Tesla mega pack battery - powering the megapack with efficiency
Maybe you’ve also heard of the Tesla megapack? But do you know that there are details about tesla mega pack battery?As one of the top 10 powerwall manufacturers for home energy storage in the world, TESLA’s performance in large-scale energy storage is also outstanding.
In this article, we will introduce the tesla mega pack battery in detail and explain how it powers the megapack with efficiency.
What is tesla megapack?
Megapack is a commercial energy storage battery launched by Tesla in July 2019. Each Megapack unit can store 3 megawatt hours of energy, which can meet the electricity demand of 3,600 households for one hour.
The following is the specific data of megapack:
Megapack is not only a lithium battery pack, it also integrates cables, electrical systems, thermal management systems, etc. These components are arranged together in a white casing, which is fully assembled when shipped, and can be installed within a few hours after the unit is shipped to its destination.
Megapack is currently used in some public utility projects and large enterprises. Megapack has provided power supplement and guarantee in North America, Asia Pacific, Europe and many other places. According to Tesla’s official website, the total installed capacity of Megapack globally exceeds 5 GWh.
Internal structure of tesla mega pack battery
The Tesla mega pack battery is an incredibly efficient battery that is designed to provide power supplement and guarantee for large public utility projects and enterprises. Next we will introduce the internal structure of the tesla megapack battery in detail.
The tesla megapack battery module has four layers, and the lower three layers are used to install square aluminum shell LFP batteries and liquid cooling tubes. The liquid cooling tubes are arranged in a harmonica tube type against the side of the prismatic battery.
The internal grouping of the tesla megapack battery module is made into a CTC. The total positive and negative leads from the battery series are directly connected to the B+ and B- of the fourth-layer PCS module.
After PCS inverter output three-phase 480V AC. The relevant components of the PCS are installed on the PCB, and the heat-generating components are liquid-cooled to dissipate heat.
Three U/V/W copper bars are drawn from the upper part of the back of the module of the tesla megapack battery.
When the battery module is assembled and pushed into the rack of the cabin, the AC three-phase copper bars led by the battery module are inserted into the three-phase copper bar connection sockets arranged in parallel on the back of the cabin by blind insertion.
In this way, 24 battery modules can be connected in parallel to output 480V AC. After AC confluence, the copper bars are connected to the AC frame circuit breaker.
Advantages of tesla mega pack battery
The efficient operation of the Tesla megapack is inseparable from the support of the Tesla mega pack battery.
The following are the advantages of Tesla mega pack battery:
With the highly automated manufacturing process and the ability to design extremely simplified system architectures, the charge-discharge conversion efficiency of the tesla mega pack battery can reach as high as 92%.
In terms of price and cost, the tesla mega pack battery is produced and assembled in the Megafactory. Tesla purchases relevant raw materials and assembles them on the factory’s automated production line.Therefore, it is possible to control the price and cost.
The proportion of self-made devices is high, the degree of automation of the production line is high, and the production efficiency and quality are high. Assembly of several major components into a whole product is completed on the production line in the factory.
Flexibility is a major feature of the tesla mega pack battery. It can be integrated and installed with battery modules, inverters and temperature systems at any time, helping the grid to be more stable and sustainable.
At the design level, Tesla has matched exclusive inverters for each battery module. Each unit like powerwall battery has also undergone a large number of battery tests, including integrated safety systems, professional monitoring software, etc.
In addition, the Megapack battery can also be updated in real time through OTA to continuously optimize its functions.
Tesla mega pack battery price
Since the Tesla Megapack battery is not sold separately, the following is the reference price of the Tesla Megapack.
At the same time, the price of the Tesla Megapack in different states is slightly different. The following will use the Tesla Megapack in California as a reference:
| Megapack Quantity | Megapack Duration | Include Installation | Estimated Price | Power | Energy |
|---|---|---|---|---|---|
| 1 | 2 hours | yes | $2,669,050 | 1.9 MW | 3.9 MWh |
| 1 | 2 hours | no | $1,879,840 | 1.9 MW | 3.9 MWh |
| 2 | 2 hours | yes | $5,240,330 | 3.9 MW | 7.7 MWh |
| 2 | 2 hours | no | $3,725,040 | 3.9 MW | 7.7 MWh |
| 2 | 4 hours | yes | $4,358,030 | 2 MW | 7.8 MWh |
| 2 | 4 hours | no | $3,517,580 | 2 MW | 7.8 MWh |
From the table, we can conclude that including installation in a Megapack order increases the estimated price.
For a single Megapack, the difference in price with and without installation is approximately $790,000. The price difference increases as the number of Megapacks ordered increases.
Another observation from the table is that the duration of the Megapack affects the estimated price. The estimated price of a Megapack with a duration of 4 hours is lower than the estimated price of a Megapack with a duration of 2 hours.
Finally, the power and energy capacity of a Megapack is proportional to the number of Megapacks ordered. As the number of Megapacks increases, so does the power and energy capacity.
Comparison between tesla mega pack battery and Gridstack
Gridstack is Fluence’s sixth-generation Gridstack modular energy storage product, and Tesla Megapack is an energy storage system designed for commercial and industrial use.
Next, we will compare the similarities and differences between the two, so that readers can learn more about tesla megapack battery.
Similarities
● Both systems use lithium-ion batteries for energy storage.
● They all adopt modular design, easy to expand and expand.
● Both systems are designed to be compatible with solar and other renewable energy sources.
● They are all intended for grid stabilization, peak shaving and energy arbitrage.
Difference
● Gridstack specification has higher power output per module (250 kW) compared to Tesla Megapack (180 kW).
● Tesla Megapack has higher energy capacity per module (3 MWh) compared to Gridstack (2 MWh).
● Tesla Megapack has a wider operating temperature range (-30°C to 50°C) than Gridstack (-30°C to 45°C).
● Gridstack technical specifications use an air cooling system, while the Tesla Megapack uses a liquid cooling system.
Overall, both energy storage systems have their advantages and disadvantages, and the choice between the two will depend on the specific needs and requirements of the user.
