1. Quick Start guide

a) Connect DC cables to the charger and then the battery or batteries; ensure that there is a

good electrical connection and keep the terminals away from any surrounding objects that

could cause a short circuit.

b) Connect the AC power cable to a mains power outlet; the TEST LED will be illuminated or blink

when the Blue Smart Charger is powered up.

The TEST LED will continue to blink until a charge pulse is able to increase the battery voltage

above 12.5V (25.0V for 24V chargers) or 2 minutes have elapsed.

If a fault is detected during the test phase (such as a short circuit, reverse polarity or incorrect

charger voltage) all charge status LEDs will blink; in this case the charger should be immediately

disconnected.

c) Select the charge mode appropriate for the battery type; briefly press the MODE button to cycle

through the available options, the LED beside the currently selected charge mode will be

illuminated.

4

The charger will automatically store the selected charge mode and recall it for future charge cycles

(even after being disconnected from power).

When recondition mode is selected, the RECONDITION LED will be illuminated in addition to the

selected charge mode LED.

If required, activate low current mode (reduced charge current); depress and hold the MODE button

for 6 seconds, when activated the selected charge mode LED (normal / high / li-ion) will blink.

Depress and hold the MODE button for 6 seconds again to end low current mode.

d) When the ABS LED is illuminated the charger has moved into absorption stage (bulk stage is

complete); the battery will be approximately 80% charged (or >95% for Li-ion batteries) and may

be returned into service if required.

e) When the FLOAT LED is illuminated the charger has moved into float stage (absorption stage is

complete); the battery will be fully (100%) charged and is ready to be returned into service.

f) When the STORAGE LED is illuminated the charger has moved into storage mode (float stage is

concluded); to maintain the battery at full charge, the battery can be left on continuous charge for

an extended duration.

g) Disconnect the AC power cable from the mains power outlet at any time to stop charging.

2. Features

a) Bluetooth setup and monitoring (Using VictronConnect)

Easily setup, monitor or update the charger firmware using the VictronConnect app and a

Bluetooth enabled device (such as a mobile phone or tablet).

b) Multi-stage charge algorithm

The multi-stage charge algorithm is specifically engineered to optimise each recharge cycle and

charge maintenance over extended periods.

c) Adaptive absorption

Adaptive absorption monitors the battery’s response during initial charging and intelligently

determines the appropriate absorption duration for each individual charge cycle.

This ensures that the battery is fully recharged regardless of the discharge level or capacity and

avoids excessive time at the elevated absorption voltage (that can accelerate battery aging).

d) Temperature compensation

Charge voltage is automatically compensated depending on the ambient temperate; this ensures

that the battery is charged at the optimal charge voltage regardless of the climate and avoids the

need for manual settings adjustments.

Temperature compensation is not required and automatically disabled when in LI-ION charge

mode.

e) High efficiency

The Blue Smart Charger range is up to ~95% efficient; resulting in lower power usage, less heat

generated and cooler operation.

f) Durable and safe

i. Engineered to provide years of trouble-free and dependable operation in all usage conditions

ii. Protection against overheating: output current will be reduced if the charger temperature

increases to 50°C

iii. Protection against short circuit: If a short circuit condition is detected all status-LEDs will start

blinking

iv. Protection against reverse polarity connection: If the charger is incorrectly connected with

reverse polarity all status-LEDs will start blinking

v. Protection against ingress of dust and water/liquid

g) Silent operation

Charger operation is totally silent: there is no cooling fan or moving parts.

h) Lithium Ion compatible

Compatible with Li-ion (LiFePO₄) batteries; when the integrated LI-ION charge mode is selected

the charge cycle settings are altered to suit.

If the charger is connected to a battery where under voltage protection (UVP) has tripped, the

Blue Smart Charger range will automatically reset UVP and start charging; many other chargers

will not recognise a battery in this state.

Warning: Never charge a Li-ion battery when its temperature is below 0°C.

i) Storage stage

An additional stage to extend battery life whilst the battery is unused and on continuous charge.

j) Recondition stage

An optional stage that can partially recover/reverse lead acid battery degradation due to sulfation;

typically caused by inadequate charging or if the battery is left in a deeply discharged state.

