In a battery module of the invention, a first battery row and a second battery row have the same number of cylindrical batteries (2) arranged side by side, and both ends in the battery axis direction of each of the battery rows are held by holding frames (3). Each holding frame (3) is formed in a rectangular solid where an inner frame (4) and two outer frames (7, 8) are separably connected to each other. In each holding frame (3), semicircular arc-shaped cutout-like holding receiving sections (4a, 7b, 8b) of the same number as the number of the batteries in the battery rows are formed in bothsides of the inner frame (4) and in those sides of the two outer frames (7, 8) which face the inner frame (4), and half sections of the cylindrical batteries (2) are fitted in the holding receiving sections (4a, 7b, 8b). Two adjacent cylindrical batteries (2) are electrically connected via an inter-battery connection plate (9).

The invention relates to a sectional multi-order compensation high-precision voltage and current reference circuit which is used for generating stable reference voltage and current to provide voltage and current bias for other modules inside. The reference circuit is an on-chip circuit and comprises a basic band gap circuit, a low-temperature first-order negative temperature coefficient compensation circuit, a high-temperature high-order positive temperature coefficient compensation circuit, a voltage stabilization trimming circuit and a trimming logic circuit. Through sectional multi-order compensation of basic band gap voltage, the reference circuit has high temperature stability and is small in output deviation in a wide temperature range. By designing the trimming circuit, output bias caused by process deviation can be adjusted, so that precision of output voltage is further guaranteed. The reference circuit is simple in structure, high in precision and suitable for various analog integrated circuits.
