measurement of
safety solution designed for large series cell strings.
The bq78PL116 along with bq76PL102 PowerLAN ?
dual-cell monitors provide complete battery-system
control, communications, and safety functions for a
structure of three up to 16 series cells. This
PowerLAN system provides simultaneous,
synchronized voltage and current measurements
using one A/D per-cell technology. This eliminates
system-induced noise from measurements and allows
the precise, continuous, real-time calculation of cell
impedance under all operating conditions, even
during widely fluctuating load conditions.
PowerPump technology transfers charge between
cells to balance their voltage and capacity. Balancing
Pack Current and Individual Cell Voltages
is
possible
during
all
battery
modes:

Very Low Power Consumption
– < 400 μ A Active, < 185 μ A Standby, < 85 μ A

discharge, and rest. Highly efficient charge-transfer
circuitry nearly eliminates energy loss while providing
true real-time balance between cells, resulting in
longer run-time and improved cycle life.
