Embodiment

[0028] A battery heating component such as Figure 1 to Figure 4 As shown, it includes a bottom bracket 1 as a base, a bushing assembly, a metal core 3 for heat transfer and an electromagnetic heating coil 4 for heating the metal core are arranged in the bottom bracket 1, and the bottom of the metal core 3 is set on the On the bottom support 1, the electromagnetic heating ring can be sleeved on the outside of the metal core or through the bushing assembly to achieve stable assembly. After the electromagnetic heating ring is energized, the metal core is heated, and the heat of the metal core is transferred out for heating. The bottom support Made of thermally conductive metal material to facilitate heat transfer.

[0029] In this embodiment, the metal core can be heated by the electromagnetic heating ring, and the metal core also has the function of heat transfer. During the heat transfer process, the battery in the battery compartment of the new energy vehicle can be heated. I...

Embodiment 2

[0044] A manufacturing process of a battery heating component, comprising the following steps:

[0045] Place the one-piece heat-transmitting metal bottom support on the bottom, use the bottom support as the base, and then place the metal core in the cavity of the bottom support, then put the first bushing on the metal core, and place the first bushing on the metal core. Put it on and then assemble the second bush made of non-metallic material. The second bush realizes the assembly position relationship of the metal core, the first bush and the bottom bracket through the positioning part, the positioning groove and the assembly opening, and assembles the second bush Finally, assemble the electromagnetic heating coil with binding posts, assemble the binding posts connected by the two ends of the electromagnetic heating coil in the insertion groove, and then assemble the lead terminals.

[0046] As a more specific design, the width of the lead terminal matches the width of the i...

Abstract

The invention discloses a battery heating assembly and a manufacturing process thereof, and belongs to the technical field of new energy automobile battery devices. The assembly comprises a bottom support serving as a base, a lining assembly, a metal core used for heat transfer and an electromagnetic heating ring used for heating the metal core are arranged in the bottom support, the bottom of the metal core is arranged on the bottom support, and the electromagnetic heating ring can be arranged on the outer side of the metal core in a sleeving mode or stably assembled through the lining assembly. The electromagnetic heating ring is electrified to heat the metal core, and heat of the metal core is transferred out for heating; and the problems that the cruising ability of a new energy vehicle adopting electricity as energy is greatly reduced under the condition that the environment temperature is too low or low in winter, and the loss of a battery is large in the using process are solved, the heating efficiency can be effectively improved in an electromagnetic induction heating mode, the activity of the battery is effectively improved, the cruising ability of the new energy vehicle is prolonged, and the service life of the battery is effectively prolonged.

Description

technical field [0001] The invention relates to a battery heating assembly, which belongs to the technical field of new energy vehicle battery devices. Background technique [0002] The principle of electromagnetic induction heating is that the alternating current generated by the induction heating power supply generates an alternating magnetic field through an inductor (that is, a coil), and a magnetically permeable object is placed in it to cut the alternating magnetic force line, thereby generating an alternating current (that is, an eddy current) inside the object. , The eddy current makes the atoms inside the object move at high speed and irregularly, and the atoms collide and rub against each other to generate heat energy, thus heating the object. It is a heating method that converts electrical energy into magnetic energy, so that the heated steel body induces magnetic energy and generates heat. In this way, it fundamentally solves the problem of low efficiency of ele...