6

k) Low current mode

An optional mode that limits the maximum charge current to a significantly reduced level;

recommended when charging lower capacity batteries with a high current charger.

l) Recovery function

The Blue Smart Charger range will attempt to recharge a severely discharged battery (even

down to 0V) with low current and then resume normal charging once the battery voltage has risen

sufficiently - many other chargers will not recognise a battery in this state.

m) Power supply mode

A specific mode to use the charger as a DC power supply; to power equipment at a constant

voltage with or without a battery connected.

3. Operation

3.1 Multi-stage charge algorithm

The Victron Blue Smart Charger range are intelligent multi-stage battery chargers, specifically

engineered to optimise each recharge cycle and charge maintenance over extended periods.

The multi-stage charge algorithm includes the individual charge stages described below:

1. Test/Charge

Before the charge cycle commences the battery is tested to determine if it will accept charge,

even if the battery is fully discharged (close to 0V open circuit voltage) it may successfully accept

charge.

The TEST LED will continue to blink until a charge pulse is able to increase the battery voltage

above 12.5V (25.0V for 24V chargers) or 2 minutes have elapsed.

If there is a clear issue such as reverse polarity connection, a short circuit or if a 12V charger is

connected to a 24V battery, the battery will be rejected, and all charge status LEDs will blink; in

this case the charger should be immediately disconnected.

If the test phase persists for an extended period and the battery casing becomes unusually hot

(after moving into bulk stage), its likely that the battery is damaged and has an developed an

internal short circuit; in this case the charger should also be immediately disconnected.

If a load is simultaneously connected while attempting to test and charge a deeply discharged

battery a false rejection may occur; in this case all loads should be disconnected, and the test

stage repeated.

2. Bulk

The battery is charged at maximum charge current until the voltage increases to the configured

absorption voltage.

The bulk stage duration is dependent on the battery’s level of discharge, the battery capacity and

the charge current.

Once the bulk stage is complete, the battery will be approximately 80% charged (or >95% for Li-

ion batteries) and may be returned into service if required.

3. Absorption

The battery is charged at the configured absorption voltage, with the charge current slowly

decreasing as the battery approaches full charge.

The absorption stage duration is adaptive and intelligently varied depending on the battery’s level

of discharge – this is determined from the duration of the bulk charge stage.

The absorption stage duration can vary between a minimum of 30 minutes, up to a maximum

limit of 8 hours (or as configured) for a deeply discharged battery.

4. Recondition

The battery is charged at low current until the voltage increases to the configured recondition

voltage.

Recondition is an optional charge stage for lead acid batteries and not recommended for

regular/cyclic use - use only if required, as unnecessary or overuse will reduce battery life due to

excessive gassing.

The higher charge voltage during recondition stage can partially recover/reverse battery

degradation due to sulfation, typically caused by inadequate charging or if the battery is left in a

deeply discharged state for an extended period (if performed in time).

8

The recondition stage may also be applied to flooded batteries occasionally to equalise individual

cell voltages and prevent acid stratification.

During recondition stage the charge current is limited to 8% of the nominal charge current, (for

example - 1.2A for a 15A charger) and the stage is terminated as soon as the battery voltage

increases to the configured recondition voltage or after a maximum duration of 1 hour (or as

configured).

5. Float

The battery voltage is maintained at the configured float voltage to prevent discharge.

Once float stage is commenced the battery is fully charged and ready for use.

The float stage duration is also adaptive and varied between 4 to 8 hours depending on the

duration of the absorption charge stage, at which point the charger determines the battery to be

in storage stage.

6. Storage

The battery voltage is maintained at the configured storage voltage, which is slightly reduced

compared to the float voltage to minimise gassing and extend battery life whilst the battery is

unused and on continuous charge.

7. Refresh

To refresh the battery and prevent slow self-discharge while in storage stage over an extended

period, a 1 hour absorption charge will automatically occur every 7 days (or as configured).

3.2 Temperature compensation

The Victron Blue Smart Charger range will automatically compensate the configured charge voltage

based on ambient temperature (unless disabled or in Li-ion mode).

