The invention provides a heat dissipation resistor, a battery voltage balancing device, a battery pack and a vehicle, the heat dissipation resistor comprises a resistor body and an insulation heat dissipation layer, and the insulation heat dissipation layer comprises insulation heat dissipation fins; the insulating heat dissipation layer covers the surface of the resistor body, and the insulating heat dissipation layer is in contact with the surface of the resistor body. According to the heat dissipation resistor, heat dissipation is carried out through the insulating heat dissipation fins in the insulating heat dissipation layer covering the surface of the resistor body, heat energy of the resistor body can be rapidly guided to the insulating heat dissipation fins and dissipated into air, rapid cooling of the resistor body is achieved, the situation that battery voltage balance is suspended due to the fact that the temperature of the resistor is too high is avoided, and the service life of the resistor is prolonged. The balancing efficiency is improved, the balancing time is shortened, the waiting time of the user is shortened, and the car use experience and satisfaction of the user are improved.

    本发明提供一种散热电阻、电池电压均衡装置、电池包及车辆,所述散热电阻包括电阻本体和绝缘散热层,所述绝缘散热层包括绝缘散热片;所述绝缘散热层覆盖于所述电阻本体的表面,并且所述绝缘散热层与所述电阻本体的表面接触。本发明的散热电阻通过覆盖于电阻本体的表面的绝缘散热层中的绝缘散热片进行散热,能够将电阻本体的热能快速地引导至绝缘散热片并散发进空气中,实现了对电阻本体快速降温,避免了由于电阻温度过高触发电池电压均衡暂停,提高了均衡效率,减少了均衡时间,减少了用户需要等待的时间,提高了用户的用车体验感和满意度。
