Description
technical field [0001] Embodiments of the present invention relate to the technical field of power supplies, and in particular, to a temperature compensation circuit and a charger for charging an energy storage module. Background technique [0002] As the power source of various electrical equipment, rechargeable batteries have the advantages of economy, environmental protection, sufficient power, suitable for high power and long-term use, and have been widely used, such as smart phones, tablet computers, notebook computers, smart wearable devices, electric cars, electric vehicles, etc. [0003] There are many types of existing chargers, but the charging performance is poor. Generally, a fixed voltage charging method is used to charge the rechargeable battery. However, due to the great influence of the ambient temperature on the charging process of the rechargeable battery and the capacity of the rechargeable battery, the rechargeable battery may be insufficiently charged i...
