Problems solved by technology
The former is generally used in lead-acid battery chargers, and its disadvantages are that the power supply is bulky, bulky, and low in charging efficiency. The disadvantages of the latter are that the charging current is relatively small, and when the power is increased, it generates serious heat and the output voltage stability is poor.

Compared with the prior art, the safety charger can gain significantly improved operational stability and safety and has the advantages of reasonable structure, good operational reliability and the like.
Description
Technical field: [0001] The invention relates to the technical field of chargers, in particular to a safe charger for electric forklifts. Background technique: [0002] As a common logistics handling equipment, electric forklifts are widely used. With the advancement of battery technology, more and more electric forklifts use lithium iron phosphate batteries as energy storage components. Lithium iron phosphate batteries have many advantages that lead-acid batteries cannot match: the material is environmentally friendly and lead-free, the number of charge and discharge cycles is long, the energy density is high, and the charging rate is large, so electric forklifts need to be equipped with high-power fast chargers. [0003] Traditional chargers generally adopt two design architectures: low-frequency transformer architecture and high-frequency switching power supply architecture. The former is generally used in lead-acid battery chargers, and its disadvantages are that the p...
