  At present, floor scrubbers and sweeping robots have long become necessary cleaning equipment for property management companies. You can often see small carts or small carts. And the car wash shops and cleaning on the sales market mostly use battery-driven system software, that is, the use of lead-acid batteries is maintenance-free. And today   18650 3.7 v Battery Factory   wants to talk to you about lithium batteries. Should I choose a battery or a lithium battery for cleaning equipment? Lithium-Ion Battery 01 Charge and use Lead-acid battery has only 500 times of deep charge and deep discharge. It has battery charging memory and has a service life of about 2 years. In contrast, lithium batteries are more durable and have no battery charging memory. The cycle system frequency reaches 1500 times. up and down. The washing vehicle after charging the battery generally takes 3-4 hours, but if the cleaning area is large, and the total use time of the washing vehicle in a day...

  As an   18650 Battery Factory , share with you. The protection circuit of this lithium-ion battery consists of a protection IC and two power MOSFETs. The protection IC monitors the battery voltage and switches to an external power MOSFET in the event of overcharge and discharge. Its functions include overcharge protection, overdischarge protection and Over current/short circuit protection. 18650 Battery The principle of the overcharge protection IC is as follows: When the external charger is charging the lithium battery, in order to prevent the internal pressure from rising due to the temperature rise, the charging needs to be stopped. At this time, the protection IC needs to detect the voltage of the battery, and when it reaches (assuming the overcharge point of the battery is), it is overcharged, which turns the power MOSFET off, and then cuts off charging. In addition, you must also pay attention to the overcharge detection error caused by noise, so as not to be judged as...

  As an   18650 Battery Factory , share with you. In recent years, reference documents in various countries around the world have carried out a lot of scientific research on the embrittlement system and regularity of lithium batteries. It is widely believed that the accumulation of lithium-ion batteries, the increase in SEI film thickness and the damage of active materials are caused by the embrittlement and volume attenuation coefficient of rechargeable batteries. The key reason. The indiscriminate use of lithium batteries will accelerate the embrittlement of rechargeable batteries, and all normal charging and discharging will also endanger the physical and mental health of rechargeable batteries and accelerate the embrittlement of rechargeable batteries. Pansonic Battery 1. The harm of temperature to the SOH value of rechargeable batteries. It is generally believed that temperature is a key element that endangers battery health. Temperature has a two-way hazard to battery pe...

  As a   18650 3.7 v Battery Factory , share with you. 1. The lithium battery pack cannot be charged. The lithium battery pack in a pure electric vehicle cannot be charged when the battery is charged. The reasons can be divided into: wrong charging head or common failure of the charging head; rain shield maintenance or lithium battery protection board invalid; lithium battery pack and high-power electrical appliances Short circuit outside. 18650 Battery 3.7 V 2500mah After solving the safety hazards, we searched successively: Is the charging head connected incorrectly, whether the positive and negative power plugs of the lithium battery pack are connected incorrectly; eliminate the maintenance of the lithium battery protection board of household appliances, restart the MOS tube, and accurately Measure whether the MOS tube has the operating voltage of the driver; check whether the wiring is broken. 2. Lithium batteries cannot be discharged. The lithium battery pack in a pure el...
