General description and features

The EFL700A39 EnFilm

•

Low thickness

•

Low self-discharge

•

Extremely long calendar and cycle life time

•

High safety with no risk of burning or explosion

EFL700PMB and EFL700EVALKIT kits were developed to help designers to evaluate the

charges and discharge performances of the EFL700A39 with a proper setup of power

management.

The EFL700PMB includes one PCB: The power management board (PMB), same size as

the EFL700A39 battery mounted on the bottom side.

The EFL700EVALKIT includes two PCB: The power management board (PMB) and the

additional load board (LB).

The power management board (PMB):

•

Manages the charge and the voltage regulation of the EFL700A39

•

Protects battery against deep discharge

•

Supports the recharge through an external energy harvesting

•

Includes a CELLERGY super cap to sustain high pulsed discharge current. The super

capacitor can be disconnected with the switch SW1

The PMB can be used in association with USB port, photovoltaic panel or any kind of

harvester with its own power management. The PMB can be connected to any kind of load

with its own power management circuit.

Whatever the harvester and load system are, the PMB allows a safe and efficient use of the

EFL700A39 micro-battery.

The load board (LB):

•

Includes an analog ammeter and a digital voltmeter allowing the user to monitor:

–

The current delivered by the source by pressing PB1.

–

The current going through the EFL700A39 battery by pressing PB2.

–

The battery voltage

•

Includes a pulsed load emulator with the possibility to adjust the pulsed load cyclic

ratio. Its features are:

–

Enable / disable function by toggling the switch SW3.

–

Default pulsed load current set to 5 mA during a pulse time of 100 ms every 10 s.

–

Tunable pulse duration from 1 ms up to 130 ms through RA1 rheostat.

–

Tunable pulse repetition time from 2 s up to 14 s through RA2 rheostat.

The LB can be powered via 2 mm banana connectors or a micro-USB plug.
