Low-temperature lithium batteries have the advantages of small size, high specific energy, no memory, high service life of the reincarnation system, and low life rate of high-voltage rechargeable batteries and low-temperature lithium batteries. Unlike nickel-cadmium and nickel-metal hydride rechargeable batteries, low-temperature lithium batteries must take into account the insurance factor when the battery is charged, charged and discharged to avoid deterioration of characteristics.It is very important to maintain the maintenance and maintenance of low-temperature lithium batteries for moderate charging, overcharging and discharging, overcurrent and short-circuit faults. Therefore, individual maintenance routes will be designed and planned in the battery pack for the maintenance and maintenance of low-temperature lithium batteries.
Because low-temperature lithium batteries have a higher specific energy, it is necessary to ensure the insurance factor of rechargeable batteries.In the case of excessive battery charging, the kinetic energy will be excess after the battery temperature rises. Therefore, the electrolyte of the low-temperature lithium battery dissolves to produce vapor, and the risk of fire or breaking due to the increase in gas pressure; on the contrary, in the case of excessive charging and discharging, the electrolyte of the low-temperature lithium battery will cause the characteristics and utilization function of the rechargeable battery to deteriorate due to dissolution, which in turn reduces the frequency of the rechargeable battery.
The maintenance and maintenance of the low-temperature lithium battery power supply circuit is to ensure the insurance factor of such excessive battery charging and charging and discharging conditions, and to avoid deterioration of characteristics.The maintenance and maintenance power supply circuit of low-temperature lithium batteries is composed of a maintenance and maintenance IC and two output power MOSFETS. During the period, the maintenance and maintenance IC monitors the battery voltage. When there is too much battery charging and charging and discharging, it is converted to a plug-in output power MOSFET to maintain the maintenance and maintenance of rechargeable batteries. The functions of the maintenance and maintenance IC include excessive battery charging and maintenance, excessive charge and discharge maintenance and maintenance, and overcurrent/short circuit failure maintenance and maintenance.
