First, the basic product information

This product is a low-voltage distribution box assembly supporting BYD single-drive lithium-battery forklift. It is the core power distribution unit of the forklift's low-voltage electrical system and belongs to conventional BYD forklift accessories. The product integrates fuse, relay and outlet wiring harness assemblies. It is developed according to the specifications of the original car single-drive model. It can replace the faulty distribution box of the original car. It is suitable for maintenance and replacement scenarios such as aging of the distribution box, internal ablation, and circuit failure.

II. Core Functions

1. Low voltage power distribution control
   

   As the general distribution node of the low-voltage circuit of the forklift, the low-voltage power of the battery is diverted to various power circuits such as instrumentation, lighting, walking system, and steering system, so as to realize the orderly power supply of the low-voltage equipment of the whole vehicle.
   

2. Circuit overload short circuit protection
   

   Built-in multi-loop fuses and control relays can quickly cut off the corresponding circuit power supply when the circuit is overloaded or short-circuited abnormally, helping to reduce the risk of back-end electrical equipment burning and protect the vehicle's low-voltage circuit.
   

3. function on-off control switching
   

   The on-off control of each power function is realized through the built-in relay, and the start-stop control of power-on, lighting and auxiliary features is completed with the vehicle key switch and function buttons.
   

4. Centralized wiring for easy maintenance
   

   The decentralized low-voltage circuits are centrally integrated and managed, and the wiring is regular, which is convenient for locating the corresponding insurance and circuits in the event of failure, reducing the difficulty of circuit investigation and maintenance.
   

III. Product technical characteristics

1. Original specification adaptation design
   

   Developed according to the original electrical standards of BYD forklift, the interface pin definition, wiring harness arrangement, and installation fixed hole positions are consistent with the original specifications. Under the normal working conditions of the corresponding model, it can be replaced and installed in situ, and generally no additional line changes are required.
   

2. integrated assembly structure
   

   Set distribution housing, fuses, relays, wiring harness in one, factory complete internal assembly and testing, assembly structure for easy replacement and installation, help to improve maintenance efficiency.
   

3. Industrial condition protection design
   

   The shell is made of flame retardant engineering material, with its own heat dissipation grille structure, and has dustproof and anti-vibration characteristics, which can adapt to the conventional operating environment of warehousing, logistics, and manufacturing workshops.
   

4. Prefabricated wiring harness is easy to plug in.
   

   Comes with prefabricated wiring harness and special plug-in connector. The connector has a anti-fool structure, clear alignment, and stable connection after connection, which helps to reduce the probability of loosening and poor contact during use.
   

IV. Adaptation range

It is suitable for BYD single-drive version 80V lithium-ion counterbalanced forklift, corresponding to conventional single-drive models such as CPD20 and CPD25. It is a commonly used electrical vulnerable replacement part in BYD accessories. It is suitable for maintenance and replacement of distribution box shell damage, internal fuse holder ablation, relay failure, internal short circuit leakage and other fault scenarios.
