▎ 摘　　要

NOVELTY - The system has a flexible battery including a sensor. A charge control circuit is provided with a function of starting charging or stopping charging on the flexible battery of a signal from the sensor. The charge control circuit is configured for starting the charging of the flexible battery when the sensor detects that the flexible battery is in unfolded first form and the flexible battery is a curved second form. The charge control circuit is provided with a voltage measurement circuit and a current measurement circuit and a temperature sensor. A cover portion (120) is located outside the housing, and is provided with a function to slide against the housing. The space is provided inside the housing, and the sensor is installed in the spaced. USE - Flexible battery management system for use in electronic equipment such as wearable device e.g. smart watch or head mounted display and mobile device such as smartphone or tablet, spectacle type device, eyeglass type device. Uses include but are not limited to e.g. TV device, computer monitor, digital camera, digital video camera, digital photoframes, mobile phone, sound reproducing device and large-sized game machine such as Pachinko game machine and portable information terminal such as notebook-sized personal computer, tablet-type terminal, electronic book terminal and portable telephone set. ADVANTAGE - Since the visual field of the user is shielded from external light, the sense of presence and the feeling of immersion is enhanced. The weight of the casing on the front head side and the weight of the flexible battery on the rear head side are balanced by adjusting the center of gravity of the head mounting type device the wearing feeling is improved. The electric conductivity of the granular active material and the graphene or the graphene compound in a smaller amount than that of the ordinary conductive material is improved. Thus, the ratio of the active material in the active material layer is increased, and the discharge capacity of the battery is increased. Since the oxidation resistance is improved when the ceramic-based material is coated, the deterioration of the separator in the case of high voltage charging/discharging is prevented, and the reliability of the battery is improved. The separator and the electrode are provided into close contact with each other, and the output characteristics are improved. The safety of usage of battery is improved. The wearing feeling of user is enhanced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electronic equipment. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a configuration of an electronic equipment. 100Electronic equipment 101Casing 102Display unit 119Hinge portion 120Cover portion
