Lithium iron phosphate battery pack protection plate useful necessary.
The protection board circuit can detect the voltage and current of each cell in the series-connected battery pack separately, and control the charging and discharging process of the battery pack. When the voltage of each cell in the battery pack is between the overcharge detection voltage and the overdischarge detection voltage, and the output is not short-circuited, the MOS tube conducts, and the P+ and P- output the battery pack voltage, allowing the battery pack to carry out charging and discharging operations.
Additionally, the protection board has the functions of battery pack over-discharge protection, over-charging protection, over-current protection, and short-circuit protection.
Extended information:
Lithium iron phosphate batteries are mainly used in the production of lithium batteries. p>Lithium iron phosphate battery main application areas are:
Large electric vehicles: buses, electric cars, attractions tour buses and hybrid vehicles, etc.;
Light electric vehicles: electric bicycles, golf carts, small flat battery trucks, forklifts, cleaning trucks, electric wheelchairs, etc.;
Electric tools: drills, saws, lawnmowers, etc.;
Remote control cars, boats, airplanes and other toys;
Solar and wind power energy storage devices;
UPS and emergency lights, warning lights and mining lights (the best safety);
Replacement of 3V disposable lithium batteries and 9V nickel-cadmium or nickel-metal hydride rechargeable batteries in cameras (exact same size);
Small medical instruments and equipment, and portable apparatus and instruments, and so on.
Here is an application example of replacing lead-acid batteries with lithium iron phosphate power batteries. Using 36V/10Ah (360Wh) lead-acid batteries, which weighs 12kg, can travel about 50km on a single charge, with about 100 recharges and a usage time of about 1 year.
If the lithium iron phosphate power battery is used, using the same 360Wh energy (composed of 12 10Ah batteries in series), its weight is about 4kg, and it can walk about 80km on one charge, with up to 1,000 recharges, and a service life of about 3 to 5 years.
While it is said that the price of lithium iron phosphate power batteries is much higher than lead-acid batteries, the total economic effect is still better to use lithium iron phosphate power batteries, and lighter in use.
