3.1 CONNECTIVITY
Your smartphone gets informaon from carBMS
through Bluetooth. Aer installing the app on your
smartphone, you have to connect your
smartphone to carBMS. When you run the carBMS
app for the rst me, the following screen will be
displayed.
Click on the CONNECT buon to pair the carBMS
device with your smartphone. The app will list all
devices available for connecvity including car-
BMS. The carBMS device can be easily idened as
it will be displayed as ‘CBMSXX’ where ‘XX’ is a
serial number. In the example below, the carBMS
device is displayed as CBMS10.
Touch to select the device.
The carBMS smartphone app will now connect to the device. When the connecon
is established, you will see the following message.
The app will now start communicang with the carBMS device. The app will tell you
that it has started communicang with the device with the following message.

3.2 ENTERING YOUR CAR DETAILS
The rst thing we need to do is to link the smartphone app with the carBMS device
on your car through an unique idencaon. The idencaon is your car registra-
on number. Please make sure you enter the car registraon number details in full.
If your car registraon number is UAE HJ 55678, enter it in full and not just 55678.
This is important as we need to link the data coming from your car to your car only.
If you try to proceed without entering your car number, you will be prompted to
enter the car number with a pop up message as shown.
3.3. ALERTS
An alert condion happens when certain parameters cross the thresholds specied
for them. For example, if you say the temperature should not be more than 70 de-
grees, that is considered an upper threshold limit. Similarly, if you specify that the
Voltage should not be less than 10V, that is considered as the lower threshold limit.
Whenever we sense the temperature to be more than 70 degrees, we consider that
to be an alert condion. When this happens, the app creates an alert and sends the
alerts to you through mulple channels.
3.4. ALERT FREQUENCY
You have to remember two important things here.
1. The alerts
2. The frequency of the alerts
When you specify an alert condion, we will send you an alert when the condion
is met. When you specify a frequency, it tells carBMS how oen to send you an
alert ll you act on the alert. If you specify 5 minutes as the frequency, carBMS will
keep sending you an alert once every 5 minutes as long as the alert condion is
met. In other words, if the situaon stabilizes, the alert will not be sent.

3.4.1.MULTIPLE ALERTS
The carBMS sends alerts to mulple devices. An immediate audio and visual alert is
sent to your smartphone on which the app is installed. In addion, alerts in the
form of SMS and missed calls are sent to two other phones. Over that, two emails
are also sent to two email addresses. In the following pages, we will show you how
to specify the phone numbers and email addresses to which the alerts will be sent.
Remember, these values can be changed anyme.
3.5. SETTING ALERT PARAMETERS
The alert parameters tell us when to send you
an alert or warn you of a potenal dangerous
situaon. Each alert will have two status
thresholds – minimum, and/or maximum. If
the status of the baery falls below the mini-
mum value, we will give you an alert. Similarly,
if the baery status moves above the maxi-
mum value, we will give you an alert.

User Manual

3.5.1. VOLTAGE
Set the minimum and maximum voltage.
As per the sengs shown above, the baery voltage should not exceed 14.75 volts
or fall below 10.5 volts for an extended period of me. Should the Voltage drop
below or exceed these limits, an alert will be sent to your smartphone.
Usually, the user manual that came with the baery will have the default values.
Use these to set the limits. If you are unsure about what to specify, leave the de-
fault values as such.
If you try to proceed leaving these elds blank, you will be prompted to enter the
minimum and maximum voltage values.

User Manual

3.5.2. TEMPERATURE
Enter the absolute maximum temperature the baery can endure inside the car
bonnet. Though most of us do not bother about this, very high temperatures can
aect the performance of the baery and aect its life.
The next queson is, what to do if you get an alert for high temperature. We would
advise you to stop the vehicle, and inspect the engine area. If you see smoke or get
a burnt smell, you have to take acon. If you don’t see anything amiss, there may
not be something to worry about immediately.
In any case, menon this to the service team when you take the car for servicing
next.
The opmum temperature of the baery usually varies between 40°C to 50°C. Dur-
ing peak summer, it could go upto 80°C or more. Maximum limit is 200°C aer
which the baery could possibly explode.
When the temperature exceeds the limit that is set, an alert will be sent to your
mobile device and you should immediately stop the vehicle and check. If you are
unsure about the maximum temperature, please leave the default values as such.
3.5.3. CURRENT
Current is the amount of energy that is drawn from your baery by the car. In gen-
eral, when the engine is running during dayme, the current drawn will be between
0-40 amps. When you start the engine, the starter motor will draw close to 80
amps, but this is for a few seconds. At night me, when you have the headlights on,
the current drawn could hover around 0-10 amps. We consider current of up to 100
amps as normal. Anything over that one a connuous basis means something is not
working properly in your car.
Enter the maximum current (Amps). Should the current exceed this limit, an alert
will be sent to your smartphone. If you are unsure about the maximum current,
please leave the default values as such.

