1 Caution/warning statements

1.1 General safety signs

Symbol

Meaning

Prohibition symbols are circular, showing a

black pictogram on a white background

surrounded by a red edge with a crossbar.

Warning signs are triangular, showing a black

symbol and edge on a yellow background.

Environmental regulations are information on

statutory requirements, which have to be

complied with, especially during disposal.

1.2 General hazard sources

If the following instructions for handling the device are not observed, this might lead to personal injury

or damage to the battery or your device, for which VARTA Storage GmbH will accept no liability.

a. Danger of electrical voltage

WARNING

Contact with electrical voltage!

Risk of fatal injury from electric shock!

Keep the module always sealed.

Pay attention to any damage of electrical

equipment! Eliminate defects immediately!

Don´t open the module.

Don’t connect the modules in serial only in

parallel.

Don´t connect the module or charger in reverse

polarity.

You are not allowed to disconnect the module in

active mode. Hot-plugging or hot-swapping is not

allowed in active mode! There is a risk of short

circuit between the battery modules. Only in shut-

down mode old or damaged modules can be

replaced with new modules. Even modules with

new cell chemistries are supported if available in

the future.

b. Danger from water

WARNING

Entry of water or other liquids into the module!

Possible mortal danger and material damage!

Do not use water for cleaning the module.

Never put down containers with fluids (beverage

containers and the like) on electrical systems.

The relative humidity inside the room must not

exceed 85%.

Do not clean the system with agents containing

acid, lye or solvents.

c. Danger from heat

ATTENTION

Insufficient ventilation of the system!

Overheating of the system possible!

Keep the ventilation openings clear.

Ensure sufficient ventilation.

ATTENTION

Heat input due to direct sunlight or devices emitting

heat!

Overheating and damage of the system possible!

Protect the system against direct sunlight.

Do not use fan heaters or the like near the

module.

1.3 Safety Overview on Battery Management System (BMS)

The battery contains three levels of safety, which is controlled by the BMS.

1st Level Protection for over voltage/ under voltage / over current / short circuit / over temperature /

under temperature. It is controlled by the BMS software and is non-permanent.

2nd Level Protection for over voltage/ under voltage / over current / short circuit / over temperature/

under temperature. It is controlled by the BMS software and is permanent.

3rd Level Protection (passive) with current fuse on board.

1.4 Certification

The battery is qualified acc. to UN Recommendations on the Transportation of Dangerous Goods, UN

Manual of Test and Criteria, Part III, subsection 38.3 (ST/SG/AC.10/11/Rev. 5). The battery is qualified

acc. to IEC 62133-2:2017.

3 Introduction of ASB

Application Specific Batteries (ASB) is VARTA’s new range of lithium-rechargeable battery products

from VARTA Storage GmbH, offering products in the voltage range of 24V –48V for modern systems

and applications.

We offer a growing range of battery packs that are immediately available for high-energy or high-

power applications. All ASB battery packs are fitted with an electronic battery management system

(BMS) with protection against unsafe conditions. All cells used comply with the requirements of the

safety standard UL1642 and the packs in this handbook are certified to additional safety standard

IEC62133-2:2017 as well as UN38.3 requirements for transportation.

SYSTEM HIGHLIGHTS OF VARTA STORAGE ASB RANGE:

►Excellent energy density

►Zero maintenance requirements

►Different form factors

►Low self-discharge and wide temperature

range

►~24V and ~48V versions

►Up to 40kWh systems using modular

approach

►IEC62133-2:2017 certification

►Mechanical stacking/locking design

►CAN Bus Communications (CANopen)

Comparison of different rechargeable battery systems regarding their energy densities

3.1 Definitions and Standards

BASICS

Unless otherwise stated the technical values and definitions are based on room temperature

conditions (RT = 22°C ± 3°C).

VOLTAGE DEFINITIONS

Open Circuit Voltage (OCV):

is the difference of electrical potential between

two terminals of a device when disconnected from

any circuit, dependent on battery model,

temperature, storage duration and state of

charge.

End of Discharge Voltage (EoD):

The voltage at the end of discharging depending

on discharge rate and temperature.

End of Charge Voltage (EoC) should also be

referenced from the individual specifications.

CAPACITY DEFINITIONS

The capacity C of a cell is defined by the

discharge current I and the discharge

time t: C = I * t

I = constant discharge current

t = duration from the beginning of discharge until

the end of discharge voltage is reached

Nominal Capacity: The nominal capacity C

denotes the capacity amount in Ah (Ampère

hours) that the battery can deliver at the 5h

discharge rate (0.2 C). The reference

temperature is +22°C ± 3°C, if not otherwise

stated and the final discharge voltage will also be

stated.

Available Capacity:

Factors which affect the available capacity are:

►Rate of discharge

►End of discharge voltage

►Ambient temperature

►State of charge

►Battery age

►Cycle history of the battery

At higher than usual discharge rates the

available capacity is accordingly reduced.

CURRENT DEFINITIONS

Charge and discharge rates may be given as

multiples of the Rated Capacity (C) in Ampères

(A) with the term C.

Example:

Rated Capacity C = 1000 mAh

0.1 C = 100 mA, 1 CA = 1000 mA

Nominal Discharge Current:

The nominal discharge current of an ASB battery

is the 5 hour discharge current (0.2 C). It is the

current at which the nominal capacity of a cell is

discharged in 5 hours.

I = C/t = C/5 = 0.2 C when t = 5 h

3.2 General Design and Application Criteria

Choose the best suitable battery from our range of ASB batteries according to your needs relating to

the specific application and its corresponding planned operation conditions:

The most important criteria for the type-selection are these:

►Required minimum operating time

►Charging rates required vs. calendar life target

►Max. and average current drain

►Min. and max. voltage of operation

►Operating temperature range

►Mechanical properties

►Available space

►Environmental conditions

All ASB batteries are equipped with our specially selected and carefully designed safety electronic

modules (BMS) which prevent the risks of hazards due to any foreseeable abuse / misuse.

Nevertheless, it is required that any application is designed so that the battery may operate within its

normal specification without the safety features being triggered by end-user behavior.

3.3 Features

VARTA Storage ASB batteries are first choice for a number of modern high-tech products in fields

such as robotics, Automated Guided Vehicles (AGV), related Logistics and Agricultural solutions and

more. They provide long lasting, reliable main power, occupying a minimum of space and weight in the

corresponding devices.

VARTA Storage ASB batteries fulfill the most important design-in requirements: Reliable high-power

output, design flexibility with minimized space requirements and a long life.
