As the name suggests, the battery protection board is mainly directed against rechargeable (generally refers to lithium batteries) the protective role of the integrated circuit board. Lithium battery (rechargeable type) so in need of protection, is determined by its own characteristics. As the lithium Dell inspiron 6400 battery material itself determines it can not be over-charge, over discharge, over current, short circuit and ultra-high-temperature charge and discharge, the lithium battery lithium battery components to bring the Federation along with a sample letter to Czech resistance than the protection plate and a current insurance device appears.
Li-ion battery protection function normally to protect circuit boards and current devices such as PTC, or TCO jointly undertaken and completed, protecting electronic circuit board is composed of the -40 ? to +85 ? environment, time and accurate monitoring of voltage and charge batteries back into the path of current, real-time control current loop off; PTC or TCO in high-temperature environment, bad place to prevent damage to the battery.
Protection panels usually include control IC, MOS switches, JEPSUN Czech Republic than the letter of precision resistors and auxiliary devices NTC, ID memory, PCB and so on. Which control the IC, in all normal circumstances, the control of MOS switch turn-on, so that batteries communicate with the external circuit, and when the batteries voltage or loop current exceeds the set value, it immediately (tens of milliseconds) controls the MOS switch turn-off to protect the safety of batteries.
NTC is the acronym for Negative temperature coefficient, which means that a negative temperature coefficient, the ambient temperature rises, its resistance to reduce the use of electrical equipment or a timely response to the charging device, control, stop charging and discharging of internal disruption.
ID memory, often as a single interface, memory, ID is the Identification of the acronym that is the meaning of identification, storage Dell latitude d620 battery type, production date and other information. Can play the product traceability and application restrictions.
PTC is the English abbreviation of Positive Temperature Coefficient, which means positive temperature coefficient. Professional inside positive temperature coefficient device is usually referred to as PTC, where PTC battery products can prevent the battery temperature of the high current discharge and the occurrence of unsafe, according to the battery voltage, current density characteristics and application environment, PTC have specialized requirements.
PTC is a battery component products where a very important component of the battery responsible for the security of an important mission, its own performance and quality is also a battery pack performance and quality is an important factor.
Protection plate on a single core Power adapter protection, protection board design would be relatively simple, highly technical part is that, for example on the Power adapter battery protection board design platform for issues to note the voltage, Power adapter batteries in use are often required a great platform for voltage Therefore, as far as possible designed to protect boards protect the board does not affect the discharge voltage of batteries, so that the control IC, the requirements of precision resistors and other components will be very high, the general domestic IC can meet the requirements of most products, special imported products can be used, current sampling resistor you need to use JEPSUN Czech resistance than the letter in order to meet the high-precision, low temperature coefficient, no flu demands. Protection of multi-plate design Dell inspiron 1520 battery, there are higher technical requirements, according to different needs, design complexity of different products.
Main technical features:
1, overcharge protection 2, over-discharge protection
