Bidirectional Current Battery Emulator Simulator for Battery
Operated Product DesignN8352 Series High-accuracy Dual-channel
Programmable Battery SimulatorA battery emulator is an electronic
device that simulates many real battery electrical properties
and characteristics. These characteristics are power, current,
voltage, etc. It supplies the needed voltage, power, and current to
a handheld device similar to a real battery does. Generally an
emulator will replace the battery inside a portable device for
testing purpose. The emulator empowers test engineers to easily and
thoroughly test these portable systems. Product
IntroductionN8352 series is specially designed for the R&D and
test of portable battery-operated products, such as Bluetooth
headsets, mobiles, AR/VR smart terminals, electric tools, etc. The
current flows in both directions and can be used as either a power
supply or a load. N8352 is easy to use with touch screen and UI
design. The output features are comparable to actual
batteries, with fast dynamic response, no overshoot in voltage rise
and fall, and stable waveform.The resolution is up to μA level,
which can test the static power consumption. N8352 can be widely
used in consumer electronics testing.Application Fields1.R&D

FunctionsPower ModeAs a dual-channel power supply, users can set
output voltage and output current limit value on N8352. N8352
provides multiple current ranges which can improve the output and
measurement accuracy.Battery SimulationN8352 dual channels
provide independent setting of initial voltage, internal
resistance, battery capacity and other related parameters, and
readback in real time. It can be used to solve the difficulty
of parameter uncontrollability for real battery in test and to
improve test efficiency.Fault SimulationN8352 provides the
following fault states: positive & negative polarity open circuit,
reverse polarity connection and short circuit.Current flowing
in both directions to make N8352 both a power supply and a loadThe
current flows in both directions. N8352 can both suck and output
current. The output terminal has a switch module, which can
physically disconnect from the external circuit in the closed
state.Variable output impedance allowing battery internal
resistance simulationN8352 has the battery internal resistance
simulation function, and supports resistance value
programming. The programmable range is 0-1Ω, which can emulate
the variation graph consistent with the real battery internal
resistance characteristics.Ultra-fast transient response without
overshootN8352 series can ensure there is no overshoot in voltage
changes under no-load or loading condition, preventing
damage to the DUT due to voltage overcharge and over
discharge. It can avoid bad effect to product quality. This feature
can meet the demand for product test with strict power
requirements.Application--Mobile TestMost consumer electronics are
powered by Li-ion battery, especially smartphones. Battery life
issues become prominent. Battery test regulation are becoming
stricter. Compared with real battery, it has the following
advantages to apply battery simulator. It can emulate the
battery change graph and shorten the test cycle. The reliability of
test data can be improved by repeated test on a given
model.Both channels of N8352 can charge and discharge. Thus either
channel can be used as a power supply, connecting to mobile
power terminal. The other channel can be used as a battery,
connecting to mobile battery terminal. Both charging and
discharging performance can be tested without changing the cables.
A single N8352 can be used to test a charge & discharge
protection board without additional switches, which greatly reduces
the complexity of the test system and improves testing
stability and efficiency.Advantages of battery simulation VS real
batteriesSuitable for any battery modelStatic power consumption
