BATTERY PACK AND VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240042897 titled 'BATTERY PACK AND VEHICLE
Simplified Explanation
The abstract of the patent application describes a battery pack with a housing and a battery, where a heat-exchanger-flow-channel is provided to regulate the temperature of the battery. The heat-exchanger-flow-channel includes an inlet, an outlet, and at least one flow section connecting them. The inlet and outlet are located higher than the flow section. The flow section is connected to the inlet through a feeding chamber, and the cross-sectional area of the feeding chamber is defined as "a" while the cross-sectional area of the inlet is defined as "b". Similarly, the flow section is connected to the outlet through a discharging chamber, and the cross-sectional area of the discharging chamber is defined as "c" while the cross-sectional area of the outlet is defined as "d". The relationships between these areas are defined as 0.5a≤b≤1.2a and 0.5c≤d≤1.2c.
- The battery pack includes a heat-exchanger-flow-channel to regulate the temperature of the battery.
- The heat-exchanger-flow-channel consists of an inlet, an outlet, and at least one flow section.
- The inlet and outlet are positioned higher than the flow section.
- The flow section is connected to the inlet through a feeding chamber.
- The cross-sectional area of the feeding chamber (a) is related to the cross-sectional area of the inlet (b) by the condition 0.5a≤b≤1.2a.
- The flow section is connected to the outlet through a discharging chamber.
- The cross-sectional area of the discharging chamber (c) is related to the cross-sectional area of the outlet (d) by the condition 0.5c≤d≤1.2c.
Potential applications of this technology:
- Electric vehicles: The battery pack with a regulated temperature can be used in electric vehicles to enhance battery performance and lifespan.
- Portable electronics: Battery packs in smartphones, laptops, and other portable devices can benefit from temperature regulation to improve battery efficiency and safety.
- Renewable energy storage: Battery packs used for storing energy from renewable sources can be optimized with temperature control for better energy management.
Problems solved by this technology:
- Battery overheating: The heat-exchanger-flow-channel helps prevent battery overheating, which can lead to reduced performance, safety hazards, and shorter lifespan.
- Inefficient battery operation: By regulating the temperature, the battery pack ensures optimal operating conditions, improving energy efficiency and overall performance.
- Battery degradation: Temperature control helps mitigate the degradation of battery materials, extending the lifespan of the battery pack.
Benefits of this technology:
- Enhanced battery performance: The regulated temperature prevents performance degradation and allows the battery to deliver consistent power output.
- Improved safety: By preventing overheating, the risk of thermal runaway and potential battery failures is reduced.
- Extended battery lifespan: Temperature control helps minimize the degradation of battery materials, leading to a longer lifespan and reduced replacement costs.
