Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0037] An embodiment of the present disclosure provides a power battery system. The power battery system mainly includes a battery pack, a battery control unit, and some sensors, for example, a temperature sensor. When the battery control unit detects that the temperature of the battery pack is higher than a preset threshold through the temperature sensor, the battery control unit will control the battery pack to stop supplying external power, thereby protecting the battery pack. However, there are at least the following problems in the power battery system in the related art:

[0038] First, when the temperature in the power battery system is too high, the battery control unit controls the battery pack to stop supplying power to t...

Abstract

The invention provides a power battery system and an electric automobile and belongs to the technical field of new-energy automobiles. The power battery system comprises a temperature sensor, a temperature comparator and an alarm, wherein the temperature sensor is electrically connected with the temperature comparator and the alarm separately; the temperature comparator is used for sending warningsignals to the alarm when a current temperature received from the temperature sensor is higher than a preset temperature threshold, so as to enable the alarm to alarm. By adopting the power battery system and the electric automobile, users can understand faults of the power battery system in advance and make corresponding processing in time, and then, the electric automobile can be prevented fromstopping work under the condition of no symptom, so that the safe driving of a driver is facilitated.

Description

technical field [0001] The present disclosure relates to the technical field of new energy vehicles, in particular to a power battery system and an electric vehicle. Background technique [0002] Under the circumstances of energy crisis and environmental pollution becoming more and more serious, electric vehicles have developed rapidly due to their advantages of energy saving, low noise and zero emission. [0003] The power source of electric vehicles is the power battery system, which mainly includes battery packs, battery control units, and some sensors, such as temperature sensors. When the battery control unit detects that the temperature of the battery pack is higher than a preset threshold through the temperature sensor, the battery control unit will control the battery pack to stop supplying external power, thereby protecting the battery pack. [0004] In the process of realizing the present disclosure, the inventors found at least the following problems: [0005] W...
