ELPROG Pulsar-EQUAL Instructions Manual

PULSAR-EQUAL v 1.10

Art.No.: 1126

10.12.2011

The Pulsar-EQUAL is a professionally designed and built, micro processor controlled balancer/equalizer and
tester. The Pulsar-EQUAL is able to equalize the voltage of single cells in an accupack in a very sh ort time. All
types of Lithium-Accus from 2 to 12 cells can be equalized. Because of the very high continuous performance
even high capacity cells can be handled in a minimum amount of time.

The development of the Pulsar-EQUAL concentrated on offering most complete and precise information of each
cell in an accupack. The display informs in detail about all operations in real-time and the voltage of all cells is
visible at all times. The entire processing can be captured by a PC and allows interpretation and comparison at a
later point in time.

In order to keep the charging time to the minimum, the Pulsar-EQUAL offers a very high equalizing
performance of 45 W with a maximum equalizing current of 4 A, limited to 0.75 A per single cell. The Pulsar-
EQUAL controls all charging parameters of the cells and is able to communicate with chargers like the Pulsar 2
or Akkumatik to reduce the charge or discharge current, if required. The Pulsar-EQUAL will even initiate an
emergency shut down of the charging process, if the positive charging leads are connected to it.

During the equalizing process, the cells with the highest voltage in the accupack deliver the energy for the cells
with the lowest voltage. This principle increases the overall efficiency and reduces the load on the power supply,
e.g. a starter battery.

Introduction

Lithium-Accus are to be charged with the CC/CV (Constant Current/Constant Voltage) process. A specific
charge cut off voltage per cell should not be exceeded. For lithium-polymere cells this charge cut off voltage is

4.2 V. Charging above this voltage will damage the cell and may result in total de struction with the danger of
fire or even explosion.

When using li-po-accupacks, the voltage of the cells in an accupack tend to drift. This can lead to dangerous
voltage differences between the cells in an accupack.

Example: If you want to charge a 5S-Li-Po-Accupack, the charger will charg e the pack to the charge cut-off
voltage of 21V. (5 x 4.2 V). Assume 4 of the cells have a voltage of 4,1 V then the charger would end the
charging process when the fifth cell has a voltage of 4.6 V. Overcharging th is cell is dang erous and may cau se a
fire. A balancer will avoid this and protect your accupack.

Balancer and Equalizer differ in the way they operate. A balancer can only equalize the cells during charging.
Once a cell reaches the charge cut-off voltage, charging of this cells is terminated by diverting the charge current
into resistors, converting the energy into heat.(like a Voltage Limiter) An equalizer is able to equalize the voltage
of cells in an accupack without the charging process. Up to date equalizers transfer the energy of the cells with
the highest voltage to the cells with the lowest voltage in the accupack. This principle is adopted by the Pulsar-
EQUAL. Balancing/Equalizing only makes sense at a certain voltage level. The Pulsar-EQUAL will start
equalizing at a voltage of 3.8 V per cell and will apply its full perfo rmance once the cell h as reached a voltag e of

4.0 V.

It should be mentioned, that equalizing of the cells in an accupack is not required at each charge. You will learn
from experience, how your accupacks perform regarding voltage drifting of the cells and you will know, when to
equalize the accupack.

However, we suggest to use the Pulsar-EQUAL at all times, to play it safe and always have full control over
your expensive lithium accupacks.

Device Connection

Accupack

Connect your accupack (2 to 12 cells) with the Pulsar-EQUAL via the 15 pole plug. Please mind the polarity
and pin connections. False connections may result in damaging the Pulsar-EQUAL or your accupack. The
proper connection of pins and cells in an accupack is shown below (refer to left drawing).

Connector

on Equal

We recommend to use our accu interface, providing a communication cable to the Pulsar 2 charger and a
connection socket for the temperature sensor. The accu interface also allows to install the most popular balancer
plugs in use today (for details, refer to the drawing at top right). If you are planning on your own balancer
system, keep in mind, that pins 8 and 15 can be used to establish a connection to the Pulsar 2 via the temperature
sensor socket. In mounting a parallel temp socket to these pins, the temperature sensor will stay operational.
Required plugs, sockets and cable are available from your local electronic parts shop.

Charger

As usual, you select the desired charge
parameters at the charger. Next, you connect
the positive charge lead of the charger to one
of the red connection sockets of the Pulsar-
EQUAL. At the other red socket you connect
another charging lead to connect the
accupack. Now you connect the
communication cable to the temp sensor
socket of the Pulsar 2. Following you connect the n egative charging lead to the charger and the accupack.. After
this, you connect the balancer cable to the Pulsar-EQUAL. You are now ready to select the Pulsar-EQUAL
parameters and to start the process. Attention – the disconnection of the plus wire will be active until the
Pulsar-EQUAL is started. Before starting the Pulsar-EQUAL, the charger will not detect any accumulator. The
loop in of plus wire is not necessary if the charger can communicate with the Pulsar-EQUAL via data cable.
