When enterprises plan to push forward the lithium forklift fleet rollout project, site power supply matching is one of the core pre-construction links, which directly affects the subsequent operation efficiency, daily use cost and long-term expansion space of the whole fleet. Scientific and reasonable demand estimation of power supply upgrade can effectively avoid extra redundant investment, and also eliminate potential hidden dangers of unstable operation in the high-load stage.

First, carry out full-caliber statistics of expected charging load. You need to count the total number of forklifts to be put into operation in different phases, confirm the rated power of supporting charging facilities, and reserve 20% to 30% of the load margin for subsequent equipment expansion according to the actual peak power consumption scenario of the site. It is not advisable to only calculate the load of the charging area in isolation, and the peak power consumption data of other existing industrial equipment in the same distribution area should be fully superimposed, to avoid the risk of overload tripping during the peak period of simultaneous use of multiple equipment.

Second, complete the on-site investigation of existing power distribution facilities. Professional technicians need to check the rated capacity of the main distribution box, the aging degree of the circuit in the preset charging area, the load-bearing capacity of the cable, and the distance between the planned charging station location and the power output end. If the existing line has been used for more than 10 years or runs close to the rated load for a long time, it is necessary to make a targeted transformation plan for the line first, so as to avoid potential safety hazards such as line heating in the continuous high-load operation stage.

Third, rationally plan the peak-valley power consumption matching scheme. Combined with the actual operation rhythm of the enterprise, count the idle time period of the forklift fleet, focus on arranging the centralized charging demand in the low electricity price valley period, and evaluate whether the site needs to add supporting energy storage modules to cooperate with the operation, to reduce the overall power use cost while ensuring stable and continuous power supply.

Fourth, verify the access specification of power grid side. Communicate with the local power supply department in advance, submit the expected total load demand data of the charging facility, confirm the access conditions of the distribution network, and complete the corresponding procedures for capacity increase as required, so as to avoid the situation that the project progress is delayed due to imperfect power supply related procedures in the later stage. After completing the above steps of systematic investigation and verification, the project team can form a clear and implementable power supply upgrade plan, which can meet the stable operation demand of the lithium forklift fleet in the full life cycle, and create solid basic conditions for the efficient operation of the subsequent material handling link.
