Embodiment Construction

[0022] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Vehicle Example:

[0024] In order to achieve the purpose of timely and automatic heating of the power battery, this embodiment proposes a vehicle, including a power battery, a battery heating system, a battery management system, a vehicle controller and a DC / DC module, such as figure 1 As shown, the DC / DC module supplies power and connects to the battery management system and the vehicle controller respectively. The battery management system controls and connects to the battery heating system. The battery management system collects and connects to the power battery. , when the vehicle is stopped and powered off, the timer starts timing and wakes up the DC / DC module every time T. After the DC / DC module is started, it supplies power to the battery management system. The battery management system detects the temperature of the power bat...

Abstract

The invention relates to a vehicle, and a heating control method of a power battery thereof, and belongs to the technical field of electric vehicles. The vehicle comprises a power battery, a battery heating system, a battery management system and a DC / DC module, the DC / DC module is in power supply connection with the battery management system, the battery management system controls and is connected with the battery heating system, the battery management system is connected with the power battery in an acquisition manner, and a timed awakening unit is arranged on the DC / DC module. When the vehicle stops and is powered off, the DC / DC module is awakened and started at regular time by the timed awakening unit to supply power to the battery management system, the battery management system detects the temperature of the power battery, and when it is detected that the temperature of the power battery is lower than a preset temperature lower limit value, the battery heating system is controlled to heat the power battery until the temperature of the power battery reaches a preset temperature upper limit value, so the link that a driver makes an appointment in advance is omitted, the vehiclecan achieve automatic heating control over the power battery according to the timing awakening unit when the air temperature is low or suddenly reduced in winter, and the service life of the power battery can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a heating control method for a vehicle and a power battery thereof. Background technique [0002] In recent years, the new energy industry has developed rapidly. With the development of new energy vehicles, at low temperature in winter, the battery temperature is low when driving in the morning or after the vehicle is parked for a long time, and the charging and discharging power of the battery is limited at low temperature, resulting in low vehicle power economy With the development of new energy vehicles, this problem limits the large-scale promotion of vehicles in the north. [0003] In view of the above problems, there are mainly two solutions in the prior art: one is to use a composite power supply, which combines the low-temperature high-power discharge performance of the supercapacitor with the energy storage function of the energy-type battery. Capa...
