Abstract

The invention discloses an electrical control system for a lithium battery of a special vehicle. The electrical control system comprises a lithium battery module (7), a BMS management system (5), a heating unit (6), a direct-current contactor (3), a shunt (2), a fuse (1), a pre-charging resistor (10), a DC / DC (4), a shunt release (9) and a DC circuit breaker (8), the lithium battery module (7) converts voltage through the DC / DC (4); and after the shunt release (9) monitors that the total voltage or the monomer voltage is lower than a control threshold value through the BMS management system (5), the DC circuit breaker (8) on the DC / DC (4) line is disconnected, so that the DC / DC (4) is in an open-circuit mode and stops working. The DC / DC (4) is matched with the DC circuit breaker (8) containing the shunt release (9) for use, the purpose of replacing a lead-acid storage battery can be achieved, and the advantages that the manufacturing cost is reduced, and the compactness and the light weight of a vehicle are reflected are achieved.

Description

technical field [0001] The invention relates to the technical field of electrical control of a lithium battery system of a new energy vehicle, in particular to an electrical control system of a lithium battery of a special vehicle and its working mode. Background technique [0002] Existing new energy vehicles, as environmentally friendly models, are welcomed by the government and consumers. However, in conventional lithium battery electrical control systems for new energy vehicles, 12V or 24V lead-acid batteries are generally used as the power supply for the BMS management system. Lead-acid batteries not only increase the manufacturing cost of the lithium battery system, but also occupy the space of the vehicle, which has a certain degree of impact on the compactness and light weight of the vehicle design. Contents of the invention [0003] In view of this, the present invention provides a lithium battery electrical control system for special vehicles, including a lithiu...
