Forklift battery system

Abstract

A forklift battery system disclosed by the present invention comprises a BMS mainboard, a charging control + end of the BMS mainboard is connected with a coil charging control + end of a charging relay, and a charging control-end of the BMS mainboard is connected with a coil charging control-end of the charging relay and is connected in parallel with a coil discharging control-end of a discharging relay, a coil discharge control + end of the discharge relay is connected with a discharge control + end of the BMS mainboard. The system is scientific and reasonable in structure and safe and convenient to use, a charging port and a discharging port are completely independent, charging and discharging interlocking is achieved, adhesion of the discharging relay is prevented, a discharging pre-charging loop is designed, over-discharging of a battery system is prevented, an over-discharging protection loop is designed, and a charging heating loop is adopted, so that the temperature can be kept constant.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a forklift battery system. Background technique [0002] The storage battery is one of the most widely used batteries. Use a glass tank or plastic tank, fill it with sulfuric acid, insert two lead plates, one is connected to the positive pole of the charger, and the other is connected to the negative pole of the charger. A battery is formed, and there is a voltage of 2 volts between its positive and negative poles. The advantage of the battery is that it can be used repeatedly. In addition, because of its extremely small internal resistance, it can provide a large current. Use it to power the car. The engine supplies power, and the instantaneous current can reach more than 20 amperes. When the battery is charged, the electric energy is stored, and when it is discharged, the chemical energy is converted into electrical energy; [0003] However, there is no unified ...
