Problems solved by technology

[0004] (1) For lead-acid batteries, there is no control on the output, if a short circuit occurs, the consequences will be serious
[0005] (2) There is only switch control for the lithium battery input, since the output switch is on the lithium battery, if there is a malfunction, the power output short circuit occurs, and the consequences are very serious

Abstract

The invention provides a discharge control device. The discharge control device comprises a discharge module, a power consumption module, a circuit on-off control module, a first electromagnetic switch and a processing module, wherein the circuit on-off control module is connected to one end of the discharge module and used for controlling the discharge module to begin or stop to discharge the power consumption module according to received switch-on or switch-off signal; the first electromagnetic switch comprises a first sensing component and a first magnetic component, and when the first sensing component and the first magnetic component are communicated, the first magnetic switch is at a closed state, or, the first magnetic switch is at a disconnected state; the processing module is connected to the circuit on-off control module and the first magnetic switch and used for detecting the state of the first magnetic switch and sending the switch-on or switch-off signal to the circuit on-off control module according to the state. Through the technical scheme, the safety performance of batteries can be promoted, and the personnel safety of users is ensured.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control, in particular to a discharge control device, a battery system and an electric vehicle. Background technique [0002] At present, the batteries used in electric vehicles on the market are mainly divided into two categories: lead-acid batteries and lithium batteries; for lead-acid batteries, the positive and negative interfaces of the lead-acid battery are directly connected externally, without any protection measures, and there are great potential safety hazards. If a short circuit occurs very serious. For lithium batteries, a switch is connected between the positive and negative lead wires, and the switch needs to be turned on manually for the power supply to have output. Compared with lead-acid batteries without any protection measures, the safety performance of lithium batteries has been improved, but the opening switch may malfunction. [0003] The defective of above-mention...
