How should lithium titanate battery be maintained?

Lithium titanate battery is a lithium ion secondary battery used as a cathode material for lithium ion batteries-lithium titanate, which can form 2.4 V or 1.9 V with lithium manganate, ternary material, or lithium ferric phosphate isopolar material. In addition, it can also be used as a lithium secondary battery with a positive electrode, consisting of 1.5 V with a metallic lithium or lithium alloy negative electrode. Due to the high safety, high stability, long life and green environmental protection of lithium titanate.

Predictable: Lithium titanate material will surely become a negative material for a new generation of lithium-ion batteries after 2-3 years and will be widely used in new energy vehicles, electric motorcycles, and applications that require high safety, high stability, and long cycles. field. Lithium titanate battery has a working voltage of 2.4 V and a maximum voltage of 3.0 V. The charging current is greater than 2C(ie, 2 times the battery capacity value).

Lithium titanate battery service life

The emergence of electric vehicles has virtually solved the serious problem of urban environmental pollution. In order to meet the requirements of electric vehicles for batteries, the development of batteries with high safety, high magnification performance, and a high number of cycle recharging and recharging, and long service life is both hot spots and difficulties.

In the selection of batteries, Ori Road has undergone comprehensive comparative analysis, abandoning lead-acid batteries with only 300 cycles, and ordinary lithium batteries with 800-1000 cycles, and finally choosing to recycle up to 25,000 cycles. Lithium titanate batteries.

The good or bad of the battery directly affects the driving distance and service life of the electric car.

How to maintain lithium titanate batteries

1, avoid exposure.

The high temperature will directly cause the internal pressure of the battery to increase so that the battery pressure limit valve is forced to automatically open, which will directly cause the loss of water from the battery. The consequence of excessive water loss of the battery is to cause the battery activity to decrease and accelerate the plate softening. When charging, it will cause damage such as heat, drum, and deformation of the shell.

2, when charging master charging time.

The charging time should be based on the usual frequency of use and mileage. There is a way to achieve a 15-minute charge to 90 %, even if you are ready to go out, spend another 15 minutes charging, it is OK. If the light discharge, that is, the mileage after charging is very short, the battery will soon be filled, and if the battery continues to charge, it will overcharge, causing the battery to heat up, lose water, and reduce its service life.

3, regular inspection.

If the range of electric vehicles suddenly drops by more than ten kilometers in a short period of time, it is very likely that at least one cell in the battery pack will have a broken grid, a softening of the polar plate, and a shedding of the active material of the polar plate. Once the phenomenon occurs, it should be checked, repaired or assigned to a professional battery repair agency in a timely manner.

In general, battery life can be maintained for about 3 years, and well-maintained can reach 5 years.