3.5.4. MOBILE NUMBER
As we menoned before, in addion to giving immediate alerts to you, carBMS can
also send alerts to two other phone numbers you specify. The alerts are sent in two
ways
a. Giving a missed call. carBMS will dial the number you specify and disconnect
aer two rings. You will only see a missed call alert from the number you speci-
ed. Please do remember to tell the person whose number you specify, the
reason for the missed call.
b. Sending an SMS. carBMS will send an SMS message in the following format to
the number you specify alerng the person to an abnormal situaon in your
car’s baery
The number of mes these alerts are sent are based on the alert frequency you
specify.
It is mandatory that you enter at least one
phone number, Aer entering at least one
phone number, check the boxes under
Dial or SMS or both to specify how you
want the alerts to be sent.
Enter your primary mobile number in
the Mobile No.1 text box. This is man-
datory.
Enter your secondary mobile number in the Mobile No. 2 text box. This is opon-
al.
Check Dial to make a missed call.
Check SMS to send an SMS message.
Check both Dial and SMS to make as call and send an SMS.
Uncheck both Dial and SMS or leave the oponal mobile number text box empty
if you want to receive no alerts. Even if you enter a number, but leave the check
boxes empty, no acon will be taken for that number.

3.5.5. ALARM
Check the Alarm check box to enable push nocaons when there is an alert. It is
enabled by default. Should you choose not to receive nocaons, uncheck the
check box.
Enabling Alarm will send you a nocaon every me an alert is sent via an SMS or
a phone call. This is to let you know why the alert was triggered.
3.5.6. EMAIL
In addion to sending alerts to one or two other phone numbers, the carBMS can
also send email alerts to email addresses that you specify. Again, like phone num-
bers, one email address is mandatory.
 Enter your email address in Email 1 text box. This is mandatory.
 Enter your secondary email address in Email 2 text box. This is oponal.

3.5.7. REPEAT FREQUENCY
It is important to understand this clearly. Re-
peat frequency is the number of mes the
alerts will be sent to the phone numbers and
the email addresses you specify. The repeat
frequency works as described below:
a. When a parameter crosses the thresholds
you have specied, the alert mechanism
will be triggered. If you specify the alert
frequency as 5 mins, an alert will be sent
to you for every ve minutes.
b. If all the parameters become normal, all
alerts will stop, irrespecve of the repeat
frequency you specify.
Choose your repeat frequency carefully. If
you give a large gap, you may miss a poten-
ally hazardous situaon. If you specic a
very small gap, you will receive alerts very
oen and that may be annoying. Understand
the condion of the baery, and set the alerts
frequency to a number that enables you to
take correcve acon.
A Note On The Default Value Of 30 Minutes
We have set the default value to 30 minutes with the assumpon that your baery
is in good condion and behaving normally. When you set the alert parameters and
anyone of the parameter is crossed, carBMS will immediately trigger an alert. With
the default value set at 30 minutes, the next alert will be sent in 30 minutes IF the
alert condion connues. Thus if you have a good condion baery, and you keep
geng the same alert every 30 minutes, there is something amiss and you need to
check your baery.
If your baery is old, we would advise you to set the repeat frequency at 15
minutes or less.
Enter the repeat frequency of alerts (in minutes) in the Repeat Frequency text box

3.6 GRAPH INTERVAL
carBMS generates graphs that show you the status of each baery parameter. If
the graph is a straight line with small variaons, that means that parameters are
stable. If the graph uctuates dramacally, that is a cause for worry.
The graph is drawn based on the me frequency you specify. carBMS reads baery
data literally every second. That will be too small a me frequency to set for graph
purposes. In general, looking at a graph with a me frequency between 5-10
minutes would make sense. You can choose from three values. (1) 5 minutes (2) 10
minutes, and (3) Minmax.
Minmax enables you to view the whole day’s data.
Combining the graph me interval intelligently with the alert frequency will give
you the power to manage your baery perfectly.
Set the graph interval by selecng one of three values from the drop down list.
3.7 GRAPH DATA
The six baery parameters are based on the me interval you specify. Examples of
the graphs are shown below.
