Guidance for Battery Systems on Board of Ships 2020
1
CHAPTER 1 GENERAL
Section 1 General
101. Application
1.
This requirements in this Chapter apply to the ships intended to be registered as ships provided
with battery systems(hereinafter referred to as "battery systems").
(2019)
2.
Items not specified in this Guidance are to be in accordance with each relevant requirement of
Rules for the Classification of Steel Ships except for the requirements inapplicable to battery sys-
tems on board of ships.
(2019)
3.
Items not included in this Guidance may comply with ISO, IEC, KS or equivalent recognized stand-
ards by the appropriate consideration of the Society.
4.
Since the battery system has different characteristics depending on the classification of the battery
being constructed, this Guidance applies when a battery system with a capacity of 50 kWh or more
using lithium secondary battery is used for the following applications.
(2019)
(1) Battery system used for main source of electrical power
(2) Battery system used for purposes other than main source of electrical power
5.
Even though the design of the battery systems deviates from those specified in this Guidance, it may be
approved after inspection if it complies with the Rules and Guidance of the Society.
102. Definitions
The definitions of terms are to follow Rules for the Classification of Steel Ships, unless otherwise
specified in this Guidance.
1.
"Battery management system" means
a device for monitoring the charge/discharge status to that the
battery can be efficiently managed by measuring the values of current, voltage, temperature, etc. and for
safely controlling the function of the battery such as operating the safety device in case of abnormal
operation.
2.
"Energy management system" means the upper management system of the battery system including
a monitoring and control system for energy capacity. When the function of the energy management
system is included in the power management system, the power management system is regarded
as an energy management system.
3.
"Electric power converter"
a device capable of both of the function of suppling power to the power sys-
tem by converting the designated DC power from the battery to AC or suppling power directly to the AC
load and the function to charge the battery by converting AC power from the power system to DC.
4.
"Lithium Secondary Battery" means
a secondary battery that stores electric energy obtained by an oxida -
tion/reduction reaction of lithium ions between an anode and a cathode.
5.
"Cell" means a component of
the smallest unit that constitutes a battery
.
6.
"Module" means
a component of a unit in which one or more cells are connected in series or in parallel.
And a module-based battery management system may be included.
7.
"Battery pack" means an energy storage device which is comprised of one or more cells or modules
electrically connected.
8.
"Battery system" means
an independently operable device connected to the battery control device and an
assembly in which one or more modules or battery packs are connected in series or in parallel. And bat-
tery system may include a power converter for charging/discharging the battery
.
9.
"Battery space" means the enclosed area where the battery is installed.
(2019)
10.
"Rated capacity" means capacity value of a cell or battery (Ah) determined under specified con-
ditions and declared by the manufacturer.
11.
"SOC (state-of-charge)" means the available capacity expressed as a percentage of rated capacity.
