Safest – ZRGP’s Mate (LFP) Passed the UL9540A test

/in /by

ZRGP is pleased to announce passing UL 9540A test at the cell, module, and system level, which means that Mate, ZRGP’s home energy storage system, has reached the highest international standard level in terms of safety and reliability. The passing of this test will help its business to grow globally.

 

What Is UL9540A?

Based on high standards of international certification, reliable R&D strength, and scientific technology training, ZRGP is committed to providing customers with the safest, most economical, and most efficient energy storage systems.

The UL9540A test standard is a test method proposed by UL to evaluate the spread of large-scale thermal runaway fires in electrochemical energy storage systems and has become a landmark industry standard.

In doing so, ZRGP has demonstrated that its product meets the industry’s highest standards for safety and fire prevention.

There are 4 stages in the UL9540A test method:

– CELL LEVEL TEST

At this level, UL looks at whether a cell can exhibit thermal runaway. It also checks its characteristics and flammability.

– MODULE-LEVEL TEST

In this stage, the main goal is to determine if thermal runaway propagates with the module. They will also find out the heat release and gas composition.

– UNIT-LEVEL TEST

Now they will look at the whole unit and see the following. Firstly, they find out how quickly fire spreads. Then they will look for its heat and gas release rates and other hazards.

– INSTALLATION LEVEL TEST

Lastly, they do an installation test. This is an optional test, but its goal is to determine how effective the product’s fire protection is.

ZRGP PowerBase Mate

As a ZRGP UL9540A – certified BESS home energy storage system, Mate is our most classic product, featuring a modular LV design, LFP cells, 8000 cycle life, and scalability to meet the needs of businesses and homes of all sizes.

• Between 2 to 8 battery modules can be used in a single stack to give 10.24 to 40.96kWh usable capacity;

• Up to 15 stacks can be connected in parallel to give a maximum 614.4kWh usable capacity;

• Additional modules or parallel stacks can be added at any time to increase capacity.

 

Battery Cell

ZRGP energy storage systems adopt A-Grade LFP Cells featuring high energy density, highest-level safety, longest service life. And the standardized square batteries are easy to stack and splice.

 

  • Service life: After 8000 times of charge and discharge, it can maintain no less than 80% of the battery capacity
  • High energy density: Can reach more than 135kWh/kg
  • Long service life: The service life of a single cell is up to 8000 charge-discharge cycles
  • Charge and discharge rate: Up to 2c strength
  • Safety: Even if it is forced to cause an internal short circuit or the possibility of rupture or fire is extremely low, the battery has passed the needle penetration test

The laser welding process ensures the battery connection is reliable and the module has high reliability and long service life.

 

Battery Module

Each module of PowerBase Mate system built-in BMS, and ZRGP energy storage systems are designed as a three-layer energy management system. Your battery system will get strong protection, high reliability, and long cycle life.

 

Professional BMS:

  • Temperature management: Single-cell temperature control, temperature difference control between cells balance management: maintain the consistency of related parameters between cells
  • Protection function: Overcurrent/overvoltage/undervoltage/overtemperature/communication fault protection
  • Troubleshooting: Determine the type of battery fault and handle it accordingly
  • Communication function: CAN bus, RS485

 

Aging test on lithium battery pack

The first role is conducive to the stability of the performance of the lithium battery pack. The second is to select the consistency of the lithium battery pack after aging for a period of time.
