Method for replacing a lithium ion battery by electric vehicle lead-acid battery

Everyone knows that the national advocacy green can continue to develop, after the introduction of the new national standard for the electric motor industry, there is a strict accordance with the various standards of electric vehicles, especially the electric car battery, more tendency to use lithium-ion batteries, means that electric vehicles Test will be more stringent. On the other hand, the company also has 3C certification and electric motorcycle qualification. In view, if the lead-acid battery of the electric car is replaced with a lithium-ion battery, it is more popular.

The lead-acid battery of the electric vehicle is replaced into a lithium-ion battery as follows: 1. Understand what battery is used by the battery used by the electric vehicle, the battery discharge capacity, the magnification (maximum discharge is); the proposed replacement lithium-ion battery is in discharge The original battery of the electric vehicle; The maximum current passed by the wire, the alert current is too large, and the electric car other electronic component electrical current is permissive, the proposed current should be smaller than the permitted current limiting value; 5, the lithium ion battery appearance size, generally The lithium-ion battery of the same capacity and discharge is much smaller than the lead-acid battery, so there is a gap in the place where the electric vehicle is placed, and the insulating material can be filled with insulating substances. The batter is loose, and the vibration is frequent or too much.

Safety accident will occur; 6 The choice of lithium-ion battery capacity, generally proposal to select the capacity of the electric vehicle. The original battery is the same. Generally, the two-fold capacity is selected, and the capacity is too much to occur.

The selection of lithium-ion battery is selected, the current electric vehicle lithium ion There are several kinds of batteries for consideration. 18650 lithium-ion battery, lithium iron phosphate ion battery and polymer lithium ion battery. In general, if the lithium ion battery cell is new, the prices of polymer lithium ion batteries are the highest, and the lithium-ion battery is secondary, and the 18650 lithium ion battery is the lowest, because the polymer lithium ion battery is in density energy ratio.

The weight is large, the weight is much larger, and the weight of the lithium iron ion battery is better in terms of safety performance. The 18650 lithium-ion battery is. So I have to see my own economy to make choices.

8. In terms of battery voltage, it is important to note that the original lead-acid battery is replaced when the lithium-ion battery is required, and the capacity can be increased, the battery is longer. Even the same capacity, lithium-ion battery life and life will be longer.

Second, pay attention to the original charger can not be charged with lithium battery, to purchase or customize special chargers separately. 9, electric vehicle lead-acid battery replacement to lithium ion battery, will battery life longer? In normal use, although the large current discharge characteristics of lithium electricity itself is a short board, it will affect the battery life, but the lithium-ion battery purchased is processed by a regular manufacturer and has a BMS management system. More than lead-acid battery.

From the perspective of the national green, the lead-acid battery is more harmful to environmental pollution, and the lithium-ion battery is relatively friendly, so the lithium-ion battery replaces the lead-acid battery is relatively large.
