Introduction
Thank you for choosing Sony’s energy storage module/controller.
The energy storage module comprises of lithium ion rechargeable batteries with 1.2 kWh capacity, and the controller enables a
central of multiple modules.
This manual provides information regarding safety precautions to prevent possible accidents and how to use the product.
Please read this manual carefully before use for safety and keep this manual handy for reference.
Main Features
Long life span
The battery can be expected to remain serviceable for more than 10 years, provided it is charged and discharged once in a day
at room temperature (23 deg. C).
Higher Safety
Olivine-type lithium iron phosphate batteries with excellent thermal stability and storage characteristics are used in this product.
The module also incorporates a self-monitoring function, for detection of any abnormalities in energy storage. The monitored
status can be communicated to an external controller to safely control the usage state of the battery.
Quick Charge
More than 90% of the capacity can be charged in one hour.
High Scalability
Multiple energy storage modules can be connected to the controller, and voltage and capacity can be customized according to
the intended use.

Function Overview
Controller
Connect multiple modules to the controller and control
charge/discharge current.
Controlling charge/discharge current
Control charge/discharge by communicating with a module.
Charge will stop when the charge signal output from a
module becomes low.
Charge will stop when “Over Voltage” signal output from a
module becomes low.
Discharge will stop when the discharge signal output from a
module becomes low.
LCD Display Panel
Information from a module (charge/discharge status,
voltage/current, capacity, temperature, etc.) is
communicated to the controller, and appears on the display
panel on the front of the controller.
Communication with Host
Information on a module and the controller can be
communicated to a host via the RS232C or CAN
communication terminal.
Protection against overcurrent
Provides fuse protection against overcurrent. An output
control switch is also included.
Auto-power on and auto-shut down circuit
Shuts down the system automatically after a module is
completely discharged. When an external charging voltage is
applied, the system will be powered on automatically.
Energy Storage Module
Charge and discharge control
Charge/discharge are controlled by 3 signal lines, charge,
discharge, and overvoltage.
In the following cases, the charge signal becomes low
 Maximum cell voltage exceeds specified voltage range
 Temperature exceeds specified range while charging
 Overcurrent flows while charging
 Charging completes

 Discharge a module at lower than 50A. (Note that the maximum current is limited by the maximum current of the controller.)
 The controller stops discharging when it reaches the minimum voltage.
 Charging current may be shut down by the controller when charging is almost finished.
