product description

◆ Overview
The portable ground charger is an intelligent charging product specially designed by our company for traction power batteries. It is suitable for charging liquid-open WET or closed VRLA (GEL / AGM) lead-acid batteries with a power of 700w-3kw. Widely used in electric forklifts, electric logistics vehicles, electric golf carts, electric minibuses, electric off-road vehicles, electric cruise ships, etc.
◆ Product Features
1. The single chip microcomputer automatically completes the entire charging process based on the battery (group) withstand current capability, life curve, gas evolution point and other information;
2. Ambient temperature compensation function to ensure temperature applicability under all weather conditions, and can automatically resist "overcharge" and "undercharge";
3. With pulse charging function, it can be fully charged on the premise of ensuring the best life of the battery;
4, with manual "equal charge" function;
5. The product is treated with "three-proof" paint and "dust-proof" design, which improves the operational reliability.
◆ Features
The charging process is divided into eight stages, and the size of the battery cell voltage (actually realized by judging the battery terminal voltage due to the discreteness of the battery cell voltage) is used as the basis for the judgment of the next stage. The eight-stage charging currents are 0.14C, 0.1355C, 0.1275C, 0.11C, 0.09C, 0.08C, 0.075C, 0.07C.
The judgment of whether the battery is fully charged during the charging process is an important indicator of the charger. If the battery is not fully charged and wrongly judged to be full, it will cause the battery to undercharge, otherwise it will cause the battery to overcharge. Both of these conditions will seriously affect the battery. life. Taken together, the judgment rules are as follows: timing control, voltage control (including maximum voltage, negative voltage increment, zero voltage increment, etc.), temperature control (including maximum temperature, highest temperature rise, temperature change rate, etc.), current Control, etc.
