A battery-protecting apparatus is electrically connected to a secondary battery, a generator and a load unit of a vehicle. The generator provides electricity to the battery via the battery-protecting apparatus. The battery provides electricity to the load unit via the battery-protecting apparatus. The battery-protecting apparatus includes a detection unit, a switch, a processor, a controlling unit, a discharging loop, a wireless communication unit and a security loop.

A system for determining an operating mode of a battery includes a voltage sensor configured to detect a present voltage across terminals of the battery. The system further includes a non-transitory memory configured to store previously detected voltages across the terminals of the battery, and a previous operating mode of the battery. The system further includes a processor coupled to the voltage sensor and the non-transitory memory and configured to determine the operating mode of the battery by comparing the present voltage across the terminals of the battery to the previously detected voltages of the battery and based on the previous operating mode of the battery.

A power supply system having a wireless security module for vehicles is provided. The power supply system comprises a battery module, a power management module, an energy management module and the wireless security module. The battery module powers a starting motor of a vehicle. The power management module is used to receive a power from a power generating device. The power management module transmits the power of the power generating device into the battery module. The power management module comprises a monitoring unit and a controlling unit. The monitoring unit is used to monitor a voltage value of the battery module. When the voltage value monitored is equal to a minimum setting, the power management module is used to prevent the battery module from powering the starting motor. When the voltage value monitored is equal to a maximum setting, the power management module stops powering the battery module. The controlling unit is used to control a current value outputted from the battery module. Furthermore, when the voltage value of the battery module is equal to the maximum setting, the energy management module is used to receive a power from the power generating device. The power is transmitted into the vehicle by the energy management module.

A portable power source for power tools. The portable power source includes a housing defining a battery support and an power outlet, a circuit supported by the housing and including an input terminal on the battery support, an output terminal on the power outlet, and an inverter electrically connected between the input terminal and the output terminal, a battery power source including a battery housing supported on the battery support, at least one battery cell, and a battery terminal connected to the battery cell and electrically connectable to the input terminal, power being transferrable from the battery cell to the circuit to be output through the power outlet, and a frame connected to the housing and extending beyond a periphery of the housing and of the supported battery power source, the frame inhibiting contact with the housing and the battery power source.

This disclosure relates to a motor vehicle including remote terminals connected to battery so as to prevent electronic tampering, and a corresponding method. An example vehicle includes a battery with battery terminals. The vehicle further includes remote terminals electronically connected to the battery terminals so as to prevent electronic tampering with the battery via the remote terminals.

A battery installation method in a shelter or cabinet includes placing one or more batteries in the shelter or cabinet; connecting terminals on each of the one or more batteries to associated terminal plates with associated security screws; and connecting a bracket to a housing in the shelter or cabinet with associated security screws, wherein the bracket spans across the one or more batteries.
