Electric forklift lithium battery need high voltage control box

At present, the new energy industry has been developing rapidly under the strong support of national policies, and in the field of forklift trucks, the oil-to-electricity and lead-acid-to-lithium-electricity conversion has been vigorously promoted. Forklift trucks in the work process, usually in the high-power power drive operation, the design of high-voltage power distribution system and high-voltage components of the selection of a huge challenge. High-voltage power supply directly into the high-voltage distribution box according to the needs of the system distribution to the system of high-voltage electrical products, on how to ensure the safety of the entire high-voltage system and its electrical equipment, system insulation, electromagnetic interference and shielding, sealing and vibration resistance and other high requirements. High-voltage box is the high-voltage electric current distribution unit of all electric forklifts, referred to as pdu. so the high-voltage box is the core component of the power system of electric forklifts, the high-voltage box needs to be connected to other parts through the wiring harness, such as with the battery pack, the vehicle controller, integrated controller and power socket and other components connected to the high-voltage box to play an important role in the power supply and control of the power, the battery pack is the power of the heart of electric forklifts, the rational design of the battery pack and the high-voltage box. The battery pack is the power heart of the electric forklift, and the reasonable design of the battery pack and high-voltage box is the key link in the design of the electric forklift.

 

Now the high-voltage control part of the lithium battery, most of them are integrated inside the battery box or use the metal box as the shell, such a way whether it is the installation process of the product in the early stage or the maintenance in the later stage, are more difficult and troublesome. And the current high-voltage box and battery connection is mostly cable connection, due to the use of forklift trucks is very complex, after a period of time, may occur after the breakage of leakage occurs. At the same time, due to the complexity of the forklift, the metal box of the external high-voltage box, water seepage or even a short-circuit situation may occur.

 

In view of the shortcomings of the existing technology, to provide a simple structure, low cost, can easily and reliably realize the connection of the upper cover and the main case and the battery pack body, easy to collect plug-in directly with the battery pack body of the relevant connectors directly plug-in connection, no longer need to use the cable connection to simplify the structure, and at the same time to improve the connection of the waterproof and dust-proof performance, to avoid water seepage leading to short-circuit problems, and to avoid the dust to enter the main case internal The high-voltage control box of the battery for new energy vehicles improves safety and service life by avoiding dust from entering the main housing and affecting the components.
