examples

The traditional vehicle-mounted battery is greatly influenced in a low-temperature environment, although the battery heats up after the motor runs, the battery can still be in a low-temperature state when the battery is just started or charged, and normal starting or charging is influenced;

further, the first temperature switch 33 comprises a first contact and a second contact, the first contact of the first temperature switch 33 is connected with the battery heating assembly 36, and the second contact is connected with the motor 34;

further, the motor 34 is connected with a second temperature switch 35, and the other connection end of the second temperature switch 35 is connected with the battery heating assembly 36;

specifically, the charging temperature control module 20 includes a charging plug sensing assembly 39, a low-temperature start-stop battery 32, a first temperature switch 33, a third temperature switch 38, a battery heating assembly 36 and a battery main body 37;

further, a charging plug sensing assembly 39 is connected with the third temperature switch 38;

further, the third temperature switch 38 includes a third contact and a fourth contact, the third contact of the third temperature switch 38 is connected to the low-temperature start-stop battery 32, and the fourth contact is connected to the battery main body 37;

specifically, the low-temperature start-stop battery 32 is connected with a first temperature switch 33;

specifically, the first temperature switch 33, the second temperature switch 35, and the third temperature switch 38 are respectively mounted on the surface of the battery main body 37.

Specifically, the battery heating assembly 36 is provided on the battery main body 37.

Specifically, the circuit jump temperature range of the first temperature switch 33, the second temperature switch 35 and the third temperature switch 38 is-2 ℃ to 2 ℃.

Further, the circuit jump temperature limit points of the first temperature switch 33, the second temperature switch 35, and the third temperature switch 38 are 0 ℃.

In the above scheme, when starting, if the low-temperature start is performed below 0 ℃, the low-temperature start-stop battery 32 is started first, at this time, the first temperature switch 33 switches on the battery heating assembly 36 to heat the battery main body 37, and the second temperature switch 35 is in an open-circuit state and is not supplied for the motor 34 to operate;

During charging, when the temperature is lower than zero, when a charging plug is inserted into the automobile, the charging plug sensing assembly 39 generates a corresponding signal to induce the third temperature switch 38 to start the low-temperature start-stop battery 32, and at the moment, the first temperature switch 33 is switched on to switch on the battery heating assembly 36 to heat the battery main body 37;

when the temperature of the battery body 37 rises above zero, the third temperature switch 38 connects the external power source 40 and the battery body 37 to charge the battery, thereby effectively ensuring that the battery is above zero during charging.

The low-temperature start-stop battery 32 is a super capacitor, a lithium ion capacitor, or a general high-power battery, i.e., the electrolyte is in a low-temperature state and can operate at a temperature above-40 ℃.

It should be noted that, the above-mentioned all uses zero as a temperature boundary for regulation, and in practical application, the above-mentioned all can be adjusted appropriately according to different situations, that is, can be a regulation boundary point within a certain range above or below zero.