The optimal charge voltage of a lead acid battery varies inversely with battery temperature;

automatic temperature-based charge voltage compensation avoids the need for special charge

voltage settings in hot or cold environments.

During power up the charger will measure its internal temperature and use that temperature as the

reference for temperature compensation, however the initial temperature measurement is limited to

25°C as it’s unknown if the charger is still warm from earlier operation.

Since the charger generates some heat during operation, the internal temperature measurement is

only used dynamically if the internal temperature measurement is considered reliable; when the

charge current has decreased to a low/negligible level and adequate time has elapsed for the

charger’s temperature to stabilise.

The configured charge voltage is related to a nominal temperature of 25°C and linear temperature

compensation occurs between the limits of 6°C and 50°C based on the default temperature

compensation coefficient of 16.2mV/°C (for 24V chargers multiply the coefficient by 2) or as

configured.

9

EN NL FR DE ES IT PT

The temperature compensation coefficient is specified in mV/°C and applies to the entire

battery/battery bank (not per battery cell).

3.3 Commencing a new charge cycle

A new charge cycle will commence when:

i. Bulk stage is complete and the current output increases to the maximum charge

current for four seconds (due to a simultaneously connected load)

ii. If re-bulk current is configured; the current output exceeds the re-bulk current in float

or storage stage for four seconds (due to a simultaneously connected load)

iii. The MODE button is pressed or a new charge mode is selected

iv. VictronConnect is used to select a new charge mode or change the function from

‘Power Supply’ to ‘Charger’ mode

v. The AC supply has been disconnected and reconnected

3.4 Estimating charge time

A lead acid battery is at approximately 80% state of charge (SoC) when the bulk charge

stage is completed.

The bulk stage duration T

bulk

can be calculated as T

bulk

= Ah / I, where I is the charge

current (excluding any loads) and Ah is the depleted battery capacity below 80% SoC.

An absorption period T

abs

of up to 8 hours may be required to fully recharge a deeply

discharged battery.

For example, the charge time of a fully discharged 100Ah battery when charged with a 10A

charger to approximately 80% SoC is T

bulk

= 100/10 = 10 hours.

Including an absorption duration of T

abs

= 8 hours

,

the total estimated charge time would be

T

total

= T

bulk

+ T

abs

= 10 + 8 = 18 hours.

A Li-ion battery is more than 95% charged at the end of the bulk stage and reaches 100%

charge after approximately 30 minutes of absorption charge.

4. Setup

4.1 Using the MODE button

There are 3 easily selectable integrated charge modes that are suitable for most common

battery types, as well as an optional recondition stage that can be included (except for Li-

ion mode).

Any settings made are stored and will not be lost when the charger is disconnected from

mains power or the battery.

a) Charge voltage

By simply selecting the appropriate charge mode for the battery type being charged,

(refer to the battery manufacturer’s recommendations) the voltage settings for each

charge stage will be altered according to the table below:

N/A

Note: For 24V chargers multiply all voltages by 2.

Charge voltage is also automatically compensated depending on ambient temperature

(except for Li-ion mode) - see section 3.2 ‘Temperature compensation’ for more

information.

The desired charge mode can be selected by briefly pressing the MODE button to

cycle through the charge modes – the LED beside the active charge mode (NORMAL /

HIGH / LI-ION) will be illuminated.

b) Recondition mode

If enabled the recondition stage is included in the charge cycle; use only if required as

a corrective/maintenance action - see section 3.1 / 4 ‘Recondition’ for more

information.

If recondition mode is enabled the RECONDITION LED will be illuminated and blink

during recondition stage.

c) Low current mode

If enabled the charge current is continuously limited to a significantly reduced level

(varies per model - refer to specifications) compared to the nominal charge current and

the cooling fan will be disabled for totally silent operation.

Low current mode is recommended when charging lower capacity batteries with a high

current charger, for example some lead acid batteries can overheat if charged with a

current that exceeds 0.3C (more than 30% of the battery capacity in Ah).

To enable low current mode, depress and hold the MODE button for 6 seconds; the

selected mode LED (normal / high / li-ion) will blink once activated.

To disable low current mode, also depress and hold the MODE button for 6 seconds.
