MG’s battery factory runs on solar energy

Here, at MG, we’re passionate about energy and making the transition to an economy run on fossil-free fuels. As we strive to be forerunners in the field of storage solutions, we put our money where our mouth is. Last weekend we’ve installed 360 solar panels on the roof to power our entire battery factory.

Grid stability

Due to the growing number of solar parks and wind turbines on one hand, and a surge in electric transportation on the other, the grid is increasingly taxed with extremes in supply and demand. One moment there’s a steady surplus, the next a sudden shortage. These fluctuations will only intensify, resulting in more frequent power cuts.

Local storage

However, these peaks can be easily accommodated by local power storage. At MG Energy Systems we’re anticipating the future by developing energy storage solutions based on Lithium-Ion batteries, complemented with built in management systems to charge and discharge with extreme efficiency. Powerful enough to run our factory.

Solar panels

We chose solar panels with a very high efficiency, using the latest MWT technology (Metal Wrap Through) co-developed by

Eurotron. This technology reduces the risk of microcracks by not soldering the solar cells but gluing them, thereby ensuing a higher yield over the lifetime, compared to traditional solar panels.

Energy yield

The annual output of this installation accounts for approximately 100,000 kWh of energy. The performance is accurately tracked by means of absolute irradiation measurement with a pyranometer and the energy yield of the panels. All data are collected in the cloud and can be accessed via the MG Energy Portal, a modular web platform developed by us to monitor energy systems.

Carbon footprint

The power generated will primarily be used for all assembly and development processes in our battery factory. In addition, all five of our electric cars are being charged with solar energy to make sure we travel fossil free. Due to these measures the carbon footprint of our company and our products is relatively small.

Energy storage

The energy storage system, installed in combination with the solar panels, can be used for various applications, such as peak-shaving, grid frequency stabilisation (FCR), backup and self-consumption, each with its own business case. As most of these meet our own needs and demands, it’s a perfect impetus for further exploration.

MG Energy LAB

The solar panels and storage installation are part of the Energy LAB that was set up at MG Energy Systems, as a playground for innovation and development. For example, solar panels, storage systems and charging infrastructure for electric cars are combined, developed and tested. We consider the Energy LAB as a platform to develop energy systems of the future.

Ultimate test

Always eager to put our systems to the test, we’re excited to announce we’ve found the perfect challenge.

MG powers sustainable party & meeting venue

When event venue Pollepleats was expanded with wellness facilities, its network connection was no longer sufficient. Instead it chose to focus on the future and rely on its own sustainable power supply. With an MG energy system it’s nearly 100% energy neutral. Ready to party on renewable power.

MG powers first Mexican electric public service bus

Fighting pollution in Mexico

With high levels of pollution in most of Mexican cities, zero emission vehicles are the only way to make a difference, according to industrial designer Alfonso Hernandez. Automotive industry is shifting toward electrification, but when this only concerns new vehicles, it can take decades to clear the air. That’s why Hernandez took it upon himself to help Mexico take the first big step to clean public transportation.

Converting old buses into all-electric vehicles

His company APV international is dedicated towards exploring the opportunities of renewable energy, by turning old combustion engine buses into all-electric vehicles, thereby reducing emission to zero and saving up to 80% in costs. As a proof of concept, Hernandez took on the challenge to convert a 13-year-old diesel-powered public transport bus.

Lithium-ion in stead of lead acid batteries

Ten months ago we received a phone call from Mexico. Hernandez and his team had managed to build complete their prototype and were testing it at the moment. They used a big lead acid battery bank to power the 250 kW electric motor from TM4. They knew this wasn’t the best solution, due to the large volume, high weight, short lifetime and poor performance. What they needed was a lithium-ion battery solution that could seamlessly be integrated in the test bus.

The system

To be more precise: that meant 700 VDC voltage and a capacity of approximately 85 kWh. We provided an 84 kWh Lithium-Ion battery system with liquid cooling, consisting of 48 battery modules. Each has its own slave BMS and is connected to a MG Master HV 800V/600A that makes up the main BMS of the battery system.

On the one hand, the MG Master HV communicates with all battery modules and monitors their values. At the other side it communicates with the vehicle CAN-Bus, which consists of an advanced color display and the TM4 Neuro vehicle controller. We adjusted the CAN-Bus communication protocol to speak the same language as the TM4 Neuro. This makes the integration of the different systems even more simple.

The first

We are proud to have contributed to developing Mexico’s first public service battery bus.

We challenged ourselves with the toughest goal, knowing that once achieved, any other project would be downhill. That’s why we developed our prototype with the strongest system we could think of. This opens roads for future markets like cargo transport in short range. This way we can start moving faster towards a cleaner transport solution where everybody wins.
