Phenomenon of excessive voltage: The electric forklift voltage will cause the main contactor to be discouraged or the main contactor is bounce quickly, sometimes because there is a single battery failure within the electric forklift battery group or the battery wiring Terminal corrosion causes a poor contact.
The electric forklift has an undervoltage protection function to prevent the battery excess discharge of the electric forklift. The undervoltage protection function is an undervoltage alarm of the controller when the electric forklift is in depth discharge. At this time, the forklift should be suppleeded, when depth discharge When generated, the protective function of the forklift is started, first of all, the lifting motor of the forklift will be restricted, but the walking motor can still work properly, so it is necessary to open the forklift to the charging room.
Electric forklift excessive discharge on the battery life of the forklift is quite large, severe over-discharge can even result in the battery scrap, the undervoltage protection function of the electric forklift effectively extends the life of the battery pack.
