【 Weak current College 】 battery use and maintenance of three note six skills 】

UPS battery use three note:
All UPS battery actual usable capacity and battery discharge current size, battery working environment temperature, the length of the store and load characteristics. If you cannot properly use UPS power, often cause the actual usable capacity of battery is far less than the rated nominal capacity. To do this, users must use the battery, note the following points:

1. the excessive discharge of batteries and battery long way inactive, will make the batteries inside large amounts of lead sulphate and adsorption to battery cathode to form the so-called cathode "Kraft", resulting in a battery, the battery can recharge and discharge performance is affected. Current popular M-type seal lead-acid battery life is approximately 3 to 5 years.

2. for most UPS power, when the battery every time after discharge, you can use internal charging circuit for float. In order to ensure the batteries are replaced saturated charging status, the General need of charging time of 10 to 12 hours. Charging time enough to cause the battery is in charging is not sufficient, make battery actual available capacity is far lower than the nominal capacity. In the commercial power supply voltage is lower than 200V, some UPS power has not been able to use internal charging circuit charge on the battery are saturated.

3. to ensure that the battery has a good charge and discharge characteristics, long-term inactive UPS power supply (UPS power outage 10 days above), in power use, it is a good idea to not increase the load for UPS power use built-in charging circuit on battery float 10 ~ 12 hours before use. UPS power backup for use by the user, if the UPS power back-up of long-term work in working condition, it is recommended that every other month, let UPS power inverter status work at least 2 to 3 minutes to activate the battery.

Electric vehicle battery maintenance six tips

Skills in a non-storage lack of electricity

Battery in storage is forbidden in the lack of electricity. Lack of electricity status means the battery is not charging. The lack of electricity status storage battery, very prone to sulphate, sulphuric acid, lead crystals attached to the plate, blocked the electrical charge of ion channel, resulting in insufficient battery capacity decrease. Lack of electricity State idle longer, heavier battery damage. Therefore, the battery should be inactive, the supplementary electricity per month once, it can better maintain battery health.

Skills second periodic inspection

During use, if the electric cars of the continued line mileage in a sudden drop in a short time more than 10 km, it is most likely that the battery pack in the least a battery appears broken cell, plate for softening, plate active substance loss short circuit. At this point, it is timely to professional battery repair agencies inspect, repair, or distribution group. This can extend battery life compared to maximize savings.

Tips to avoid large current discharge three

Electric cars at the start, manned, uphill, please use pedal power, try to avoid instant high current discharge. High-current discharge easily lead to lead sulfate crystals, thereby damaging the battery plates of physical performance.

Tips 4 mastering charging time

During use, according to the actual situation accurately charging time, reference usually use frequency and mileage, it is necessary to pay attention to the battery manufacturers provide capacity size specifications with matching charger performance, charge current size and other parameters hold the charging frequency. General battery charge is at night, with an average charge time in 8 hours. If on the discharge (mileage after charging is very short), the battery will soon be full, continue charging the battery overcharge phenomenon, leading to water loss, fever, lower battery life. Therefore, the battery to discharge depth is 60%-70% charge and a electric best, actually used can be converted into cycling course, according to the actual situation of the necessary charge, avoid noxious charging.

Five tips to prevent exposure

Electric vehicles are prohibited in the sun exposure. Overheating of the environment makes the battery internal pressure increases and the battery was forced to automatic opening pressure limiting valve, direct consequences are increased battery desiccation, and excessive water loss inevitably raises battery battery activity decline accelerating plates softening, charging shell fever, shell knob, deformation and other fatal injury.

Tips to avoid charging plug 6 fever

The charger output plug for loosened, surface oxidation phenomena such as will result in charging plug fever, fever too long can cause charging plug short, direct damage charger, unnecessary losses. So I found the above situation, you should promptly remove oxides or replacement patch
