ups battery Wholesalers

Zhejiang Headway Communication Equipment Manufacturing Co., Ltd. is a ups battery Wholesalers.
UPS battery ripple current affects battery reliability
Ideally, in order to extend the UPS battery life, should allow the battery is always kept in the "float" charging or constant voltage charge status. This state, power state, a fully charged battery will absorb a small charger current, it is called a "floating" or "self-discharge current. Although battery manufacturers such recommendation, some UPS design (line) to the battery to withstand the additional current, called the ripple current. The ripple current is generated when the battery to the inverter, because, according to the principle of conservation of energy, the inverter must have the input DC to AC output. This battery has formed a small charge and discharge cycles, the charge and discharge current frequency is twice that of the UPS output frequency (50 or 60Hz).
Ordinary back-up, line interactive UPS will not backup / ferromagnetic-type ripple current, other designs UPS will have a size ranging from ripple current, which depends on the design method. Just check the UPS chart can know that the UPS can produce ripple current.
Battery voltage affect the battery reliability
The battery is a single "primary cells" component, each of the original battery voltage is about 2 volts, the original batteries in series to form the high voltage battery, a 12 volt battery consists of six primary batteries, 24 volt battery from 12 of the original cell and so on. UPS battery charging, each series of the original battery is charged. The original battery with a slightly different performance will lead to some of the original battery charging voltage is higher than other primary battery, this part of the battery will be premature aging. As long as the series a original battery for the elderly poor performance, the battery performance will also decline. The test proved the number of primary cells of the battery life and series related to the battery voltage is higher, the faster aging.
UPS capacity is fixed, the design should be as much as possible so that the lowest battery voltage, so that the UPS battery life longer, when the battery voltage, you should select a small number of voltage primary cells series battery, do not select the number of multi-voltage and low batteries in series battery. Some manufacturers of UPS battery voltage is relatively high, because the capacity of certain higher the voltage, the smaller the current, you can choose the smaller wires and smaller power semiconductor and thereby reducing the UPS cost. Capacity 1KVA UPS battery voltage is generally 24 ¯ 96V.
