Application

Battery test for electro mobility

A typical application for the electronic loads from EA Elek-

tro-Automatik is the testing of the electrical characteristics

of a battery. The wide application spectrum covers cell, mo-

dule or pack tests, the determination of the SOH (State-of-

Health) for a second life classication as well as the End-of-

Line (EOL) test. These applications put many demands on

power electronics which are fullled by the ELR 10000 ran-

ge. The excellent features of this device range are: measure-

ment of voltage and current with the required accuracy and

dynamism, reproducibility and reliability of these data and

the economic and exible usage. Whether in an automated

test system or in an integrated battery test, all possibilities

are open to the user. Furthermore, the devices are clearly

economic with eciencies of 96% or more.

Fuel cell test

The devices in the ELR 10000 range may be used for tes-

ting the electrical features of fuel cells, fuel cell stacks and

fuel cell systems. Here they generate highly accurate and

reproducible results in all electrical modes. To test the re-

sistance, performance, and active life of a fuel cell quickly

and economically users can readily incorporate the devices

into an automatic test system. The feedback capability gua-

rantees high level of energy and cost eciency. If higher

currents are needed for testing a complete fuel cell system,

then multiple devices can be connected in parallel in a mas-

ter-slave system. Here high accuracy and dynamism are

maintained.

On-board charger test

In an on-board charger test (OBC) the electrical features

must be tested under various conditions. This requires a

exible test system which also provides test data. With the

sequencing and logging functions of the ELR 10000 devi-

ces test procedures allow data to be read out and saved. In

this way applications can promptly generate reproducible

test results based on dynamic and highly accurate set point

and measurement data. To avoid competition between two

separate control loops of the device under test (DUT) and

the test device, the control frequency of the electronic load

is adjustable. The modes Normal, Fast and Slow allow the

ELR 10000 devices to match the control characteristics of

the on board charger.

Battery recycling

The programmable electronic loads of the ELR 10000 range

enable retired batteries from electric vehicles to be consi-

dered for a possible further use. Assessment of the battery

pack starts with a State of Health (SOH) check to determine

if a second life is feasible. This standard integral function

can be initiated by press button. If this check shows too litt-

le rest capacity, then the battery must be fully discharged

before recycling. The autoranging of the devices guaran-

tees the maximum possible total discharge though the high

load current, even with voltages under 2 V. The mains feed-

back of the power grid consumed of 96% eciency makes

this process highly cost effective.
