Problems solved by technology

[0004] When the patrol car is on duty, the warning lights, display screens, sirens and other electrical equipment on the car must be turned on all the time. If the engine is not running at this time, the power of the car battery will be quickly consumed, which may cause the patrol car to stop again Unable to start normally due to insufficient power at startup
If the engine is not turned off for task processing, although the car generator can supply power to the car battery, it will consume fuel resources and generate a lot of noise and exhaust at the same time, resulting in energy waste and environmental pollution.

specific Embodiment

[0108] The controller detects the voltage values ​​of B1 and B2 in real time B v1 , B v2 , and with the set threshold B T1 , B T2 , B T3 , B T4 And compare between the two, control the charging and discharging process.

[0109] B1: car battery B2: new battery

[0110] B v1 =14.0VB v2 =13.0V

[0111] The initial state parameters of the controller are set as follows:

[0112] B T1 (B1 discharge minimum voltage value): 12.2V, B T2 (B2 maximum voltage value): 14.4V;

[0113] B T3 (Prompt warning voltage value): 11.5V, B T4 (B2 discharge minimum voltage value): 10.8V;

[0114] In the initial state when the patrol car is on duty and turned off, the controller detects that the voltage values ​​of B1 and B2 are B v1 =14.0V, B v2 =13.0V, B v1 (14.0V) greater than threshold B T1 (12.2V), and greater than B2 voltage value B v2 (13.0V), so B1 can charge B2. When B v1 ≤B v2 When , B1 stops charging B2, and the controller continues to detect; when B v1 Reduced to less...

Abstract

The invention discloses a power supply system used for a fuel driven patrol car. The power supply system comprises electric equipment, an electric generator, an adjuster and an automobile storage battery, and is characterized by further comprising a controller, an additional storage battery and an alarm device; two power ports of the controller are connected with the power end of the automobile storage battery and the power end of the additional storage battery respectively to form a charging loop; the power end of the additional storage battery is connected with the electric equipment through the output power port of the controller to form a discharging loop; the controller can carry out switch-off or switch-on control on the charging loop and the discharging loop respectively; and the alarm device is connected with the controller. The invention also discloses a control method of the power supply system. According to the power supply system and the control method, the energy use efficiency of the fuel driven patrol car can be improved.

Description

technical field [0001] The invention belongs to the field of power supply devices for fuel-driven patrol vehicles, and in particular relates to a power supply system for fuel-driven patrol vehicles and a control method thereof. Background technique [0002] Patrol car is a car specially designed and developed for security and peacekeeping personnel. According to the source of power, patrol cars are divided into electric drive type and fuel drive type. At present, the cruising range of electric-driven patrol vehicles is still limited by battery (capacity) technology, so they are usually used for small-scale patrols, and fuel-driven patrol vehicles are mainly used for large-scale patrols. [0003] The fuel-driven patrol car is equipped with electrical equipment such as warning lights, display screens, and sirens. The power supply system of the fuel-driven patrol car in the prior art is to electrically connect the above-mentioned electrical equipment to a car battery (car bat...
