6. Connection mode for parallel communication

 

6.1 RS485 Parallel Communication

While in RS485 parallel communication, dial-up addresses of battery module are 1,2,3,4……14,15; By this method, we can be allowed to read each data depending on battery module. Any battery other than address 0 can be connected to the host computer; FF polling mode used as consulting mode.

51.2V Battery Power Wall

Note: RS485 communication address can not be 0, the address set by the host computer is required to be the same as the battery communication address, do  not have duplicate addresses, otherwise communication  may  be affected.

6.2    Address Switch function (Only in Parallel)

7. Battery test equipment

 

7.1 Dimension Measuring Instrument

The dimension measurement shall be implemented by instruments with equal or more precision scale of 0.1mm.

7.2 Voltmeter

Standard class specified in the national standard or more sensitive class having inner impedance not less than 10 KΩ/V.

7.3 Ammeter

Standard class specified in the national standard or more sensitive class. Total external resistance including ammeter and wire is less than 0.01Ω .

7.4 Impedance Meter

Impedance shall be measured by a sinusoidal alternating current method(AC 1kHz LCR meter).

8. Standard Test Condition

Test should be conducted with new batteries within one month after shipment from our factory and the cells shall not be cycled more than five times before the test. Unless otherwise defined, test and  measurement shall  be  done  under temperature of 23±2C and  relative  humidity of less

75%.,air 86Kpa~106Kpa.

Unless otherwise defined, 30min,rest period after charge,30min,rest period after discharge.


Handling Precautions and Guideline

For Li-ion Rechargeable Batteries

Preface

This document of 'Handling Precautions and Guideline Li-ion Rechargeable Batteries' shall be applied to the battery cells manufactured by EnrSaver

Note (1)  :

The customer is requested to contact Foshan EnrSaver New Energy Technology Co., Ltd. in advance, if and when the customer needs other applications or operating conditions than those described in this document. Additional experimentation may be required to verify performance and

safety under such conditions.

Note (2)  :

Foshan  EnrSaver  New  Energy Technology Co.,  Ltd. is  not responsible for any accidents

caused by using the battery under conditions other than those specified in this specification.

Note (3)

Foshan EnrSaver New Energy Technology Co., Ltd. will inform, in a written form, the customer of improvement(s) regarding proper use and handling of the cell, if it is deemed necessary.

 

Danger!

—   Do not immerse the battery in water or allow it to get wet.

—   Do not use or store the battery near sources of heat such as a fire or heater.

—   Do not use any chargers other than those recommended by ENRSAVER.

—   Do not reverse the positive(+) and negative(-) terminals.

—   Do not connect the battery directly to wall outlets or car cigarette-lighter sockets.

—   Do not put the battery into a fire or apply direct heat to it.

—   Do not short-circuit the battery by connecting wires or other metal objects to the positive(+)

and negative(-) terminals.

—   Do not pierce the battery casing with a nail or other sharp object, break it open with a hammer,

or step on it.

—   Do not strike, throw or subject the battery to sever physical shock.

—   Do not directly solder the battery terminals.

—   Do not attempt to disassemble or modify the battery in any way.

— Do not place the battery in a microwave oven or pressurized container.

— Do not use the battery in combination with primary batteries(such as dry-cell batteries) or batteries of different capacity, type or brand.

— Do not use the battery if it gives off an odor, generates heat, becomes discolored or deformed, or appears abnormal in any way. If the battery is in use or being recharged, remove it from the device or charger immediately and discontinue use.

 

Caution!

Do not use or store the battery where is exposed to extremely hot, such as under window of a car in direct sunlight in a hot day. Otherwise, the battery may be overheated. This can also reduce battery   performance and/or shorten service life.

If the battery leaks and electrolyte gets in your eyes, do not rub them. Instead, rinse them with clean running water and immediately seek medical attention. If left as is, electrolyte can cause eye injury.
