Embodiment 1

[0027] This embodiment provides a battery device 10, which is used to supply power to an electric forklift, and the electric forklift has a power receiving port for receiving a current of a first specification. Please refer to figure 1 , showing the principle structure of the battery device, the battery device 10 includes a battery body 101, and two sides of the battery body 101 are respectively provided with a charging port 1011 and a discharging port 1012.

[0028] At present, the battery equipment in the electric forklift uses a lead-acid battery. Since the charging current of the lead-acid battery is only 0.2C, when such a lead-acid battery is used, it generally takes a long time to perform slow charging and natural cooling before recharging. 1. Intermittent charging such as supplementary charging, long charging time will greatly reduce the efficiency of electric forklifts. Secondly, because the space on electric forklifts is basically occupied by large-capacity lead-acid b...

Embodiment 2

[0034] The present embodiment provides a kind of electric forklift 2, comprises the power receiving port 21 that receives the first specification electric current, cable wire, and connector, please refer to figure 2 , showing the principle structure of an electric forklift, the electric forklift 2 also includes a battery device 20 , a load 22 , a charging circuit 23 , and a discharging circuit 24 . The battery device 20 includes a battery body 201 . The battery device 20 includes a battery body 201 , and two sides of the battery body 201 are respectively provided with a charging port 2011 and a discharging port 2012 .

[0035] At present, the battery equipment in the electric forklift uses a lead-acid battery.

Abstract

The invention provides a battery device which is used for supplying power to an electric forklift. The electric forklift is provided with a receiving port for receiving a first specification current, and the battery device comprises a battery body which is provided with a charging port for receiving a second specification current and a discharging port for outputting the first specification current. A discharging unit is composed of the battery body and the discharging port of the battery body and connected to the receiving port through a cable of the electric forklift and a connector to provide the first specification current for a load of the electric forklift. A charging unit is composed of the battery body and the charging port of the battery body and connected to a charging machine to receive the second specification current output by the charging machine to charge the battery device. According to the battery device and the electric forklift with the battery device, the parallel structure of a charging loop and a discharging loop is adopted, so that it is guaranteed that the structure of an original electric forklift system is not changed, the charging current can be greatly improved, the charging time can be shortened, and the using efficiency of the electric forklift can be improved.

Description

technical field [0001] The invention belongs to the technical field of electric forklifts, in particular to a battery device and an electric forklift equipped with the battery device. Background technique [0002] Forklifts refer to various wheeled handling vehicles for loading and unloading, stacking, short-distance transportation, and heavy handling of palletized goods. At present, electric forklifts have been widely used in stations, airports, ports, freight yards, factories, workshops, distribution centers, distribution centers and other places, and can enter cabins, carriages, and containers for loading and unloading of palletized goods. Therefore, electric forklifts are indispensable equipment in the process of pallet transportation and container transportation. There are many types of forklifts in the market now. Electric forklifts are a kind of energy forklifts powered by electric motors and batteries as energy sources. Because electric forklifts have no pollution a...
