Embodiment Construction

[0015] Lead-acid batteries and lithium iron phosphate batteries are currently the most widely used batteries in the market. Lead-acid batteries have a long history, low price, and are the most widely used, but their disadvantages are low energy density and short service life under frequent over-discharge conditions. Lithium iron phosphate battery is a new type of battery developed in recent years. The weight specific energy is three times that of lead-acid batteries, the volume specific energy is 1.5 times that of lead-acid batteries, the cycle life is three times that of lead-acid batteries, and the power density is high. But the disadvantage is that it is expensive, and the price of batteries with the same capacity is about four times that of lead-acid batteries.

[0016] According to the respective characteristics of the above storage batteries, the present invention proposes a hybrid storage battery system in which different types of storage batteries are combined in paral...

Abstract

The invention discloses a mixing accumulator system, which is composed of a lead acid accumulator (1) constituted by at least one lead acid battery and a battery pack (3) composed of at least one ferric phosphate lithium battery, wherein, the ferric phosphate lithium battery pack (3) is connected in parallel with a first balanced protection control device (4). Compared with existing products, the products of this invention can prolong the service life of the lead acid battery under adverse behavior for more than three times, and can avoid the sulfation of the lead acid battery due to undercharging. The invention not only reduces the accumulator volume and weight when various systems adopts the lead acid battery alone, to save space for storing the accumulator, but also significantly reduces the cost of single use of ferric phosphate lithium battery.

Description

technical field [0001] The invention relates to storage batteries, in particular to a hybrid storage battery system with long service life, high charging and discharging efficiency, small size and light weight. Background technique [0002] At present, in emerging markets such as India and Brazil, the communication industry is developing rapidly, and a large number of communication base stations using lead-acid batteries as backup power have been built. Due to the instability of these national power grids, frequent power outages, long power outages, and irregular power outages, the batteries are frequently discharged or even over-discharged. After discharge, the battery cannot be replenished in time, which accelerates the aging speed of the positive plate, while the negative plate forms sulfation. Frequent deep discharge and lack of timely replenishment of batteries are the most important reasons for the rapid decline in battery capacity and shortened service life. Under t...
