Problems solved by technology

[0004] 1. The structure of the whole battery is complex and disorderly, and it is difficult to realize modular standardized production
[0005] 2. The connection reliability of the battery module is difficult to predict, the assembly and maintenance of the whole battery is not easy, and the maintenance cost is high
[0006] 3. Manufacturing and assembly are bulky and have different shapes, so it is difficult to realize automatic production and the production cost is high
[0007] 4. Since the entire battery pack protection plate is wrapped in plastic or inside an iron box, the heat generated during charging and discharging cannot quickly dissipate heat to the outside world, causing thermal runaway of the battery pack, causing explosions, burning and other safety hazards. To this end we propose a split lithium battery

Abstract

The invention discloses a split type lithium battery, which comprises a P1, the P1 is a battery voltage detection port and a power supply input port of a circuit chip, the P1 is electrically connected with a main control chip and a battery through a plurality of battery equalization circuits, and the battery equalization circuits comprise a first battery equalization circuit, a second battery equalization circuit, a third battery equalization circuit and a fourth battery equalization circuit; and the process time for a single lithium battery connected in series to have a safety problem is longer, the time for releasing energy outwards is longer, the energy is smaller, the evacuation time is longer and safer, and users can be served more environmentally, economically and quickly by replacing the single lithium battery or returning the single lithium battery to a factory for maintenance. Standardized modularization and automatic production are achieved bymaking monomers and assembling individual finished lithium batteries, the power lithium battery modularization module is convenient to maintain, and a dual replacement maintenance mode is achieved.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a split lithium battery. Background technique [0002] Under the pressure of energy crisis and environmental pollution, safety, environmental protection, and energy saving have become the themes of today's development. New energy lithium batteries are highly valued and vigorously promoted by the transportation and energy departments due to their advantages of small size, energy saving, environmental protection, and non-pollution. support. [0003] However, the existing block lithium battery technology also has disadvantages: [0004] 1. The structure of the whole battery is complex and disorderly, and it is difficult to realize modular standardized production. [0005] 2. The connection reliability of the battery module is difficult to predict, the assembly and maintenance of the whole battery is not easy, and the maintenance cost is high. [0006] 3. The volume ...
