Embodiment 1

[0072] Example 1: Restricted conditions: the monitoring time of the internal temperature sensor and the electricity monitor is 11:00, 12:00, 13:00, 14:00, 15:00, and the temperature collected by the internal temperature sensor is 22 ℃, 23.1℃, 24.5℃, 24.9℃, 25℃, the battery power is 95.6Q, 94Q, 89Q, 87.3Q, 85Q, extract the maximum value of the internal temperature sensor temperature of 25℃ and the minimum value of 22℃, extract the The maximum value of the monitored power is 95.6Q and the minimum value is 85Q, according to the formula:

[0073]

[0074] Calculated:

[0075]

[0076] Therefore, the calculated temperature collected by the internal temperature sensor and the power monitored by the power monitor satisfy the above formulas, and the central control management module defaults the battery temperature and power consumption to a normal state, and sends the measurement data of the internal temperature sensor to the battery temperature control module After temperatur...

Embodiment 2

[0077] Example 2: Restricted conditions: the monitoring time of the internal temperature sensor and the electricity monitor is 8:00, 9:30, 10:00, 11:30, 12:00, and the temperature collected by the internal temperature sensor is 35 ℃, 34.1℃, 25.3℃, 22.9℃, 20.3℃, the battery power is 98.7Q, 87Q, 79.1Q, 63.5Q, 51Q, extract the maximum value of the internal temperature sensor temperature 35℃ and the minimum value 20.3℃, extract the gas monitor The maximum value of the monitored electricity is 98.7Q and the minimum value is 51Q, according to the formula:

[0078]

[0079] Calculated:

[0080]

[0081] Therefore, the calculated temperature collected by the internal temperature sensor and the power monitored by the power monitor do not meet the above formulas, and the central control management module determines that the battery temperature and power consumption are abnormal, and sends the measurement data of the internal temperature sensor to the battery temperature control. ...

[0082] Example 3: Restricted conditions: the monitoring time of the internal temperature sensor and the electricity monitor is 8:00, 11:00, 14:00, 17:00, 20:00, and the temperature collected by the internal temperature sensor is 20.2 ℃, 22.3℃, 23.8℃, 28℃, 32.7℃, the battery power is 87Q, 81Q, 72.5Q, 61.3Q, 49.7Q, extract the maximum value of the internal temperature sensor temperature 32.7℃ and the minimum value 20.2℃, extract the power monitor The maximum value of the monitored electricity is 83Q and the minimum value is 49.7Q, according to the formula:

[0083] Calculated:

[0084]

[0085] Therefore, the calculated temperature collected by the internal temperature sensor and the power monitored by the power monitor do not meet the above formulas, and the central control management module determines that the battery temperature and power consumption are abnormal, and sends the measurement data of the internal temperature sensor to the battery temperature control. The mod...

Abstract

The invention discloses an electric vehicle battery power and temperature intelligent management system and method. The system includes a battery temperature acquisition module, a battery temperature control module, a battery power monitoring module, a central control management module, an alarm module and a system display module; The battery temperature acquisition module, the battery power monitoring module, the battery temperature control module and the alarm module are electrically connected with the central control management module, and the system display module is respectively electrically connected with the battery temperature acquisition module, the battery temperature control module and the alarm module. The module collects the temperature of the battery, uses the battery power monitoring module to monitor the power of the battery, sends the temperature collected by the battery temperature acquisition module and the power monitored by the battery power monitoring module to the central control management module; uses the central control management module to accept the battery The temperature collected by the temperature acquisition module and the power data monitored by the battery power monitoring module are analyzed to determine the state of the battery.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an intelligent management system and method for battery power and temperature of an electric vehicle. Background technique [0002] Electric vehicle refers to a vehicle that is powered by on-board power supply and driven by a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is not yet mature. [0003] Among all environmental factors, temperature has the greatest impact on the charge-discharge performance of the battery. The electrochemical reaction at the electrode / electrolyte interface is related to the ambient temperature, and the electrode / electrolyte interface is regarded as the heart of the battery. [0004] If the temperature drops, so does the reaction rate of the electrodes, and assuming the battery voltage remains c...
