Can you charge a protective board? At present, with the development of new energy ships, the lithium iron phosphate battery is applicable to a wide range of hybrid ships. Lithium iron phosphate batteries have high energy, width operating temperature range, smooth operating voltage, and long storage life. However, the lithium iron phosphate battery also exists in a harsh environment may occur in unstable problems such as fire. So, is the lithium iron phosphate battery need to be charged with a protective plate?Wuxi Huizhong is a company specializing in the production of OPZS tube-type batteries. The OPZS model is complete, the price is low, the quality is good, the after-sales service is timely, and the delivery is timely.
Case 1: The government, the county farming and poverty alleviation and development bureau in the Townsum Township, Xining City is not strong in the side of the supervision, and the implementation of the upper-level decision-making is not resolute, and it is not completely problematic. On August 10, 2017, the Central Seventh Environmental Protection Inspector Team transferred to the people's letter and visits, reflecting the water source of the water source of water source in the water source of the water source of Tasayu Village, Takamaku Township, Datong County. After investigation, the problem is true, the county party committee, county government arranges the county farming and poverty alleviation and development bureau in the same treasure huntow. Baku Township has implemented the upper-level decision-making deployment in the rectification work of the County Agriculture and Husbandry and Poverty Alleviation Development Agency, and not completely, the measures are not in place, and the rectification tasks are not completed on time, resulting in adverse effects.
What is a lithium iron phosphate battery protective board?
Lithium iron phosphate battery protective plate, as the name implies is to protect lithium batteries. The lithium battery protective plate is for it does not have excessive, overlapping, overcurrent protection, short circuit, etc., and some will also install smart chips, record the use of batteries and status.
The lithium phosphate battery protective plate is a charge and discharge protection of the serial lithium battery pack, detecting the various protection, undervoltage, overcurrent, short circuit, overall temperature state, protecting the battery life of the battery in the battery. If the battery is discharged, the protective plate will cause the electric damage to cause battery damage. This adds a layer of protection barrier to lithium batteries to make the lithium battery pack safer and extend service life. If there is no protective board, the battery life is not only affected, but also a serious situation will also occur.

Main function of lithium battery pack protection board
1) Overcharge protection
The overchaser feature refers to that when a voltage (hereinafter referred to as an overcharge detection voltage) is reached, it is forbidden to continue charging by the charger. That is, the controlled MOS tube will enter the shutdown state, and the charging is stopped.
2) Over-protection
The over-discharge protection function stops discharging the load when the voltage of the battery is lowered. The controlled MOS tube enters a shutdown state and discharges it. This process is just the opposite of the action at the time of overcharge detection.
3) Overcurrent protection
The overcurrent protection function stops the discharge of the load while consuming a large current, the purpose of this function is to protect the lithium battery pack and the MOS tube to ensure the safety of the battery in the working state. After the overcurrent detection, the battery and the load will return to the normal, and can be recharged or discharged.
4) Short circuit protection
The Huizhong lithium battery has a high-spirited characteristics of the discharge platform, high safety, long life, and excellent low temperature performance.
Control strategy for protective board system
1, working mode
The lithium phosphate battery protective plate system operates in the static mode, charging mode, and discharge mode according to the battery state. The lithium battery protective plate system is powered by external, and the system enable / shutdown is controlled by external terminals.
2, protection measures
Lithium phosphate battery protective plate system has monomer voltage overcharge, total voltage overcharge, overcurrent, high temperature, low temperature, short circuit, etc., the protection measures are as follows:
The monomer voltage or total voltage is overcharged, and the charging MOSFET is turned off when the set protection threshold is exceeded and the charging is stopped;
Charging overcurrent, when exceeding the protection threshold 15A set value 90s, turn off the charging MOSFET and stop charging;
The discharge is overcurrent, and when the protection threshold 105A set value 90s is exceeded, the discharge MOSFET is turned off and discharged;
The battery pack temperature is abnormal, when the battery pack temperature is greater than 75 ¡ã C and less than -20 ¡ã C, turn off the charge and discharge MOSFET and the battery pack stops;
The battery pack is shorted, and the charge and discharge MOSFET is turned off immediately when the instantaneous current (200A) occurs, and the battery pack stops working.
The protective plate is to protect the lithium iron phosphate battery, which does not have excessive, overlapping, short circuits, etc., and the lithium iron phosphate battery protective plate is useful, the protective plate circuit can detect the voltage of each battery in the series battery group, respectively. Current, control the charge and discharge process of the battery pack.
