Abstract

The embodiment of the invention discloses a power battery charging and heating system, control method, power battery pack and vehicle. The power battery charging and heating system includes a battery, an anode and cathode of which are connected to two power supply buses, respectively. One power supply bus is provided with a first relay. A first charging interface is connected to a first connection point and a second connection point through two first charging wires and two power supply buses. The first relay is located between the battery and the first connection point. One first charging wire is provided with a second relay. A heater is connected between the two first charging wires or between two power supply buses. A connection wire of the heater and the first charging wires or power supply buses is provided with a heating relay. A detection unit is used for detecting the temperature of the battery. A control unit is connected to the relays and used for opening and closing each relay. According to the embodiment, the power battery can be preheated, and charging performance of the power battery is improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a power battery charging and heating system and control method, a power battery pack and a vehicle. Background technique [0002] Automobiles are an important means of transportation in modern society, providing people with convenient and comfortable travel services. However, traditional fuel vehicles will produce a large amount of harmful exhaust gas during use and increase the dependence on non-renewable petroleum resources. In recent years, with the continuous strengthening of people's awareness of environmental protection and energy saving, electric vehicles have developed rapidly as an important way to solve problems such as environmental pollution and resource shortage. [0003] The power battery is the power source of electric vehicles. According to the characteristics of the power battery, the charging of the power battery needs to be carried out in ...
