Embodiment 1

[0013] Example 1, such as figure 1 with figure 2 As shown, an automatic heating system for a lithium-ion power battery for an electric vehicle includes a battery pack module, a charger, a PTC module, a BMS module, and a fan module. The battery pack module includes a battery pack composed of several batteries in series, a temperature sensor, two relays for controlling the opening and closing of the charging circuit, and a battery pack placement device. The battery pack is composed of 104 battery modules in series. The PTC module includes a thermistor and a PTC relay for controlling the thermistor to be powered on. The BMS module also includes a power supply circuit, a temperature detection circuit, an MCU and a relay control circuit. The fan module includes a fan and a fan relay for controlling the fan to be powered on. The charger and the battery pack in the battery pack module are connected through two relay controls; the charger is connected to the power circuit in the B...

Abstract

The invention discloses an automatic heating system of a lithium-ion power battery for an electric vehicle, comprising a battery pack module, a charger, a PTC module, a BMS (battery management system) module and a fan module, wherein the charger is connected with the battery pack module; the BMS module is respectively connected with the charger, the battery pack module, the PTC module and the fan module; the battery pack module is internally provided with a temperature sensor; and a temperature detection circuit in the BMS module is connected with the temperature sensor in the battery pack module. The system is used for solving the problems that the temperature is not regulated and controlled automatically, the even heating for the whole battery is difficult to realize and the use is fussy when an existing heating system heats a lithium-ion power battery.

Description

technical field [0001] The invention relates to the technical field of heating lithium-ion power batteries, in particular to an automatic heating system for charging lithium-ion power batteries of an electric vehicle at a low temperature. Suitable for vehicle lithium ion power battery heating. Background technique [0002] Energy issues are an important factor restricting the development of a country's industry, especially heavy industry. Petroleum, as the power source of traditional automobiles, is not only expensive due to the dwindling reserves, but also the exhaust gas produced by its combustion has caused environmental pollution and increased greenhouse gas emissions. Therefore, hybrid electric vehicles and pure electric vehicles, which use electric energy as part or all of the power source, emerge at the historic moment, and gradually move towards the mainstream automobile market. [0003] At present, the batteries of electric vehicles are mostly lithium-ion power ba...
