Shanxi tower response China tower "deepening energy innovation management, vigorously carry out power battery cascade utilization", communication with government departments, cascade battery manufacturer actively, promote application of cascade batteries.

Shanxi has begin use cascade battery location advantage, the government of Shanxi Province to build "national energy revolution pioneer" for strategic positioning, taiyuan is the world's first pure electric city taxi, a taxi all the E6, for pure electric bus is gradually replaced.At present, the company on the battery's handling of the centralized processing for all batteries back to shenzhen factory, this waste of both logistics costs, and take up the factory production capacity.

Tower was established in September 2017, shanxi cascade battery application to promote working group, select stop generating frequent, peak cut scenes, photovoltaic power generation, on the whole life cycle control, to build a distributed energy management system focus on work.

One is the whole life cycle of propulsion control: based on the power battery number, to install and use the new car, retired, transportation, dismantling assembly, delivery, installation, operation, the whole life cycle control pilot, make a cascade battery use of traceability.

The second is to build a distributed energy management system: according to the monitoring and network management, statement analysis model, in the national first complete byd cascade BMS battery state - and emerging of FSU docking test and preliminary data analysis.Through the FSU device back channel base station, collection and the batteries capacity, voltage, current, charge and discharge frequency, temperature and other information.Based on the "Internet" mode, build distributed energy management system.

Three is preliminary build basic production and management ability: by cascade battery installation, tuning, familiar with cascade battery product features, installation, testing and maintenance team.Innovation in shanxi Eiffel Tower al qaeda for on-site training, four group has completed a total of more than 400 front-line staff training.

To promote business development is the important measure of tower company transformation and upgrading.Shanxi tower tower called for a positive response China, through deep aggregation of industry resources, combined with their own advantages, the implementation of industry development plan is given priority to with DaiWei power output.At present, has been in the cascade intelligent battery for electrical system, mute generators has made certain progress.

Mute generators

Mute generating services is derived from the user for the traditional oil machine electricity board's actual demand, according to the user for quiet, high quality and low cost of power generation service requirements, comprehensive shanxi tower cascade use battery ShuDeHua operational monitoring maintenance advantage, for the user needs to build integration solution to mute generators as the core.

1. Play their own advantages: shanxi tower maintenance team has achieved global coverage in the province with 7 x 24 hour uninterrupted maintenance;On the cascade battery use also received various aspects support;At the same time, introduced the first environmental cascade battery based mute electricity services.

2. Customer demand analysis: at present, the city within each big bank outlets widespread UPS performance degradation, lack electricity service, serious insufficient force to maintain itself.Traditional oil machine power noise is too big, can't meet specific scenarios, such as residential areas users) power generation requirements.

3. Build mute generators as the core of integration solution: mute generating services is derived from the user for the traditional oil machine electricity board's actual demand, according to the user for quiet, high quality and low cost of power generation service requirements, comprehensive shanxi tower cascade use battery ShuDeHua operation maintenance advantage, for the user needs to build integration solution to mute generators as the core.

Tower has been with quality at present, shanxi rural commercial bank, agricultural bank of jinzhong city signed the contract, the formal power service for the two lines a total of more than 40 branches, is expected to create nearly 40000 yuan a year for the company/car.Based on mute generation and 7 * 24 hours monitoring products, shanxi tower is continue to work with other Banks, security unit for popularization and application.
