Requirements for cell identification, appearance and packaging

1. The code engraved on the top cover of the cell conforms to the code rules for cell products of our company;

2. The cell identification shall be carried out according to the standards agreed by the customer and our company (code engraving area and visual area information);

3. The packing box and packing specification shall be implemented according to the agreement between the customer and our company;

4. When the product is stored, it should be placed in the air circulation, the relative humidity is not more than 80%, and the room temperature is not more than 35 ℃,

In the warehouse which can be waterproof, anticorrosive and dustproof, the SOC state of the cell is 30 ~ 50%;

5. The packing box should be marked with the words of "handle with care", "waterproof", "anti inversion", "stackable layers", etc;

6. The packing box or box should be handled with care during transportation to avoid collision and knocking. It is strictly forbidden to mix with acid and alkali

And other corrosive items together;

7. The card board of incoming cell box is not allowed to tilt or collapse during normal shipment or placement.

 

Product end of life management

he service life of the cell is limited, and the customer should establish an effective tracking system to monitor and record each cell

The internal resistance and capacity of the cell during the service life. The measurement and calculation methods of internal resistance and capacity need the customer and the sea .We will discuss and agree with each other. When the internal resistance of the cell in use exceeds 150% of the initial internal resistance of the cell.If the capacity is less than or equal to 70% of the nominal capacity (25 ℃), the cell shall be stopped. In case of breach of this requirement, you will be exempted from Except for the product quality assurance that Haichen shall undertake according to the product business agreement and other relevant contract documents and this specification

Responsibility.

 

Application conditions

The customer shall ensure that the following cell related application conditions are strictly observed:

1. The client shall complete the warehouse in inspection within 15 days after receiving the delivered cell, and refer to the inspection specification negotiated by both parties for details;

2 working environment temperature range: charging: 0 ~ 60 ℃; Discharge: - 30 ~ 60 ℃;

3. Short term storage temperature range (within one month): - 20 ~ 45 ℃;

4. Altitude: ≤ 4500m;

5. Relative humidity: ≤ 85% RH;

6. The product will produce expansion force in the process of use. When the cell is attenuated to 70% under the test condition of 15mm steel plate, the expansion force is about 25000n. Customers need to consider the reliability of structural strength such as the system used with the cell product;

7. Customers should configure battery management system to closely monitor, manage and protect each cell;

8. The customer shall provide the detailed design scheme, system features, framework, system data, format and other relevant information of the battery management system for Haichen to assist in the design and evaluation of the system. The evaluation of aided design is a non obligatory work of our company, and the evaluation conclusions and suggestions need to be comprehensively considered by customers. If the customer fails to adopt our evaluation suggestions and has direct causal quality problems or quality accidents, our company shall be exempted from responsibility;

9. Customers are not allowed to modify the design and framework of the battery management system that has been evaluated and finalized, so as not to affect the performance of the battery cell; The customer should keep the complete monitoring data of cell operation, which can be used as a reference for the division of product quality responsibility.

If the battery system does not have complete monitoring data within its service life, our company will not undertake the responsibility of product quality assurance;

The battery management system needs to meet the following basic detection and control requirements.

 

Security precautions

1 Do not immerse the cell in water.

2. Incorrect use and storage of the cell may cause fire, explosion and burn. Do not decompose, crush, incinerate, heat or put the cell into fire.

3 it is forbidden to put the cell into the fire or expose it to the high temperature environment exceeding the temperature conditions specified in the specification for a long time, otherwise it may cause fire. Under any normal use condition, the cell temperature shall not exceed 60 ℃. If the cell temperature in the cell exceeds 60 ℃, the battery management system shall shut down the cell and stop the cell operation.

4 put the battery cell out of the reach of children. Do not remove the original package of the battery cell before use. Dispose of the waste battery cell in time according to the local recycling or waste regulations.

Do not disassemble, dismantle or repair the cell in any way without authorization.

6. Do not mix different types and brands of lithium-ion cells.

7. If the cell has peculiar smell, heat, deformation, discoloration or any other abnormal phenomenon, it shall not be used and the cell shall be transferred to a safe location.

It is forbidden to short circuit the positive and negative poles of the cell, otherwise strong current and high temperature may cause personal injury or fire. As the positive and negative poles of the cell are exposed in the plastic protective sleeve, sufficient safety protection should be provided during the assembly and connection of the battery system to avoid short circuit.

9. Connect the positive and negative electrodes of the cell in strict accordance with the label and instructions. Reverse or series charging is prohibited.

It is forbidden to overcharge the cell, otherwise it may cause overheating and fire accidents. In the installation and use of the cell, the hardware and software need to implement multiple overcharge failure protection.
