Just Power® "Tank series" and "OPS series" - Standard Power Storage System for LEVs and Renewable Energy
Online, May 26, 2010 (Newswire.com) - At present, the energy storage technology is the key factor of three oncoming industries: renewable energy, electric vehicle, and smart grid. In the PV or wind-power generating, the main field of renewable energy, however, there is commonly a time gap between power generating and power loading, except of huge renewable energy devices e.g. wind power station or PV power plant. The renewable energy generating is the kind of transformation of natural energy, and it is impacted seriously by climate, weather, terrain and seasons and not pretty stable, which also impact the reliability of total system a lot. For instance, PV powered street light always has the power in the daytime, but the power loading is at night time. The wind-power station still generates the power in the low-loading period in the mid-night, but it does not generate the power in the low orographic wind, although it is in the high-loading period.
The Renewable Energy System Integrators do always not have effective solution to close the huge gap between power generating and power loading. It is the root cause of impacting the popularity of applying the renewable energy. In the global trend, however, of people and governments realizing to use renewable energy then to reduce the dependent of fossil fuels, the issues of improving power supplying quality and high-effective power storage system for renewable energy have been emphasized.
On the other hands, the total proportion of lithium battery module and BMS is approximately 50% to 60% in the total BOM cost of pure electric vehicle. Because the battery module cost is extremely high at present, it also impacts people's will to adapt electric vehicle a lot. Besides, poor infrastructures for electric vehicle charging, and lithium battery module safety issue, are the root causes of impacting the popularity of electric vehicle, too.
The secretary of US Department of Energy (DOE), Steven Chu, announced 5 directions of smart grid in US to be Renewable Integration, Energy Storage, Load Management, System Transparency, and Cyber Security and Physical Security. Among above directions, there is still no perfect solution in the high-power energy storage technology at this moment.
Finally, no matter in the electric vehicle or in the renewable energy, most of power storage devices are still sealed lead acid batteries. The sealed lead acid battery, however, is with low discharging efficiency, high pollution, short life cycle, and not green material, and makes most countries to abandon sealed lead acid battery as power storage solution in the electric vehicle and renewable energy generation. On the other hands, lithium battery, as the next generation of power storage solution, is still with huge bottleneck in the development of standard module and BMS, no matter what the cell material is.
In order to solving above listed problems, Digi-Triumph announces, with the brand name of "Just Power", "Tank S series" power storage system for PV and wind-power generation, "Tank M series" battery module for electric boats and Light Electric Vehicles (LEVs), and "OPS (outdoor power storage) series" for stand-alone device, by 7-year experience in the development of Lithium-ion battery module.
Tank S series - It is the power storage and BMS system for PV and wind-power hybrid system for telecom or wireless base station, and high-power Building Integration PV (BIPV) system. The specifications are 24V/50Ah, 100Ah, 150Ah, 200Ah; 48V/30Ah, 45Ah, 60Ah, 100Ah, with three kinds of materials: LiMn2O4, NMC, and LiFePO4.
Tank M series - For the application of electric boats and LEVs, Digi-triumph offers 5 standard modules: 24V/50Ah, 24V/100Ah, 48V/50Ah, 48V/100Ah, and 60V/50Ah. The warranty time of Tank M series is 5 year.
OPS series - It is individual power storage and status monitoring and reporting system, for stand-alone device such as LED street lamps, traffic signs, Surveillance system, smart meters, and wireless base station. We offer three specifications: 500W, 1.5KW, 3KW, at this moment. OPS is also designed with IP67 water-proof, and easy installation for System Integrator. The remote control center can get the battery module condition, charging and discharging status by RS-232 or I2C interface, which is also able to be anti-stolen and fault reporting.
Just Power "Tank Series" and "OPS Series" products are your best solution of power storage system in recycled energy generating, LEVs, and smart grid.
