1. Understand what the battery used by the electric vehicle is battery, the battery discharge capacity, the magnification (maximum discharge is how much); the proposed replacement of the lithium-ion battery is the same as the electric vehicle original battery as the electric vehicle; 2. Understand the maximum electric motor motor How much is the permission power, suggest that the lithium-ion battery discharge power should be lower than the maximum level of power of electric vehicle motor, alert motor is burn; 4.
Understand the electrical car Other electronic components electrical current limit, the proposed current should be less than the permitted current limiting value; 5, the size of the lithium ion battery, in general, the same capacity and discharge lithium ion battery is more lead acid There is a small battery, so there is a gap in the place where the electric car is placed, and the insulating material can be filled with insulating substances. The battery is loose, the vibration is frequent or too much, and the safety accident will occur; 6, the choice of lithium-ion battery capacity, generally proposed to select capacity The electric vehicle original battery is the same, generally proposes to choose two times the capacity, and the capacity is too much to occur. 7.
The selection of lithium-ion battery types, there are several types of electric vehicle lithium-ion 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.
