Example Embodiment

[0044] The embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary, and is not intended to limit the scope of the present invention and its application.

[0045] Refer to Figure 1 to Figure 8 In one embodiment, a battery system includes a plurality of power supply loops arranged in parallel, each power supply loop has a number of battery packs connected in series, and each power supply loop is set to be able to use electricity under the control of a control unit The equipment supplies power or cuts off the power supply to the electrical equipment.

[0046] The use of multiple power supply loop architectures can improve the reliability and safety of the battery system. When a power supply loop fails, the power supply loop can be cut off, and other power supply loops can continue to maintain normal operation. Each power supply loop can be equipped with multiple battery packs, which can not only...

Abstract

The invention discloses a battery system. The battery system comprises multiple power supply loops which are arranged in parallel, each power supply loop is provided with multiple battery packs which are connected in series, and each power supply loop is set to be capable of supplying power or cutting off power supply to electric equipment under the control of a control unit. The invention further provides an electric automobile with the battery system, especially, a power lithium battery system or other rechargeable secondary battery systems. The battery system can also be applied to various energy storage systems. By means of the battery system and the electric automobile with the same, the problems of the battery system in the aspects such as reliability, safety, cooling and heating properties and battery protection are effectively solved.

Description

technical field [0001] The invention relates to a battery system, an electric vehicle with the battery system and an energy storage system. Background technique [0002] Existing power lithium battery systems, energy storage systems, etc. are all single power supply circuit architectures, such as figure 1 As shown, it consists of a single independent battery pack. Its disadvantage is that the combustion of a certain battery will trigger the combustion of adjacent batteries, and a chain reaction will eventually cause the entire battery pack to burn. The combustion of a large number of batteries will become uncontrollable, resulting in extreme Great harm. Therefore, when a battery is overcharged or overdischarged, and the ambient temperature is lower or higher than the operating temperature range, the entire power supply circuit must be disconnected to avoid accidents. This protection reduces the efficiency of the battery system and also reduces mileage of the vehicle. Sing...
