Battery pack

Battery pack structural features:

1.Non-framework to connect the fixed structure, effectively increasing the volume ratio of energy density;

2. Connection electrode waterproof structure, can effectively improve the contact resistance of conductive contact points caused by oxidation;

3. Elastic compensation seismic series electrical connection structure to prevent vibration environment caused by poor contact;

4.Non-welded lead structure, to avoid welding high temperature to produce the very ear electrode seal damage;

Applications :

Lithium titanate anode li-ion battery compared to traditional carbon anode li-ion battery:

Advantages of battery performance:

Compared to traditional materials "carbon negative" , the "lithium titanate anode" material for lithium-ion battery have a distinct advantage, Carbon anode lithium-ion battery has a good rate performance, but there are still some drawbacks in many aspects: Overcharge easily precipitate lithium dendrite, causing the battery to short circuit and affecting the satety performance; Easy to form the SEI film on surface of pole piece,leading to the first charge-discharge efficiency lowly, irreversible capacity large; Embedded in the lithium-ion extrusion process volume (telescopic) changes a lot, poor cycle stability.But, the lithium titanate negative li-ion battery has many advantages: Material at zero strain, cycle performance better; Stable discharge voltage; Higher lithium ion diffusion coefficient(-30°C to 55°C); Tolerance of the limit conditions, Manifested in the high technical performance from the use of lithium titanate anode nano-structured materials leading the crystallization of a variety of new technology.

Function and protection of BMS:

1.The system uses the charge / discharge side port mode;

2.To achieve the battery pack as a power-saving core overvoltage, undervoltage protection;

3.Any one energy-saving battery pack core short / open circuit, automatic ban on the battery pack charge / discharge;

4.Thermal protection in the process of charging and discharging;

5.Discharge over-current, short circuit protection function processing: protect the disconnect load recovery;

6.Real-time precision gauging: it can provide the remaining capacity (coulomb counting SOC) data transmission;

7.Intelligent resistance to the consumption charge equalization, balanced on the voltage and the equilibrium pressure difference can be software programmed equilibrium current can be designed according to actual demand. Intelligently adjusts the charging current, the battery pack balanced to achieve the best results

8.RS232 communication port for data communication;

9.All protection parameters and the corresponding delay can be programmed through the PC software to set and modify all protection parameters. The host computer can scan voltage / current is automatically saved, and real-time detection and display the protection status to facilitate the charge / discharge performance test.
