Abstract: Disclosed are a battery, a battery module, a battery pack, and an electric vehicle. The battery includes a housing and at least two electrode core sets connected in series with each other and each including at least one electrode core (4). The electrode core (4) includes a positive plate, a negative plate, and an electrolyte located between the positive plate and the negative plate. The electrolyte is a solid electrolyte or a polymer electrolyte. Isolation layers (43) are arranged between opposite surfaces of two adjacent electrode core sets. Each isolation layer (43) is formed by curing an insulation adhesive coated on at least one of the opposite surfaces of the two adjacent electrode core sets.

Abstract: A battery (100) and a battery pack having the same, and an electric vehicle are disclosed. The battery (100) includes: a housing; a cover plate (30) located at an end of the housing; a terminal (40) disposed on the cover plate (30); a pole core (10) located inside the housing and having a tab (20), at least one part of the tab (20) being connected to the terminal (40); and an insulating spacer (50) covering one side that is of the at least one part of the tab (20) and that faces away from the terminal (40).

Abstract: A battery cover plate assembly, a cell, a battery module, a power battery and an electric vehicle are provided. The battery cover plate assembly includes a cover plate, a first pole, a second pole, a flipping member, a scored member, a first conductive member and a telescopic assembly. The second pole includes an upper pole and a lower pole spaced apart from each other. The flipping member is configured to turn over under the action of gas pressure inside the battery and push, by means of the telescopic assembly, the first conductive member to move to break a score, so as to electrically disconnect the upper pole from the lower pole.

Abstract: The present invention provides a start control system of a vehicle, including: an electronic control unit (ECU), a starter, an air conditioner, and a starting power supply. The starting power supply includes a starting battery and a battery management system (BMS). At a low-temperature environment, when receiving an ignition request signal sent by the ECU, the BMS detects the temperature of the starting battery. When the temperature is less than a preset threshold, the starting battery is connected to the air conditioner for a preset time, so that the starting battery effectively raises the temperature of the starting battery by means of discharging at a high current temporarily. The start control system of a vehicle improves an ignition capability of a vehicle in a low-temperature environment, extends a temperature range and an area of using the vehicle, and improves competitiveness of the vehicle. The present invention further provides a vehicle having the start control system of a vehicle.
