Problems solved by technology

At a traction power of eg 60KW, a loss of 5% results in a power loss of 3KW
In addition, for example, in summer or in tropical regions where the outdoor temperature can reach 40°C and higher, the permissible temperature range will be exceeded, so that the service life of the battery cells will not reach, for example, ten years without cooling

Embodiment Construction

[0034] figure 1 A schematic perspective view of an accumulator 10 according to an embodiment of the invention is shown.

[0035] The battery 10 includes one battery cell or a plurality of battery cells 100 1 、100 2 、100 3 、100 4 , such as two, three, four or more battery cells. The battery 10 can include a battery case and a battery cell 100 1 、100 2 、100 3 、100 4 It may be disposed within an interior cavity of a battery housing (not shown). A large number of battery cell 100 1 、100 2 、100 3 、100 4 It can be arranged in one battery cell or in a large number of battery cells. Battery single cell, a large number of batteries 100 1 、100 2 、100 3 、100 4 , battery cells or a large number of battery cells can be arranged in one battery module or in a large number of battery modules. The accumulator 10 can thus be constructed in a modular manner. The battery 10 can be arranged in a battery system.

Abstract

The invention relates to a battery (10, 20), which includes many battery cells (1001-1004) for storing electric energy and many sensors (3201-3204) for detecting the temperature measurement values of the battery cells (1001-1004). Each of the battery cells (1001-1004) is provided with one of the sensors (3201-3204), and includes another one sensor (420) for detecting the temperature measurement value of the battery (10, 20) and also includes a monitoring device (510). The monitoring device is connected to the sensors (3201-3204) and the sensor (420), and is used for processing the temperature measurement values of the sensors (3201-3204) and the temperature measurement value of the sensor (420), so the monitoring device (510) performs redundant monitoring of the battery cells (1001-1004). The invention also relates to a battery system, and a transport tool and method.

Description

technical field [0001] The invention relates to a battery, a method for monitoring a battery, and a battery system with a battery. The invention also relates to a vehicle, in particular a motor vehicle, such as an electric or hybrid vehicle with a battery or a battery system. Background technique [0002] It is foreseeable that, whether in fixed applications such as wind power generation equipment or in mobile applications such as electric vehicles (electric vehicles, EV) or hybrid electric vehicles (hybrid electric vehicles, HEV), as rechargeable The application of new accumulators such as lithium-ion batteries or nickel-metal hydride batteries is increasing. [0003] Battery systems must meet very high requirements with regard to available energy storage (energy content), charging / discharging efficiency, reliability, service life and undesired loss of capacity through frequent partial discharges (memory effect). [0004] The battery system includes a large number of batt...
