LPI1010
The LPI1010 lets researchers and engineers perform EIS on large battery packs and fuel cell stacks.
- Three models - 10 V, 100 V, and 1000 V
- Galvanostatic or hybrid EIS up to 100 kHz — actual bandwidth depends on your electronic load or power supply
- 16-bit resolution
- Runs with an Interface 1010E alongside a bipolar power supply or electronic load
- Older Interface 1010Es need a factory upgrade before they can drive an LPI1010

High Voltage EIS Test System
for Batteries, Fuel Cells, and Electrolyzers
Vehicle electrification is requiring changes in how batteries and fuel cells are tested. Electrochemical impedance spectroscopy is a nearly universal technique for testing of batteries and fuel cells that helps understand device function. Until now, doing EIS on these large energy devices used in vehicles wasn't possible. Normal potentiostats don't have the voltage and current ranges necessary to test these devices. Gamry solves this issue with it's new High Voltage EIS Test System. The LPI1010 gives you the capability to perform EIS up to 1000V on these large systems.

System Information
A typical system consists of an Interface 1010E potentiostat and an LPI1010 working in conjunction with a Bipolar Power Supply or Electronic Load. A schematic of the system is shown below for impedance measurements on a battery. A similar arrangement can be used to measure a fuel cell.
The LPI1010 with a Power Supply measures the impedance of the Battery. The measurement of I and E at a given frequency allows the calculation of the impedance.
Older Interface 1010Es will require an upgrade at the factory before they can operate an LPI1010.
The Gamry LPI1010 is designed to accommodate the low impedance of batteries and fuel cells. It can measure complex impedance over a frequency range of 10 μHz to 100 kHz (the upper limit is determined by the electronic load or power supply).
Galvanostatic EIS on a 60.9V battery. 10kHz to 1 mHz. 0.5 A rms.
Key Features
The LPI1010 allows researchers and engineers to study large battery packs or fuel cell stacks where higher currents and higher voltages are necessary.
The LPI1010 when used in conjunction with an Interface 1010E modulates and external electronic load or power supply. This load or power supply is connected to the device under test (DUT).
The LPI1010 monitors the output current of the load or power supply, measures the voltage of the DUT at each applied frequency to compute an impedance.
