Composition of battery equipment input Annual battery equipment input composition = new equipment purchase + update purchase + waste management update purchase = (P / T) * N Detailed introduction: By 2019, the market value of the biodegradable plastics industry will grow at an average annual growth rate of 13.01% to $3.477 billion. The European biodegradable plastics market is expected to grow at an average annual growth rate of 12% from 2014 to 2019.
Biodegradable plastics are mainly used in packaging, fiber, agriculture, injection molding and other fields. Among them, the packaging industry is the most widely used. In 2013, it accounted for 60% of the total market, and food packaging demand accounted for more than 70% of the Biodegradable Plastic packaging market. The market for injection molding applications is the main driver of demand for biodegradable plastics.
Our company develops a series of beauty tool products using wheat straw material, corn starch material, coffee material, wood fiber material, recycled PP material and Green PE material, and has the relevant agency certified degradable component test report.

Detailed introduction:
1. System composition The battery pack online maintenance system consists of a host, a single battery maintenance module, a battery pack total voltage transmitter, and a charge and discharge current transmitter, as shown in Figure 1. Among them, the single cell maintenance module completes the detection of the single cell voltage and temperature (optional) signals, transmits them to the host through the bus, and performs online charge and discharge maintenance on the single cells according to the commands issued by the host. There is no need to introduce many single battery voltage signal lines into the host during the construction of the project, thereby greatly reducing the hidden dangers of the system. The battery pack total voltage transmitter and the charge and discharge current transmitter are all designed to isolate, so as to ensure that all the weak current signals entering the host are safe, and further improve the safety and reliability of the entire battery system. Users can choose the type and number of modules according to their needs, and combine a variety of battery pack monitoring and maintenance systems.
Automatically record the start time of online charge / discharge maintenance and the charge / discharge capacity during the period;
Scalable online monitoring function of battery pack capacity;
240 × 64 liquid crystal display, which can display the voltage and temperature distribution curve of the monomer in real time;
Modular structure design, reduce hidden safety hazards, increase construction speed and save engineering costs;
Each host can maintain up to 128 single cells of the same group at the same time;
Provide RS232 or RS485 communication interface;
Alarms for all monitoring signals exceeding the limit, users can set alarm thresholds for various parameters by themselves;
Alarm information can be output through the communication interface, and important alarms can be output through dry contacts;
Host: 36Vdc ～ 72Vdc, 176Vac ～ 264Vac optional;
Module: 20V ~ 24Vdc (provided by the host, standby ≤ 25mA, charging ≤ 100mA);
P: price of single battery
T: The shortest service life of single battery N: The total amount of battery in use
Scrap update:
1. 48V (2V * 24 cells), one of the 2V batteries is damaged, causing the entire group of batteries to be scrapped. 2. If only one of the 2V batteries is replaced, the other 23 cells will continue to be used, which will make this group of batteries (23 cells + 1 cell) The service life is greatly shortened.
After adopting this system, the long-term battery investment shows a significant downward trend. The one-time investment of this system << Long-term (update input + waste management input)
