how to make a solar powerwall 51.2V 200AH lithium ion battery

51.2V 200AH 10KWH powerwall battery, we purchased the module PACK method of automotive grade technology:
Several advantages of using modules:
1. The automotive-grade process determines the maximum safety performance of the product.
2. The modularized PACK method is conducive to batch automated production line production.
3. Convenience of after-sales maintenance.
4. The modular structure is more for product delivery. We can prepare a small PACK 24V 200AH lithium battery module first, and a complete product only needs to be connected in series. Can be delivered quickly.

0:00 – 1:26First of all, Guangzhou Tycorun engineer with ten years of experience will present the production process which can be fully automated of lithium batteries,
You can see that our engineer are assembling the internal modules of lithium batteries. Our batteries use brand new grade A cells, Before the cells are packaged, we will test the voltage of each cell. We believe that a stable supply chain provides the best guarantee for the delivery and quality to our customers.
In the next step, we are going to spot weld the cells to connect in series and parallel for each module and equipped with a micro lens to observe the track to ensure the accuracy of each spot welding.
After that, our engineers will test voltage and resistance on it, and install sensors which responsible for the BMS(Battery Management System)

1:27-1:50 And then we are going to tied up the sensor wires in an orderly arrangement. I guess you also don’t want to see a product with a high-end appearance but a messy internal structure.

1:50-02:06 And each of our modules will have the black box design on both sides to ensure a safe distance between the module and the battery case to achieve the buffering effect.
And we also have 5kwh,7.5kwh, and 10kwh can be building with this case, it’s easy for installation. other capacity and design are customizable, Our products has been committed to opening the global market for renewable industry.

02:06-02:54 So here’s completed modules are ready for packing!

02:55-03:01Now we gonna put the modules inside the battery case,
Before the whole battery pack complete, the BMS will be installed. The BMS we use are able to support 150A discharge current, customizable heating modules, intelligent systems, and 4G which can connect with GPS.

Before connecting our modules in series inside the battery case, we will test the performance of each module, and after the connection, the total voltage of the entire battery and pre-delivery inspection will be reconfirmed.
Our engineers will do 1’til 2 times cycle tests on the battery, and adjust the inverter communication as well, high quality package is the most important projection for the battery, delivery the battery to our clients safely is our duty.

This is the assembly process of our entire 48V battery.
We introduced our production Standard Operating Procedure in the way of manual assembly for more clear, but in fact we are fully automatic production, stay tuned, we will share the fully automatic production line with you in the next video.
The most popular powerwall battery product on the market is tesla powerwall, but TYCORUN ENERGY powerwall battery 10KWH are more cost-effective than tesla powerwall, and TYCORUN ENERGY powerwall battery product technology and performance can also be comparable to tesla.
